Between April 1982 and March 1984 7 pathologically confirmed cases of @entity7578 ( @entity7578 ) were diagnosed at our institution. Only 1 case had been seen in the preceding twenty years. Four @entity1 had @entity791 ( @entity791 ). The others had @entity1072 , @entity978 , and @entity1252 . All @entity1 presented with progressive @entity51 . In most, the initial computed tomographic (CT) scan was disproportionately less abnormal than the clinical findings. In 5 @entity1 the first CT scan revealed @entity62 which lacked mass effect and did not enhance with contrast agent. The lesions were observed to enlarge progressively on CT scans but often lagged behind the rate of clinical evolution. Although 3 @entity1 were treated with @entity2592 , none improved. @entity7578 had similar clinical, radiographic, and pathological features in the @entity791 and non-AIDs @entity1 . Of 79 @entity791 @entity1 cared for at our institution between December 1979 and December 1983, 3.8% had @entity7578 . @entity7578 should be suspected in @entity791 @entity1 in the presence of the characteristic CT features, especially when CT-clinical dissociation occurs.
