ABSTRACT
Objective To analyze the DWI characteristics of intracranial epidermoid cyst (ECs),and to evaluate “T2 shine-through” effect. Methods There were 15 cases of ECs confirmed by pathology, in which 3 cases had the residual tumor after surgery. The ADC value was measured in ECs,deep white matter and CSF,and the comparison was made between DWI and FLAIR in showing the tumors. Results (1) The lesions in 15 cases were high intensity on DWI, their ADC value was from 0.80?10 -3mm2/s to 1.23?10 -3mm2/s, the average was (1.05?0.14)?10 -3mm2/s. But the ADC value of deep white matter was from 0.74?10 -3mm2/s to 1.09?10 -3mm2/s, the mean was (0.88?0.09)?10 -3mm2/s. The ADC value of CSF was from 2.98?10 -3mm2/s to 3.78?10 -3mm2/s,the mean was (3.31?0.21)?10 -3mm2/s. The ADC value of ECs was significant lower than that of CSF ( P
