Computed tomography in the diagnosis of subcapsular and perirenal hematoma.

Six patients are described in whom subcapsular and perirenal hematomas were demonstrated by computed tomography. This new diagnostic tool provided a rapid noninvasive means of visualizing the hematoma, its extent, location, and relationship to renal parenchyma. Serial examinations were used to follow progress of the hematomas toward resolution. Correlation is made with conventional rediography, angiography, and gray scale ultrasound.
