Spontaneous Bilateral Renal Subcapsular Hematoma as a Possible Complication of Myeloproliferative Disorders

Abstract

A 64-year-old male had bilateral renal subcapsular fluid accumulation evident on abdominal sonography performed during postoperative follow-up after surgery for a hepatoma. There were no clinical symptoms, and he had no history of trauma or receiving anticoagulant medication. Spontaneous bilateral renal subcapsular hemorrhage was diagnosed after a series of examinations. He did have an underlying myeloproliferative disorder (MPD), and had received incomplete cytoreductive treatment. Platelet aggregation in MPD is often abnormal, and both bleeding and hypercoagulation complications have been reported. Here we report a rare case of MPD with possible thrombohemorrhagic complications presenting as spontaneous bilateral renal subcapsular hematomas.
