Abstract

Primary hyperparathyroidism (PHP) is a disease in which excessive amounts of parathyroid hormone (PTH) are secreted and calcium levels in the blood increase. Hypercalcemia caused by PHP has a major influence on the peripheral nervous system and produces symptoms such as muscle cramps, paresthesia, and proximal muscle weakness. Here we report a rare case of sensory-dominant polyneuropathy caused by PHP, which improved after surgery.

  Fig. 1. (A) Thyroid computed tomography shows a 12 × 9.97 × 6.65 mm enhanced nodule at the posterior aspect of the left thyroid lower pole. (B) Parathyroid metaiodobenzylguanidine scan shows a 1.3-cm soft-tisssue lesion with increased uptake of the radioactive tracer at the lower pole of the left thyroid gland (white arrow).
