ABSTRACT

Objective To investigate the clinical and CT characteristics of metastatic brain carcinoma and the differential diagnosis with other intracranial lesions and promote diagnostic level one step more,and to diminish misdiagnosis.Methods 106 cases metastatic brain tumor confirmed by CT and other methods in our hospital from 1990 to 2005 were retrospectively studied about clinical appearance and the relationship with anatomy and physiology,characteristics of CT and the main point of differential diagnosis.Results Metastatic brain carcinoma mainly could be devided to three following types based on clinical expressions,among them,apoplexic type dominated 46 cases(43.4%),epileptic type 26 cases(24.5%),brain tumor type 24 cases(21.6%),the clinical expressions correlated to anatomy and phyiology of lesion in each type,CT plain scan most appeared low density or equal density space occupying enhanced CT scan foci showed different degree stronger in lesion,and characteristic of perifocal edema.Conclusion The clinical appearance of brain metastatic carcinoma is various,easily misdiagnosed in early stage,looking for the primary tumor is the rather important diagnostic dependencies,enhanced CT scan is an important diagnostic method.
