Anastomosing hemangioma (AH) is a rare benign vascular lesion that primarily involves the genitourinary tract. Cases have also rarely been reported in other organs. AH is often discovered incidentally and resembles angiosarcoma histologically. On imaging, it may mimic other vascular lesions such as renal cell carcinoma and neuroendocrine tumors. We present a case of a 32-year-old woman with incidentally detected AH involving the kidneys, adrenal glands, liver, and retroperitoneum, initially presumed to be neuroendocrine tumors based on imaging findings on CT and 68Ga-DOTATATE PET scans.

Primary intrarenal hemangioma - A series of 39 cases.

Intrarenal hemangiomas lack concise clinicopathologic information, due to the predominance of single case reports and inclusion of other vascular neoplasms and hemangiomas of perirenal, hilar, and renal vein origin. Herein, in this multi-institutional study we evaluate clinicopathologic features of 39 intrarenal hemangiomas. The median age was 62 years (range = 27-94 years; 2:1 male to female ratio), with left-sided predominance (left = 21, right = 13; one case was bilateral).

Article Synopsis
- Hemangiomas are benign vascular tumors that primarily affect the skin and soft tissues, with anastomosing hemangioma (AH) being a specific subtype that mimics more serious conditions like angiosarcoma; there are fewer than 300 reported cases of renal hemangiomas.
- A case study of a 28-year-old male revealed a left renal mass identified during tests for abdominal pain, with subsequent imaging and surgery confirming the diagnosis of AH through histopathological analysis and specific immunohistochemical markers.
- Accurate diagnosis of AH is crucial to avoid unnecessary treatment and complications, highlighting the need for greater awareness and reporting in the medical community to enhance diagnostic accuracy and patient management.
