Cavernous Hemangioma of Ureter Masquerading as Malignancy – A Rare Case Report

Abstract

Hemangiomas of the genitourinary tract are rare. They may be clinically silent or present with profuse or recurrent hematuria. They result from embryological remains of unipotent angioblastic cells that show anomalous development within the blood vessels. They can be single or multiple. Multiple hemangiomas are called cutaneous angiomatosis, occurring in the setting of genetic disorders such as Klippel–Trenaunay syndrome or Sturge–Weber syndrome. Careful correlation between the clinical, radiological, and histological findings may help in avoiding unnecessary radical procedures. Here, we present a case of cavernous hemangioma occurring in the proximal ureter, causing hydronephrosis and posing a diagnostic challenge.
