It has been reported most commonly in the testes and genitourinary system [1-2], but it has also been described in the liver [3], gastrointestinal tract, ovary , and paraspinal region [4]. Although AH is well differentiated and has no malignant potential, it lacks specific imaging features and is therefore difficult to diagnose preoperatively. AH occurring in the liver is prone to be misdiagnosed as liver angiosarcoma [5]. Similarly, AH arising in the kidney is particularly difficult to distinguish from clear cell renal cell carcinoma, angiomyolipoma, and angiosarcoma, often leading to preoperative misdiagnosis. A 77-year-old woman was admitted to the Department of General Surgery with intermittent black stools for 20 days.After admission, she underwent an abdominal examination. Contrast-enhanced abdominal CT revealed a cystic lesion in the left renal sinus, approximately 2.0 cm \u00d7 2.0 cm in size. No significant enhancement was observed within the cyst on enhanced scanning, whereas nodular enhancement was visible in the cyst wall, raising the possibility of cystic renal carcinoma .laparoscopic radical nephrectomy was performed after exclusion of surgical contraindications. A diagnosis of anastomosing hemangioma of the kidney was made.<\/jats:p>","DOI":"10.3389\/fonc.2026.1767412","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T04:29:03Z","timestamp":1781843343000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Anastomosing
