Robot-Assisted Cortical-Sparing Adrenalectomy in a Patient with Von Hippel-Lindau Disease and Bilateral Pheochromocytomas Separated by 9 Years

Abstract

Von Hippel-Lindau disease is a heritable syndrome that confers an increased risk of developing various benign and malignant tumors to those with a germline mutation of the tumor suppressor gene. We present a case of a male patient who initially presented at age 9 with headaches, fevers, and fatigue. He was found to have a left pheochromocytoma which was successfully managed with open total adrenalectomy. He presented again at age 18 with a second pheochromocytoma in the right adrenal gland. DNA analysis revealed a de novo Val84Leu mutation in the Von Hippel-Lindau gene, not seen in either parent. The challenge presented was that of balancing the obvious benefits of cortical- sparing adrenalectomy with the risk of tumor recurrence in spared tissue. Ultimately, management consisted of a robot-assisted laparoscopic partial right adrenalectomy with successful preservation of adrenocortical function.
