title: Bilateral intrarenal hematomas from anticoagulants.
abstract: A case is reported in which anticoagulant therapy for thrombophlebitis and pulmonary embolism produced bilateral massive intrarenal hematomas (pseudotumors). The role of radiologic investigation (nephrotomography, renal scan and selective high dose arteriography) was found to identify and localize the intrarenal hematomata and exclude underlying renal pathology. Although an abnormal kidney is more likely to bleed, this case presentation demonstrates that even carefully monitored anticoagulation within the therapeutic range can induce massive intrarenal hemorrhage in previously normal kidneys. The renal architecture returned to normal on late follow-up examination on simple conservative management.
