Surgical removal is the standard of care for adrenal tumors greater than 2.0 cm diameter. For tumors smaller than 2.0 cm, imaging techniques evaluating patterns of contrast washout may offer a promising avenue for early identification of adrenal malignancy. Pretreatment of pheochromocytoma with phenoxybenzamine is associated with reduced surgical mortality risk. Surgical technique can be laparoscopic or open, depending on tumor anatomy and the experience of the surgeon. Vascular invasion is a contraindication for a laparoscopic technique. This review provides a summary of minimally invasive and open adrenalectomy techniques, including a discussion of management of vascular invasion and partial cavectomy.
