摘要:

目的:探讨家族遗传性Fahr病的头颅CT表现及基因突变特点。方法:回顾性分析一家系3代4例患者的头颅CT表现
及基因突变特点,并结合文献对家族遗传性Fahr病进行探讨复习。结果:1例临床表现为行动迟缓伴记忆力下降、反应迟钝,
其余3例均无临床症状;4例患者头颅CT检查均提示双侧小脑齿状核、基底节区以及侧脑室旁对称性钙化灶;4例患者检测血
清甲状旁腺激素、甲状腺功能检查、钙、磷、镁均正常;3例患者基因检测SLC20A2 基因9号外显子1604位点G突变为A。结论:
依据家族史、头颅CT颅内钙化灶以及SLC20A2 基因检测结果,可明确诊断家族遗传性Fahr病。

Abstract:

Objective: To investigate the CT and gene mutation in familial hereditary Fahr's disease. Methods: Retrospective
analysis was done on cranial CT clinical manifestations and gene mutation characteristic of 4 patients in 3 generations of one family,
and combined with literature, family hereditary Fahr's disease was reviewed. Results: The clinical manifestations of 1 patient were
slow action, decreased memory and delayed response, while the other 3 patients had no clinical symptoms. The cranial CT findings of
all 4 patients showed symmetrical calcification in bilateral cerebellar dentate nucleus, basal ganglia and paraventricular regions; serum
parathyroid hormone, thyroid function, calcium, phosphorus and magnesium were normal in 4 patients; in 3 patients the G mutation of
the exon 1604 of SLC20A2 gene was A in gene detection. Conclusion: According to family history, cranial CT, intracranial
calcification and SLC20A2 gene test results, familial hereditary Fahr's disease can be diagnosed clearly.
