In a case of juvenile rheumatoid arthritis with large synovial cysts, cyst fluid aspiration was performed to relieve pain, but recurrence was prevented with salicylate therapy alone. The mechanism of formation of synovial cysts is discussed.
Rheumatoid synovial cyst of the hip joint in a 52-year-old man including iliopsoas bursal extension was demonstrated by arthrography and excision biopsy. Surgical excision of the cyst and femoral head replacement were carried out. There was no recurrence for 15 months postoperatively. The condition should be suspected in patients with degenerative changes in the hip joint and adjacent unexplained palpable mass.
Four additional cases of synovial cyst (ganglion) arising from the facet joint between L4 and L5 are reported. Only five such cases have been reported in the past. For the first time impressive and characteristic myelographic findings are described, which make a preoperative diagnosis possible in these cases.
The authors operated on a tumorlike synovial cyst of the hip, associated with an idiopathic osteonecrosis of femoral head. So far, about fifty cases have been reported in the medical litterature with various names, and association with hip joint disease. The problems of diagnosis are discussed.
A previously unreported case of a synovial cyst of a temporo-mandibular joint imitating a parotid tumour is described. A surgical approach involving a total mobilization of the facial nerve is outlined.
A new simple and safe technique for the detection of synovial cysts is described. This investigation employs combined transmission-emission scintigraphy following intra-articular injection of 169Yb-DTPA. Twenty-two joints were investigated in 18 patients. A high degree of correlation was found between clinical findings and the results of this investigation. The major advantages of this method are low local radiation to synovial linings, adequate visualisation of periarticular soft tissue, and small volumes required for intra-articular injection.
A 47-year-old paraplegic patient is described who developed a massive synovial cyst of the upper extremity. The cyst developed in combination with a tear of the rotator cuff and the long head of the biceps tendon and involved the fasica surrounding the long head of the biceps. The increased pressure in the cyst resulted in a compartment syndrome of a portion of the long head of the biceps muscle. A review of the literature revealed no similar case.
A man with gonococcal urethritis who developed septic arthritis of both knees is described. The arthritis was complicated by rupture of bilateral synovial cysts. A rise in serum gonococcal complement-fixation antibody titer was demonstrated. Complement-fixing gonococcal antibodies with a high titer were observed in this synovial fluid. The patient responded well to antibiotic treatment and there was no permanent damage to his knee joints.
Compression of the ulnar nerve within or near the canal of Guyon has been ascribed to numerous intrinsic and extrinsic factors. The anatomy of the region is discussed, and a review of the reported causes of ulnar nerve compression is presented. A case of ulnar nerve compression at the wrist secondary to a rheumatoid synovial cyst is reported. Prompt decompression resulted in clinical and electromyographic recovery of sesory and motor function.

Four cases of a ganglion of the hip joint are reported. Besides the symptomatology and the clinical findings, special attention is payed to the anatomical relationship. The weak part of the joint capsula medially to the longitudinal traction of the ligamentum iliofemorale and laterally to the ligamentum pubofemorale was found to be the source of these ganglions. The most helpful diagnostic measure is arthrography through a lateral access. Therapy consists of resection of the cystic tumor, and careful closure of the hip joint capsula will prevent recurrence.
Sixty-two patients with popliteal or calf synovial cysts defined by arthrography are presented, of whom 34 had the pseudothrombophlebitis (PTP) syndrome. While the clinical manifestations of PTP may closely mimic thrombophlebitis, including the presence of calf pain, swelling and warmth, and a positive Homans' sign, the helpful descriminating features include the presence of inflammatory joint disease (91%), concomitant pain and swelling of the knee (94%), a demonstrable knee effusion (91%) and the absence of deep venous tenderness or cord. Except for seven patients with large intact Baker's cysts, the PTP syndrome was associated with synovial cyst dissection (18 patients), rupture (5 patients), or both (4 patients). Of those with arthrographically demonstrated Baker's cysts, only 27 (44%) had a palpable mass in the popliteal fossa and another 4 (12%) a mass in the calf. Popliteal fossa pain was noted in 22 (35%). Thus, clinical features are far less sensitive than arthrography in the diagnoses of both synovial cysts and pseudothrombophlebitis. Among patients with rheumatoid arthritis there were no differences in the severity or duration of disease or the extra-articular features in patients with and without synovial custs or the PTP syndrome. The therapeutic implications of pseudothrombophlebitis are of major significance with respect to the avoidance of anti-coagulation and the prompt response to intra-articular corticosteroids. Possible mechanisms of synovial cyst formation and unusual presentations of synovial cysts are discussed, and the literature is reviewed.
In the embryo the periarticular fibroblasts were the producers of the greater part of the joint they surround in later life, as well as of the tendon sheaths and bursae. It is postulated that adult fibroblasts have retained atavistic arthrogenic properties, and may react to traumatizing, inflammatory and oncogenic stimuli by forming periarticular joint-like structures: "arthromas" such as ganglia, meniscal cysts, synovial cysts, synovial sarcoma and subcutaneous nodules. The arthroid nature of these growths manifests itself by the presence of a central cavity, which can be identified as a synovial cavity by histologic, histochemical and electron-microscopic methods. In case of affection of the joint all of these adnexa may be involved. A resemblance of these structures to embryonic joint tissues has been noted for years. The nature of the subcutaneous nodule is discussed at some length. It may contain one or more synovial clefts; synovial elements may be found in its centre by histochemistry and electron-microscopy. Recent and personal findings shed a new light on palisading cells, which may be fibroblasts, having taken up again their embryonic task as synovioblasts. From periarticular fibroblasts thus three kinds of tumors may arise; benign (ganglia, cysts, subcutaneous nodules), malignant (synovial sarcoma) and "semi-malignant" (pannus in rheumatoid arthritis).
