Case Report: Two highly unusual adrenal tumors presenting with hypertension: a giant cystic pheochromocytoma with an ipsilateral large renal parapelvic cyst and a giant adrenal myelolipoma

To our knowledge, our case of giant cystic pheochromocytoma accompanied by ipsilateral large renal parapelvic cyst, which is the first in the literature, reports the management of severe hypotension in the perioperative period and severe orthostatic dizziness in the two-month follow-up. Non-functional adrenal myelolipomas can cause hypertension with mass effect. Our second case is one of the largest adrenal myelolipomas in literature. Although surgical removal of giant masses is difficult, successful surgeries have resulted in resolution of hypertension in our cases at mid-term follow-up.
