A 61-year-old man with idiopathic hypoparathyroidism presenting as spondylitis had a history of seizures and cataracts and developed a completely ankylosed spine. Biochemical studies were diagnostic of idiopathic hypoparathyroidism. Spinal roentgenograms showed paraspinal calcification as a cause of the ankylosis.
A search of the literature suggests this presentation may be common enough to warrant calcium and phosphorus determinations in individuals with spondylitis who have atypical clinical or roentgenographic features as well as in spondylitis developing in the elderly. Certain relationships are discussed pertaining to the heretofore rare association of soft tissue calcification in idiopathic hypoparathyroidism.
