title: [Unilateral choreic movements in idiopathic hypoparathyroidism].
abstract: We report a patient with idiopathic hypoparathyroidism associated with unilateral calcification of the basal ganglia and contralateral choreic movements. A 66-year-old woman was admitted to our hospital because of involuntary movements of the left limbs. Two years before the present admission, she had operations for bilateral cataracts. Eight months before admission, she had an onset of severe carpal spasms and pain in both arms and legs. These symptoms improved after one month's rest in a hospital. About a month before admission, she noted progressive difficulty in using her left hand, followed by difficulty in walking due to the abnormal involuntary movement of the left lower limb. Two weeks before admission her carpal spasms appeared again, bilaterally. On admission, she was alert. The general physical examination was normal. Neurological examination revealed choreic movements in the left hand, arm, leg and neck, and grimacing of the left face. She also complained of the spasms and pain in her hands, dysarthria and shortness of the breath. Chvostek and Trousseau signs were positive. Laboratory examination revealed marked decrease in serum calcium level (2.57 mEq/ml) and increase in inorganic phosphorus level (6.40 mEq/ml). Serum level of parathyroid hormone was less than 10 pg/ml. Ellthworth-Howard test was positive, in that the infusion of parathyroid hormone (100 u) elicited a marked increment of the urinary excretions of phosphorus and cAMP. X-ray examination of the spine revealed ossification of the posterior longitudinal ligament in the cervical region. CT-scans of the brain revealed calcification in the region of right globus pallidus and putamen.(ABSTRACT TRUNCATED AT 250 WORDS)
