Cystic pheochromocytomas are uncommon. Patients with cystic pheochromocytomas are more likely to be asymptomatic and to have a negative biochemical evaluation than those with classic solid tumors, which may lead to misdiagnosis. We describe herein a case of cystic pheochromocytoma that was discovered as an adrenal incidentaloma. The patient did not have any major symptoms, apart from occasional mild headaches and palpitations at night. Pheochromocytomas should be considered in the differential diagnosis of cystic adrenal lesions.
