[Progressive spinal muscular atrophy and parathyroid adenoma. Clinico-pathologic study of a case].
A 82 year-old man died 6 years after the onset of a progressive spinal muscular atrophy. Post-mortem examination disclosed a parathyroid adenoma. Weakness and wasting were prominent in the proximal lower limbs. There were no fasciculations. Involvement of the medulla was mild and late. These clinical features were also present in 16 reported cases, which were improved by treatment of primary or secondary hyperparathyroidism. Our patient differs by the involvement of the hand muscles and the loss of tendon reflexes. Neuropathological study, as in one other reported case, showed a loss of anterior horn cells. Such cases underline that calcium metabolism must be studied in syndromes of spinal muscular atrophy.
