Detection of intraarticular bodies of the elbow with saline arthrosonography.

AIM: To assess whether ultrasound with intraarticular injection of saline increases the detection of intraarticular bodies of the elbow. SUBJECTS AND METHODS: Twelve patients (age range 21-42 years, mean 29 years; 8 male, 4 female) referred over a 2-year period with an equivocal history of elbow locking and plain radiographs had a joint injection of at least 12 ml of sterile saline during ultrasound examination. No patient had a joint effusion before injection. Surgical correlation was available in six patients. RESULTS: Ten patients had intraarticular bodies but these were demonstrated only after joint injection in six patients. Arthroscopy performed in six patients confirmed intraarticular bodies in five. Radiographs were falsely positive in one and falsely negative in seven patients. CONCLUSION: Joint injection improves the sonographic evaluation and conspicuity of small and radiographically occult intraarticular loose bodies in the clinically equivocal elbow. The procedure is simple, quick, well tolerated and reproducible.

Synovial desmoplastic fibroblastoma of hip joint with bone erosion.

A 78-year-old woman presented with pain at the left hip. Initial radiographs showed minimal age-related changes. Over the next 2 years she developed large erosions in the left femoral neck and proceeded to hip replacement. Histological examination showed bland spindle cells in a loose and hyalinised collagenous stroma considered to represent a desmoplastic fibroblastoma (collagenous fibroma). This is the first reported case of synovial desmoplastic fibroblastoma.

Non-communicating intramuscular ganglia.

Intramuscular ganglia are rare. Most of the previously reported cases were connected with an adjacent joint. We present the imaging findings in three patients who had intramuscular ganglia that were not connected with a joint. Magnetic resonance showed a septated, encapsulated mass that was isoor hypointense to muscle on T1-weighted and hyperintense on T2-weighted images. A post-contrast T1-weighted scan in one patient showed minimal capsular enhancement. Ultrasound performed in one case showed an encapsulated, anechoic mass.

Ultrasound in the assessment of metatarsalgia: a surgical and histological correlation.

AIMS: To assess the reliability of ultrasound in the evaluation of metatarsalgia in a typical clinical setting. METHODS AND MATERIALS: The clinical records, ultrasound findings, surgical outcome and histology of patients with metatarsalgia referred for ultrasound evaluation were reviewed. All ultrasound examinations were performed by the same operator via a plantar approach using high resolution linear array probes. RESULTS: Thirty-seven patients were examined, age range 23 to 74, mean 49.6 years; thirty-one were female. Thirty-seven intermetatarsal masses were found in 32 patients. To date 26 patients have undergone surgery and 28 lesions (26 Morton's neuromas, one angiolipoma and one angioleiomyoma) have been excised. There were no false-positive ultrasound examinations. A solitary neuroma was missed. Sensitivity was 96% and positive predictive value 100%. CONCLUSION: Ultrasound is a valuable tool in the evaluation of metatarsalgia and has high sensitivity and positive predictive value for the detection of intermetatarsal masses. It provides exact localization prior to surgical resection and detects unsuspected additional lesions.

Diffuse neurofibroma of the ankle.

PURPOSE: To correlate the imaging and histological findings in diffuse neurofibroma. PATIENTS AND METHODS: Retrospective review of clinical, imaging and histological findings in two patients with diffuse neurofibroma. RESULTS: CT demonstrates diffuse infiltration of the deep and subcutaneous fat, isodense to muscle. Magnetic resonance imaging shows extensive infiltration of the subcutaneous and deep fat that envelops tendons and vessels but does not involve bone. Superficial masses enhance homogeneously after intravenous gadolinium. The reticular nature of the deep infiltration is seen on all sequences but is most conspicuous on post-gadolinium T1-weighted images which show tumour enhancement and non-enhancing hypointense soft tissue strands. Magnetic resonance angiography and Doppler ultrasound may show enlarged vessels, high blood flow and vascular pools. CONCLUSION: Diffuse neurofibroma has a characteristic appearance on magnetic resonance that is best shown on post-gadolinium T1-weighted images.

Posterior vertebral rim fractures.

Fracture of the posterior vertebral endplate is a cause of low back pain in adolescents and young adults. Clinically it resembles an acute disc prolapse with low back pain and radiculopathy, but may present with neurogenic claudication due to spinal stenosis in older patients. The lesions may be incidental findings. Plain radiographs are diagnostic in about 40% of cases. CT shows the fracture fragment and vertebral defect in most cases but the fracture fragment may be overlooked on MRI. Accurate diagnosis is essential as the surgical technique for disc herniation is inadequate for endplate fractures. In this pictorial essay we review the imaging findings.

Primary muscle lymphoma.

Primary muscle lymphoma is rare. Less than 50 cases have been described. The clinical and radiological features of muscle lymphoma are presented in this series of six cases. Most patients present with solitary or multiple masses which may be painful. Clinical presentation varies from the indolent to the rapidly progressive. Systemic symptoms occur in a minority. In most cases, ultrasound shows an ill-defined hypoechoic mass but apparent coarsening of fibroadipose septa and swelling of muscle bundles may occur. CT shows an iso/hypo dense mass. On MR the mass appears iso/minimally hyperintense to muscle on T1W and enhances, and hyperintense on T2W, proton density and fat suppression sequences. Infiltration of the subcutaneous fat is a striking feature in a majority of cases on CT and MR. The diagnosis can be established by ultrasound guided biopsy and should be performed urgently in HIV positive patients to exclude pyomyositis.

Cervical spine surgery in patients with rheumatoid arthritis: an appraisal.

OBJECTIVES: To review the outcome of surgery undertaken to stabilise the neck in patients with rheumatoid arthritis performed over a five year period, to compare the results with those of previous reports, and to identify factors that may predict surgical outcome. METHODS: Outcome was assessed at time of discharge from hospital after surgery by review of patients' notes, and at follow up by patient interview, clinical examination, anonymous questionnaire, and cervical spine radiograph. The Ranawat classification of neurological impairment and Steinbrocker functional classification were used. RESULTS: Thirty nine patients underwent 44 procedures; 28 patients were available for review after a mean period of 29.8 months (range 12-65 months). Fourteen patients had preoperative neurological impairment and were available for follow up; 13 returned the questionnaire. Four (29%) had improved Ranawat class, nine were unchanged, and one had deteriorated. Nine (69%) reported a subjective improvement in neurological symptoms by questionnaire, even though the Ranawat class was unchanged in five. Twenty five of the patients reviewed had pain before operation; 21 returned the questionnaire. Pain relief was reported by direct questioning and questionnaire in 76% and 67% of patients, respectively. Overall, 67% felt that surgery had been successful. Surgery was more successful in producing symptomatic relief in patients with neck or radicular pain than in those with neurological deficit, but did prevent progression of neurological symptoms. CONCLUSIONS: Our results are similar to those from other centres. Overall patient satisfaction with surgery was good. Surgery was more likely to produce symptomatic relief in patients with neck or radicular pain before operation than in those with neurological deficit. The greater subjective improvement in neurological symptoms as judged by questionnaire probably reflects the relative insensitivity of the Ranawat classification in detecting change in neurological status; previous reports of poor outcome for patients with neurological symptoms who undergo surgery may in part be a reflection of the insensitivity of this method of assessment. No clear factors emerged which allowed prediction of those patients at greatest risk of operative mortality. In particular, an increased risk of neurological compromise appeared to confer no additional risk of immediate perioperative death. Our data support the suggestion that early surgery to correct symptomatic atlantoaxial subluxation may prevent progression of instability.
