Abstract |
We report three patients with adrenal pheochromocytoma who were associated with type I neurofibromatosis. Two of them were asymptomatic, but one case involved hypertension. We reviewed medical records and adrenal imaging, and estimated the prevalence of adrenal pheochromocytoma among neurofibromatosis type I patients in one university hospital in Korea. A total of 658 patients were coded for neurofibromatosis type I (Q85.0 with International Classification of Diseases 10 version) with clinical impression, but only 371 were confirmed via 1997 National Institute of Health criteria. Adrenal images were generated in 203 patients, and 3 of them were diagnosed with pheochromocytoma. According to the results of this study, the estimated prevalence of adrenal pheochromocytoma in type I neurofibromatosis was 0.30-1.48%. |
