Spontaneous renal hemorrhage.
This report of 9 cases of spontaneous renal hemorrhage illustrates the wide variety of responsible conditions that may be found in a small series and the tendency for some of these conditions to coexist. In particular, all 3 patients with a bleeding diathesis had an associated anatomic lesion, and it was concluded that this group of patients required aggressive radiologic investigation. Three main clinical presentations were identified: sudden severe flank pain, symptomless hypertension, and a palpable mass with few or no symptoms. The radiologic signs are reviewed with emphasis on a recently described sign of streaky retroperitoneal fat. Treatment is discussed briefly.
