Pheochromocytoma in Multiple Endocrine Adenomatosis

Abstract

PHEOCHROMOCYTOMA is an integral part of the multiple endocrine adenomatosis type II (MEA II) and has been reported in patients with multiple endocrine adenomatosis type I (MEA I).¹The clinical diagnosis of pheochromocytoma may not be suspected in these patients, since they are often normotensive and may have normal biochemical study results.^2,3Yet the detection of pheochromocytoma in patients with MEA syndromes is important, since surgery for associated tumors may precipitate hypertensive crises.³Computed tomography (CT) is an imaging modality that can noninvasively detect adrenal tumors with a high degree of accuracy.⁴The purpose of this communication is to discuss the role of CT in the detection of pheochromocytoma in patients with MEA syndromes. <h3>Report of Cases</h3><h3>Case 1.—</h3> A 38-year-old woman with a 17-year history of metastatic medullary thyroid carcinoma complained of a recent onset of pulsatile headaches. These episodes lasted two to three minutes
