Rara presentación de polineuropatía distal hipoglicémica causada por un insulinoma en el contexto de una neoplasia endocrina múltiple tipo 1

Multiple endocrine neoplasia type 1 is a rare disease. It is characterized by the neuroendocrine, parathyroid, pituitary, and enteropancreatic tumor involvement. We present the case of a 19 year old patient with symptoms of headache, convulsions and weakness of the four extremities. The presence of hypoglycemia 33mg/dL was confirmed. The electromyographic study showed motor sensory polyneuropathy in all four extremities. The abdominal magnetic resonance showed a tumor in the tail of the pancreas that after the pancreatectomy was confirmed as insulinoma. The glycemia was normalized. In addition, he presented a pituitary macroadenoma, primary hyperparathyroidism and non-functioning adrenal tumor. At 25 years of age, he presented severe headache and amaurosis of the right eye. Axial tomography showed a giant pituitary tumor and in the study of pathology chondroid malignancy (chordoma) was diagnosed.
