Giant Renal Angiomyolipoma: A Rare and Formidable Challenge: A Case Report

Renal angiomyolipoma (AML), also referred to as renal hamartoma, is a rare solid tumor without malignant characteristics. The inheritance pattern of renal AML is autosomal dominant. If the lesion grows to a large size, a series of clinical manifestations and serious complications may occur. We herein present a case of giant renal AML in a 49-year-old female patient, who presented with left-sided abdominal bloating for 1 month. Following abdominal ultrasound and computed tomography examination, the patient underwent total left nephrectomy. The resected mass was sized 18 × 15 × 11 cm. Postoperative histopathological examination confirmed the lesion as a giant renal AML. There are only few cases of giant renal AML (> 10 cm) reported in the literature to date. Due to the large size of the tumor, it is crucial to report similar cases, their diagnosis, and treatment.
