It is well known that patients with pseudo (PHP)- and idiopathic (IHP) hypoparathyroidism are frequently associated with intracranial calcifications. The relative sensitivity of computed tomography (CT) and conventional skull radiography in detecting basal ganglia calcifications was studied in two patients with PHP and six with IHP. CT was more sensitive: the detection rate was 71% (5/7) for CT and 14% (1/7) for skull radiography. Furthermore, patients with more prolonged hypocalcemia showed a higher incidence of calcifications. Thus, CT was useful as a diagnostic technique in the early detection of calcified basal ganglia.
众所周知，假性（PHP）和特发性（IHP）甲状旁腺功能减退症患者常伴有颅内钙化。对2例PHP患者和6例IHP患者进行了计算机断层扫描（CT）和传统颅骨X线摄影检测基底节钙化的相对敏感性研究。CT更敏感：CT的检出率为71%（5/7），颅骨X线摄影的检出率为14%（1/7）。此外，低钙血症持续时间较长的患者钙化发生率更高。因此，CT作为一种诊断技术，在早期检测基底节钙化方面很有用。
