Abstract
RATIONALE: The different variants of renal angiomyolipoma pose diagnostic and therapeutic challenges in clinical practice. We report a rare case of renal solid-cystic angiomyolipoma, with the aim of offering new insights into the preoperative imaging assessment of renal masses. PATIENT CONCERNS: A 72-year-old female was admitted to our hospital because of a solid-cystic mass discovered in her right kidney during an abdominal computed tomography scan at another hospital. Her medical history includes a 5-year history of hypertension treated with medication, as well as hepatic cysts and bilateral renal cysts. DIAGNOSES: The postoperative pathological diagnosis is renal solid-cystic angiomyolipoma. INTERVENTIONS: The solid-cystic mass in the right kidney was surgically removed via laparoscopic partial nephrectomy under general anesthesia. OUTCOMES: The patient had an uneventful recovery and was discharged on the second postoperative day without complications. LESSONS: Renal angiomyolipoma is usually easily distinguishable on imaging, but this case aims to alert clinicians to differentiate the rare variants of renal angiomyolipoma from other renal tumors. In the future, more cases are needed to summarize the characteristics of different variants of renal angiomyolipoma.
