Computed tomography of cerebrovascular calcifications in postsurgical hypoparathyroidism.

Despite the extensive literature on the radiographic appearance of basal ganglia calcification in hypoparathyroidism, the vascular and perivascular deposits that are the hallmark of this disease have not been described radiographically. We report two patients with postsurgical hypoparathyroidism in whom such vascular calcification was observed on CT and was confirmed pathologically in one. The metabolic disturbance leading to the vascular deposits is discussed.
