To the Editor.—
We report an unusual case in which parathyroid adenoma and Guillain-Barré syndrome simmultaneously occurred.
Report of a Case.—
A 68-year-old woman was hospitalized two days after the onset of paresthesia in the extremities. A respiratory tract infection had occurred four weeks earlier. Examination disclosed an incomplete symmetrical motor deficit of the four limbs with slight distal predominance, without objective sensory disturbance. Stretch reflexes were reduced. Within 24 hours, the cranial nerves were affected, and the patient's breathing became so seriously impaired that she underwent a tracheotomy. Two days after admission, CSF analysis showed one lymphocyte per cubic millimeter with a protein level of 64 mg/dL. Nerve conduction velocities were sharply reduced. Results of routine blood chemistry studies were normal except for the serum calcium level, which was 145 mg/L. The serum phosphorus level was below normal, while calciuria and phosphaturia levels were high. The parathyroid hormone concentration
