Abstract
Objective To investigate the CT and MRI characteristics of chronic expanding intracerehral hematoma ( CEICH ) . Methods The CT and MRI findings of 5 patients with CEICH confirmed by surgery were retrospectively analyzed. Results The CT scan showed quasi - circular or ellipse lesions with clear borders in all the 5 cases, low density or density of lesions in the center with low density well - defined edematous hoop in 2 cases, and mass effect for all the 5 cases. The enhanced CT scan showed that the hoop was slightly enhanced in 2 cases, and intermediately enhanced in 3 cases. MRI scan showed that all the 5 cases got cystic lesions of heterogeneous high signal on T1WI and T2WI, with " hoop sign" of the cystic wall of low signal on T2WI, and SWI showed a lower signal of the " hoop" . And the enhanced scan revealed a intensified hoop. Conclusion The CEICH is lack of characteristic in CT imaging, however, it has a special " hoop sign" in MRI. So MRI is an ideal examination for CEICH.关键词
