[Neurological complications in hyperparathyroidism].

The paper describes the clinico-instrumental diagnostic iter in a 57-year-old patient with amyotrophy of the pelvic and pectoral girdles and of the roots of the limbs, with lively and symmetric R.O.T., and without fasciculation, feeling deficit, bulbar involvement and pathological reflexes; EMG was probative for the neurogenic involvement of all four limbs, whereas muscular enzymes were normal. Laboratory controls showed primary hyperparathyroidism caused by a single operated parathyroid adenoma; other test enabled multiple endocrine adenomatosis to be excluded. The paper discusses the involvement of the nervous system during hyperparathyroidism paying special attention to spinal amyotrophy.
