Incidental finding of bilateral renal and adrenal anastomosing hemangiomas: A rare case report

Anastomosing hemangiomas are rare variants of vascular tumors found in adrenal, hepatic, and gastrointestinal tissue. Frequently, renal anastomosing hemangiomas are misdiagnosed on computed tomography (CT) as kidney cancers, resulting in unnecessary workups and detrimental treatments. We present a rare case of bilateral renal and adrenal anastomosing hemangioma found incidentally on renal biopsy. Patient is a 39 year-old African American male on hemodialysis with a history of end-stage renal disease secondary to lupus who presented with acute pericarditis and worsening renal insufficiency.
