Abstract

Hemangiomas are rare, benign vascular neoplasms that are more common in patients with end-stage renal disease. Here, we describe 2 cases of hemangioma misdiagnosed as renal cell carcinoma before renal transplantation. The key finding in our case was the misdiagnosis of hemangiomas as renal cell carcinoma based on computed tomography and magnetic resonance imaging in patients with end-stage renal disease. Because living transplantation was planned for our patients, we performed rapid surgical resection of the heterogeneously enhancing renal masses to avoid delays in transplantation. Our case highlights the importance of rapid surgical resection of enhanced renal masses to confirm diagnosis, thereby avoiding delays in patients scheduled for renal transplantation.
