RESUMO
Rapid development of low density bilateral lesions in the brain due to deep venous thrombosis in Systemic Lupus Erythematosis is described. To the best of our knowledge, this type of symmetry, distribution and appearance of brain infarcts in CT due to deep venous thrombosis has not been reported previously.

The computed tomography (CT) appearance of a large cystic caseating granuloma in the middle mediastinum is reported. CT is helpful in evaluating the extent and density of the lesion and its relationship to neighboring structures.

The authors, in a careful prospective study, report the accuracy of MRI to be comparable to that of pneumoarthrography and arthroscopy in the diagnosis of internal derangements of the knee.

Sixty-nine children younger than 13 years of age with urinary tract infection were evaluated to identify risk factors for treatable urologic problems; i.e. those requiring surgery or prolonged antibiotic prophylaxis. All children had a renal ultrasound, intravenous pyelogram and voiding cystogram performed 4 to 6 weeks after the infection. Eleven children with treatable problems were identified, 10 with vesicoureteral reflux and 1 with a ureterocele. For identification of treatable problems the predictive value of a positive test was: (1) fever, 10 of 24 (41.7%); (2) abnormal D-deaminoarginine vasopressin renal concentrating ability, 8 of 24 (33.3%); (3) serum C-reactive protein greater than or equal to 1.0, 8 of 25 (32.0%); (4) Elevated urine N-acetylglucosaminidase, 5 of 16 (31.2%); (5) erythrocyte sedimentation rate greater than or equal to 25, 6 of 21 (28.6%); and (6) age less than 5 years, 10 of 43 (23.3%). Absence of fever denotes a low risk (less than 3%) of finding a treatable problem. Afebrile girls older than 5 years of age can have radiologic evaluation deferred until infection recurs. The presence of fever indicates a high risk of treatable urologic problems (41.7%) and warrants complete radiologic evaluation with the first urinary infection.
