摘要
目的探讨假性甲状旁腺功能减退症颅内钙化特点及其诊断价值。方法回顾分析4例假性甲状旁腺功能减退症临床表现、实验室检查及头部CT颅内钙化特征。结果大脑基底节钙化以壳核钙化最早、范围最广和程度最重 ,典型呈“倒八字”征和大脑皮层下区对称性“星火样”钙化是本病颅内钙化特征。结论头部CT扫描能正确反映本病颅内钙化部位、范围和程度 ,壳核“倒八字”征钙化和大脑皮层下区对称性“星火样”钙化是重要影像特征 ,并对了解病变程度。
Objective To study the character of cranial calcification in pseudoly poparatly roidisim and its diagnostic value.Methods The clinical manifestation?examination of laboratory and the character of cranial calcification of CT scan in 4 cases of pseudoly poparatly roidisim were analyzed retrospectively.Results The calcification of crustal core is the earliest?widest and seriousest in that of basal ganglion.The calcification presented as inverse'八'sign in crustal core and starlike in subcortical region, which is the typical sign of pseudoly poparatly roidism.Conclusion CT could reflect correctly the location extension and degree of cranial calcification.The inverse'八' sign in crustal core and the symmetrical starlike calcification are the important image sign of pseudoly poparatly roidisim.And it is important to realize the degree?development and prognosis of the disease.
