Incidentaloma suprarrenal asociado a normetanefrina urinaria elevada en un paciente hipertenso

OBJECTIVES To report one case of adrenal incidentaloma and to review the sensitivity and specificity of urine methanephrines in the diagnosis of pheochromocytoma. METHODS We report the case of a patient with high blood pressure and a left adrenal incidentaloma. Surgical excision of the mass was indicated after elevated urine methanephrine. RESULTS Pathologic study of the nodule established the diagnosis of cortical adenoma. CONCLUSIONS The elevation of urine normethanephrine is a non-specific parameter for the diagnosis of pheochromocytoma.
