摘要
目的：通过外伤后癫痫病人的ＣＴ、手术所见及病理变化的了解，对今后外伤性癫痫病人手术起指导作用。方法：对近１０年来４０例外伤后癫痫病人，再手术所见与ＣＴ、病理变化进行对比。结果：ＣＴ“脑软化”是外伤后癫痫－－脑膜脑瘢痕形成，它与缺血感染引起脑软化不同。结论：外伤性癫痫是顽固性。
Forty patients of posttraumatic epilepsy were documented by authours CT, Operative and pathologic demonstrate that epilepsy caued of intracerebral ciatrix Before operation all patierts were diagnosed as partial cerebral softening based on CT images The main CT findings included intracerebral hypodense areas in all patients and negative mass effect in 12 patients In 30 patients the lesions grossly were dearly whitish fibrotic tissue on operation In 35 patients who had pathologic study, Various degrees, of fibrous tissue proliferation were seen under microscope Although fibrous tissue was obvious, the lesion, still manifested as hypodense areas on CT image The degree of fibrosis could not be distinguished by density The negative mass effect was more pronounced on CT image, with more abundant fibrous tissue being present The development of pathological process of cicatrix and CT manifestation was also analyzed
