A Case of Spontaneous Perinephric Hematoma From Rivaroxaban.

ABSTRACT

Spontaneous perinephric hematoma is an uncommon but serious condition that is typically caused by tumor hemorrhage or vascular disease such as polyarteritis nodosa. We describe a 78-year-old Chinese gentleman with underlying chronic kidney disease, renal cysts, non-obstructive renal stones, hypertension, ischemic heart disease, and atrial fibrillation who was on rivaroxaban and clopidogrel. He developed spontaneous perinephric hematoma complicated by acute kidney injury, anemia, and myocardial infarction who underwent angioembolization and packed cell transfusion. He did not have further bleeding episodes, and his kidney function improved before discharge.
