Case report: bilateral adrenal pheochromocytoma.
|
| Abstract |
Pheochromocytoma remains a clinical challenge to diagnose and manage. In addition, the association of multiple endocrine neoplasia syndromes with pheochromocytoma require the clinician's awareness to evaluate patients with pheochromocytoma (especially when bilateral) for abnormalities in thyroidal C-cell function with serum calcitonin determinations. The authors present a case of a 42-year-old woman initially diagnosed with, and treated for, cranial artery vasculitis because she had a stroke and a history of rheumatoid arthritis and asthma. Subsequent evaluation of episodic blood pressure increases, headache, and tachycardia revealed biochemical evidence of catecholamine overproduction. Bilateral adrenal masses were found on computed tomography scanning, and the functional nature of the adrenal masses was confirmed by a meta-Iodobenzylguanidine scan. Upon further evaluation, an elevated serum calcitonin concentration was demonstrated, which increased greatly with pentagastrin stimulation. C-cell hyperplasia was demonstrated by subsequent thyroidectomy, confirming the diagnosis of multiple endocrine neoplasia 2A. The difficulty in arriving at a correct diagnosis, the subsequent management, including bilateral adrenalectomy and thyroidectomy, and newer insight into the genetic abnormalities of multiple endocrine neoplasia 2A are discussed.
