Prevalence and size of meniscal cysts, ganglionic cysts, synovial cysts of the popliteal space, fluid-filled bursae, and other fluid collections in asymptomatic knees on MR imaging.

OBJECTIVE: The purposes of this study were to evaluate the prevalence and determine the size of meniscal cysts, ganglionic cysts, synovial cysts of the popliteal space, fluid-filled bursae, and other fluid collections on MR images of asymptomatic knees. MATERIALS AND METHODS: MR images of 102 asymptomatic knees were evaluated with regard to the prevalence of meniscal cysts, ganglionic cysts, synovial cysts of the popliteal space, fluid-filled bursae, and other fluid collections. The MR examinations were performed in patients (mean age, 42.8 years; age range, 18-73 years) with clinically suspected meniscal lesions in the contralateral knee. The craniocaudal, anteroposterior, and mediolateral diameters of detectable abnormal fluid collections were measured. RESULTS: Medial meniscal cysts (mean size [craniocaudal x anteroposterior x mediolateral], 9 x 6 x 13 mm) were found in four asymptomatic knees. Neither lateral meniscal cysts nor ganglionic cysts of the cruciate ligaments were identified. Twenty-six synovial cysts of the popliteal space (Baker's cyst)-consisting of 11 gastrocnemius portions (mean size, 19 x 8 x 10 mm) and 15 semimembranosus portions (mean size, 20 x 7 x 9 mm)-were found in 19 knees. Twenty-four (92%) of these cysts had a maximal diameter of 30 mm or less. Fluid-filled bursae were found in 49 knees. The deep infrapatellar bursa was most commonly involved (42 knees; mean size, 6 x 3 x 5 mm). Fluid-filled anserine bursae (mean size, 27 x 12 x 10 mm) were detected in five knees. CONCLUSION: Meniscal cysts may be present in asymptomatic knees, at least on the medial side. Synovial cysts of the popliteal space can be found in approximately one fifth of asymptomatic knees. Their maximal diameter is usually smaller than 30 mm.

Nonoperative treatment of an interosseous ganglion cyst.

Ganglion cysts of the knee are being reported more frequently secondary to an increased rate of magnetic resonance imaging studies. Although knee pain is the impetus for imaging, ganglion cysts are often incidental findings. Nonoperative treatment is a successful therapeutic option. We report a patient with variable pain presentations over the course of her treatment. The pattern of complaints pointed to different primary etiologies about the knee, but all were common to an interosseous ganglion cyst. A stepwise assessment and expansion of the differential diagnosis allowed for appropriate utilization of modalities and limited morbidity with nonoperative therapy.

Fine-needle aspiration cytology of ganglion cysts.

Ganglion cyst is a relatively common lesion resulting from mucoid, cystic degeneration of soft tissues adjacent to a joint space. Aspiration of cyst contents has been increasingly advocated as a diagnostic and, in some instances, therapeutic modality. We report the fine-needle aspiration cytologic (FNAC) findings from seven cases of ganglion cyst. These include the aspiration of thick, gelatinous fluid and a smear comprised of rare histiocytes embedded in a mucoid matrix. Although these findings are nonspecific, we believe that in the appropriate clinical setting, the diagnosis of ganglion cyst can be made with confidence by FNA.

Presentation of a unique ganglionic cyst.

Ganglions, often referred to as ganglionic cysts or synovial cysts, are benign, fluid-filled, cystic swellings. Ganglions are often isolated in the wrist and hand, although they are not uncommon to the foot. Surprisingly, with a high rate of occurrence there has been little discussion in the literature. The authors briefly review ganglionic cysts and present an interesting case report of an unusually large ganglion in the foot.

Relationship between dorsal ganglion cysts of the wrist and intraosseous ganglion cysts of the carpal bones.

Soft tissue ganglion cysts are the most common benign tumours of the wrist; their pathogenesis remains controversial. We prospectively screened the radiographic appearance of the wrists of 51 patients presenting to a single surgeon with dorsal wrist ganglions during a one-year period. Postero-anterior and lateral radiographs were systematically performed looking for possible associated intraosseous ganglion cysts. There were 51 dorsal soft tissue ganglion cysts in 51 patients. We detected 29 associated intraosseous ganglia in 24 patients (47%): 16 ganglia in the lunate bone (55%), 5 in the capitate bone, 7 in the scaphoid and 1 in the trapezoid. Mean size of the intraosseous ganglia was 3 mm (range, 2 to 5 mm). This high prevalence of intraosseous ganglia in association with soft tissue ganglia has to our knowledge never been reported previously. A common aetiology for these two types of ganglion cysts may explain this high association rate.

Urografin injection demonstrated soft tissue ganglion communication with an intraosseous ganglion cyst.

Intraosseous ganglion cysts rarely occur in the hand or wrist. We present a case of a soft tissue ganglion cyst that communicated with the intraosseous ganglion of the scaphoid. Typical diagnostic studies include radiography, computed tomography, and magnetic resonance imaging. The diagnosis was made in this case by injection of Urografin into the soft tissue ganglion. The patient underwent excision of both ganglion cysts, resulting in a satisfactory outcome.

"Disc cysts" and "posterior longitudinal ligament ganglion cysts": synonymous entities? Report of three cases and literature review.

OBJECTIVE AND IMPORTANCE: Extradural cysts intimately associated with relatively normal lumbar discs have rarely been reported. Histologically nonspecific, most have been designated posterior longitudinal ligament (PLL) or annulus fibrosus (AF) "ganglion cysts." Recently, "disc cysts" have been distinguished as a separate entity, mostly on the grounds of cyst-disc communication. CLINICAL PRESENTATION: Three young male patients presented with unilateral sciatica. In all cases, magnetic resonance imaging demonstrated rounded, cystic lesions (i.e., hypointense on T1- but hyperintense on T2-weighted scans) adjacent to minimally dehydrated, nonherniated disc spaces. INTERVENTION: At surgery, each cyst was found intimately related to either the AF (Case 3) or the PLL (Cases 1 and 2) of the adjacent disc; and direct disc-space communication was evident in Case 3. After cystectomy, with or without discectomy, all patients achieved complete and long-lasting resolution of their sciatic symptoms. Histological appearances were typical of ganglion cysts in all three cases, with evidence of prior hemorrhage in Cases 1 and 3. CONCLUSION: Our results and those of others suggest that all such cysts are ganglion cysts that derive from either the AF or the PLL at the disc level. Although disc cysts might be AF ganglion cysts exhibiting disc communication, their separate distinction is probably unnecessary. Cystectomy alone affords complete symptomatic remission; discectomy is usually unnecessary. Although anticipated with ganglia in general, neither spontaneous resolution nor postoperative recurrences have been witnessed. Unlike ganglia in general or juxtafacet ganglion cysts, such cysts seem to be unusually restricted to young men.

Intraspinal extradural ganglion cyst.

Occurrence of ganglion cysts in the spine is extremely rare. Common symptoms include intermittent lumbar pain and pain at night. Neurological examination to distinguish from other etiologies of radicular pain may be difficult. The L4-L5 level is the most common sight of occurrence. Radiographically, degenerative changes, particularly spondylolisthesis, are a common finding. MRI appearance of the cysts is variable, according to the composition of the cyst. A ganglion cyst should be considered in the differential of radicular pain in the presence of degenerative changes of the lumbar spine.

[A case of lumbar ganglion cyst causing radiculopathy].

Ganglion cysts represent a rare pathology mostly encountered in the lumbar region of the spinal column. Magnetic resonance imaging revealed a ganglion cyst at the L4-5 level in a 46-year-old woman who had a complaint of long-standing pain in her right leg. The cyst was completely excised following total laminectomy at L4. After surgery, her symptoms and neurological signs completely disappeared.

Meniscal and ganglion cysts of the knee: MR evaluation.

Meniscal and ganglion cysts frequently present as palpable masses of the knee but occur at different locations than do popliteal cysts. Meniscal cysts also may be discovered incidentally on studies performed for suspected internal derangement. Sixteen cystic lesions of the knee were evaluated with MR, including 11 meniscal cysts and five ganglion cysts. Scans were performed at 1.5 T by using a transmit/receive extremity coil or a receive-only surface coil. Standard spin-echo imaging, including at least one long-TR/asymmetric-TE sequence, was performed in all cases. In six patients, gradient-echo, reduced flip-angle sequences also were done. All meniscal cysts (but none of the ganglion cysts) were associated with horizontal meniscal tears. Cysts were visualized best on the long-TR/TE images; meniscal tears were seen best on the short-TR/TE and long-TR/short-TE images. Meniscal tears and cysts were also seen well on the fast-scanning sequences. Septations were noted in four meniscal cysts and in four ganglion cysts on the long-TR/TE images. Long-TR/TE images were also useful in showing the relationship between the cyst and joint capsule in three of the ganglion cysts. MR imaging is an effective, noninvasive method for evaluating cystic lesions of the knee. Meniscal cysts are always associated with underlying horizontal meniscal tears, which can be detected with MR. Ganglion cysts are not associated with meniscal tears, but may have connections to the joint capsule, which can be detected with MR.

Intraosseous ganglion cyst of the scaphoid.

Intraosseous ganglion cysts are rare causes of hand and wrist pain. Differential diagnosis of painful cystic radiolucent carpal lesions includes osteoid osteoma and osteoblastoma. Isolated cases of ganglion cysts occurring in the lunate, scaphoid, pisiform, hamate, triquetrum, capitate, metacarpal, and phalanx have been reported. A case of intra-articular intraosseous ganglion cyst of the scaphoid is presented. A 49-year-old right-handed woman presented with a 3- to 4-month history of progressive left-wrist pain. No history of trauma was reported. Conservative treatment with anti-inflammatory medications before referral was unsuccessful. Examination revealed marked tenderness in the region of the volar scaphoid proximal pole as well as tenderness overlying the dorsal radial styloid. No palpable masses were present. Wrist motion was not limited. Grip strength was symmetric. Radiographic studies revealed a cystic lesion eroding the radial-volar surface of the scaphoid waist. Magnetic resonance imaging studies demonstrated the cystic lesion to be of the penetrating type, originating from the radiocarpal joint and eroding into the scaphoid. The patient underwent radial styloidectomy, excision of the ganglion cyst, curettage of the scaphoid lesion, and bone grafting with radial styloid bone. Intraosseous carpal ganglion cysts, although rare, present with chronic wrist pain and should be included in the differential diagnosis.

Intraspinal extradural ganglion cyst of the cervical spine.

Intraspinal ganglion cyst is an uncommon lesion, which occurs most frequently in the lower lumbar region; occurrence in the cervical region is extremely rare. We report a case of ganglion cyst in the cervical region and describe its clinical pathological and radiological findings. A 59-year-old man presented with sudden lower limbs weakness and numbness below the nipple level. Magnetic resonance imaging revealed an intraspinal extradural lobulated cystic lesion at the level of C6-7 in contact with the left facet joint and posterior erosion of the spinal process at C7. The spinal cord was severely compressed by this lesion which was hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging and short T1 inversion recovery. The cyst wall was strongly enhanced after contrast injection. Intraoperatively, the mass was found to arise from the capsule of the C6-7 facet joint. The excised cyst contained jelly-like fluid. The patient's neurologic symptoms had fully recovered 20 days after the operation. The histopathologic analysis was consistent with ganglion cyst. Ganglion cyst of the cervical region is extremely rare, but must be considered in the differential diagnosis of intraspinal extradural compressive syndromes.

Sternoclavicular joint ganglion cysts in young children.

Ganglion cysts originating from the sternoclavicular joint in children have not been previously reported. In this study, 5 children who presented with a small mass over the anterior aspect of the sternoclavicular joint were evaluated and treated. Only 1 patient was symptomatic. A ganglion cyst was suspected in each case and confirmed by magnetic resonance imaging in 3 patients and ultrasound in one patient. Excisional biopsy was performed in 3 patients and the diagnosis of a ganglion cyst confirmed histopathologically. No patient has had a recurrence. Observation of asymptomatic cystic lesions that arise in the sternoclavicular location is recommended.

Intra-articular ganglion cyst of the knee.

Ganglion cysts of the knee are extremely uncommon. They usually cause non-specific symptoms and do not produce classical signs. Advances in imaging techniques as well as widespread use of arthroscopy have made detection of these cysts easier, and most can be treated arthroscopically. Ganglion cysts arising within the infrapatellar fat pad are even more uncommon. We report a case of a young lady with a giant intra-articular ganglion within the infrapatellar fat pad that was treated by open excision.

Arthroscopic decompression of a ganglion cyst causing suprascapular nerve compression.

Ganglion cysts causing suprascapular nerve compression are an uncommon cause of suprascapular nerve compression. The advent of magnetic resonance imaging (MRI) and its application in patients with shoulder pain has improved the ability to diagnose cystic lesions causing extrinsic compression of the suprascapular nerve. Traditionally, treatment of suprascapular nerve compression by a ganglion cyst has required open cyst excision through either a deltoid and infraspinatus muscle takedown or a muscle splitting approach. We present three cases of suprascapular nerve compression by a ganglion cyst in which the cyst was decompressed arthroscopically. In each case the patient's symptoms resolved after arthroscopic cyst decompression, and a postoperative MRI does not demonstrate reaccumulation of the cyst fluid. Arthroscopic ganglion cyst decompression is a well-tolerated approach to this problem that avoids the morbidity of an open surgical procedure. The absence of recurrent cyst formation combined with resolution of the symptoms attests to the success of this method.

Ultrasound-guided aspiration of posterior cruciate ligament ganglion cysts.

Intra-articular ganglion cysts of the knee joint are rare. Percutaneous aspiration of ganglion cysts of the knee, which has both diagnostic and therapeutic value, has been described, but usually under guidance by computed tomography (CT). We describe ultrasound-guided aspiration of posterior cruciate ligament cysts in two patients.
