Anastomotic Renal Sinus Haemangioma—A Case Report

Vascular tumours of the kidney are a heterogeneous group of lesions showing common characteristics with malignant neoplasms, making it significantly challenging the pre-operative diagnosis. Among these lesions, anastomotic hemangioma (AH) is a recently recognised variant of hemangioma of the genito-urinary tract characterized by a complex vascular structure. In this case report, we present the case of an 85-year-old patient with an incidental diagnosis of renal mass. The multidisciplinary decision to proceed with nephrectomy, with subsequent benign histological result, highlights the uncertainty surrounding the preoperative evaluation of renal tumours This case highlights the importance of evaluation and multidisciplinary approach in the management of renal masses, particularly for rare lesions such as AH. Knowledge of these pathological entities is crucial for clinicians to avoid misdiagnosis and inappropriate treatment and to improve the quality of care in patients with renal tumours. Increasing awareness of these variants may also influence improvement in imaging strategies and diagnostic guidelines, promoting a more conservative approach in the presence of suspicious, but potentially benign, lesions.
