Rare case of reninoma with double inferior vena cava.

摘要

A 16-year-old boy suffered from headaches and dizziness for 2 years. He was found to have remarkably elevated blood pressure (BP) of 180/110 mmHg. Laboratory findings showed a low level of serum potassium and markedly increased plasma renin activity. A solid mass at the periphery of the right kidney and double inferior vena cava (IVC) were detected by abdominal computer tomography (CT). Right partial nephrectomy via laparoscopy was performed on the patient. The histologic and electron microscopic findings comfirmed a diagnosis of juxtaglomerlar cell tumor. The patient had no headache or dizziness with normal BP after surgery.
