Purpose: To assess the MR arthrographic findings of bicipital tenosynovitis in correlation with arthroscopy.Design and Patients: The shoulder MR arthrographies of 500 consecutive patients were retrospectively analyzed for signs of bicipital tenosynovitis and associated pathologies. Forty patients (8%) had MR evidence of bicipital tenosynovitis, but only 17 (3%) with arthroscopic confirmation were included in the study. The MR findings in these patients were compared with those of 10 patients with rotator cuff lesions but arthroscopically normal long biceps tendons. MR arthrography was performed with 10-15 ml of a 250 mmol/l gadoterate meglumine (Gd-DOTA) solution injected under fluoroscopic guidance, and transaxial, oblique coronal and sagittal MR sequences were obtained.Results: All 17 patients showed one or more abnormal findings: signal increase in the tendon with or without fusiform distension was seen in 12, surface irregularities in six, adhesions in 11 and noncommunicating effusions of the tendon sheath in six. Associated abnormalities of the rotator cuff were present in 16 while the seventeenth patient had glenohumeral synovitis without rotator cuff pathology. MR arthrograms correlated with arthroscopic findings in the joint but comparison was not possible in the intertubercular groove portion of the biceps tendon. None of the 10 patients with an arthroscopically normal biceps tendon showed any of the MR findings of bicipital tenosynovitis.Conclusion: Bicipital tenosynovitis is detectable by MR arthrography. In most cases it is an associated finding of rotator cuff abnormalities and likely to have a similar etiology. When lesions of the anterior rotator cuff are recognized, the biceps tendon should be scrutinized for inflammatory changes. [ABSTRACT FROM AUTHOR]

The chest radiographs of 23 children, aged between 4.2 to 15.4 years with serologically proven mycoplasmal pneumonia were reviewed and correlated with the findings in literature. Three different patterns of infiltration were seen in equal frequency: 1) peribronchial and perivascular interstitial infiltrates, 2) patchy consolidations and 3) homogeneous acinar consolidations like groundglass. The lower fields of the lungs were mostly affected. Pattern 1 was always observed bilaterally. Enlargement of the hilar glands was a common finding. Pleural effusion was rare. Numerous differential diagnoses, especially viral pneumonias, feature the heterogeneity of the infiltration patterns. As no pattern is pathognomonic for mycoplasmal pneumonia clinical symptoms and signs, the epidemiological situation and laboratory data may confirm the diagnosis. [ABSTRACT FROM AUTHOR]
