Hanqiu Liu PhD, Presenter: Nothing to Disclose

To detect the characteristic MRI appearance of the tumoral form of cerebral schistosomiasis and its clinical value through analyzing the MRI features and post surgery pathological findings.

MRI features of the cerebral schistosomiasis in 20 patients,pathologically ( n = 6) or clinically( n = 14) proved cases were analyzed retrospectively ,and compared with the post-surgery pathological findings in 6 cases.

Single clustered lesions were found in 5 cases (5/ 20) ,and multiple clustered lesions in 15 cases(15/ 20) , amounting to 32 clustered lesions. nineteen clustered lesions (19/ 32) were located in right cerebral hemisphere ,including frontal lobe ( n = 3) ,frontoparietal lobe ( n = 6) ,and occipitoparietal lobe ( n = 10) ;10 lesions (10/ 32) in left cerebral hemisphere ,including frontal lobe ( n = 2) ,frontoparietal lobe( n = 3) ,and occipitoparietal lobe ( n = 5) ;3 lesions(3/32) in cerebellum. The nodular lesions were isointense with the gray mass like“island”,and 16 cases (16/ 20) show the“gigantic hand”form of edma around them. After IV administration of Gd-DTPA ,20 cases (20/ 20) revealed intensely enhancing nodules clustered,1-3 mm in diameter ,distributed along the enhancing pia mater adjacent on the surface of the brain or between the fissure ,which like bundles of grape.

The MRI enhancing appearance of the tumoral form of cerebral schistosomiasis is characteristic ,especially the enhancing nodules clustered, companying with the enhancing pia mater adjacent , which like bundles of grape; at the same time, it is very valuable to diagnosis this diease.

MRI is the most valuable tool to diagnose the tumoral form of cerebral schistosomiasis without injury
