Pseudohypoparathyroidism-Associated Spinal Stenosis

STUDY DESIGN: Pseudohypoparathyroidism associated with disorders of the spine is rarely reported. In this report, the authors present a case of pseudohypoparathyroidism in a 41-year-old man who had narrow spinal canal and multiple disc herniation in the cervical spine. SUMMARY OF BACKGROUND DATA: The patient had progressive spastic tetraplegia due to cervical cord compression caused by multiple disc herniations at the C3-C4, C4-5, and C5-C6 levels in the developmentally narrow spinal canal. Based on the features of Albright's osteodystrophy, serum laboratory results, and an Ellsworth-Howard test, the diagnosis of pseudohypoparathyroidism, type I was confirmed. METHODS: The patient underwent expansive laminoplasty at C3 through C6 levels. RESULTS: His symptoms have gradually improved during the 1-year and 6-month periods after the surgery. CONCLUSIONS: A case of pseudohypoparathyroidism-associated spinal stenosis was reported.
