A 66-year-old Lithuanian female patient with a history of hypertension was diagnosed with bilateral adrenal tumors during a routine sonoscopy. Scintigraphy with metaiodobenzylguanidine and computed tomography scan revealed right 130/116/93 mm and left 85/61/53 mm pheochromocytomas. The patient suffered from hypertension with blood pressure over 240/100 mm Hg and heartbeat disturbances. Blood adrenaline levels exceeded the norm 10-fold. After possible spread of tumors was rejected, laparoscopic transperitoneal adrenalectomy was planned in 2 stages, starting on the right then followed by the left side. After preoperative treatment with adrenoblockers, 2-stage bilateral laparoscopic adrenalectomy was performed. 13 cm × 12 cm × 9.5 cm right adrenal and, 3 months later, 8.5 cm × 8 cm × 6 cm left adrenal pheochromocytomas were removed. Histologically - radical extirpation, pheochromocytomas with possible malignant potential. Stable remission of hypertension was achieved postoperatively. Laparoscopic transperitoneal adrenalectomy is a safe and feasible method of treatment of large benign and possible malignant, but noninvasive pheochromocytomas.
