Abstract:
Objective To investigate how to diagnosis traumatic subdural effusion (TSE) and differentiate it with senile encephalatrophy in aged people by CT scan. Methods Fifty-two aged patients with TSE and 40 aged patients with encephalatrophy, admitted to our hospital from March 2008 to March 2010, were chosen in the study. Their clinical data and CT manifestations were retrospectively analyzed and compared. Results Fifty-two patients with TSE had 91 sites of the lesion, including 31 lesions located in temporal-frontal lobe and 30 lesions in frontal lobe. Among the 52 patients, 34 were also noted as having encephalatrophy. First-time CT demonstrated 32 patients with TSE, and the second-time CT on the left patients showed 20 having TSE too. Among the 52 patients, increasing amount of fluid in a short term was noted in 32 patients; local widened gyri with a flattened surface and narrowed sulci was presented in 30; "compressed arachnoid sign" was found in 9. CT results demonstrated that no above-mentioned manifestations were presented in patients with encephalatrophy.Conclusion For aged person, TSE is usually located in the temporal and frontal lobe, and should be differentiated with senile encephalatrophy. The key-points for differentiation include the location and the extent of changes of extra-cerebral space, the space-occupying signs as local flattened gyri and narrowed sulci, the appearing of "compressed arachnoid sign" and the changes of effusion in a short-term review.
