Introduction: Anastomosing hemangioma in the adrenal area is extremely rare. We report a large anastomosing hemangioma in the adrenal area that underwent robot-assisted adrenalectomy.
Case presentation: A 49-year-old man with left back pain underwent magnetic resonance imaging (MRI) that revealed a tumor in the left adrenal area; it was diagnosed as nonfunctional endocrinologically. However, the major axis of the tumor increased from 64 to 72 mm during the 4-month period. Robot-assisted left adrenalectomy was performed. Although the large tumor adhered to the surrounding tissues, it was safely resected by the effective use of an extra robotic arm. An anastomosing hemangioma was diagnosed since there were no malignant findings.
Conclusion: Robotic surgical systems may serve as an effective treatment option for large adrenal tumors, and our report is the first robot-assisted adrenalectomy performed on an anastomosing hemangioma.
