Submucosal hemorrhage of the renal collecting system.
Two cases of submucosal hemorrhage in the renal pelvis and ureter are presented. The roentgenographic appearance was identical to that of pyeloureteritis cystica but without evidence of urinary tract infection and, in 1 case, the submucosal impression resolved rapidly. When nodular, submucosal filling defects are demonstrated in the renal collecting system in the clinical setting of anticoagulant therapy or trauma, a diagnosis of submucosal hemorrhage should be considered.
