[Evaluation of Gd-DTPA enhanced MR in the diagnosis of the degeneration stage of cerebral cysticercosis].
OBJECTIVE
To detect the value of qualitative and orientating diagnosis in the degeneration stage of cerebral cysticercosis with Gd-DTPA enhanced MR.


METHODS
Sixty-nine cases of cerebral cysticercosis were diagnosed by enhanced MR as degeneration stage, and confirmed by immunological examination and/or by surgery. MR plain scanning was conducted for the same cases.


RESULTS
The plain scanning showed single or multiple lesions with long T1 and long T2 signals, and the enhanced scanning showed nodular or annular lesions. The diameter of the lesion after enhanced scan was not more than 22 mm with an average value of 8.1 mm. Some cases showed single lesion on plain scanning but showed multiple lesions after enhanced scan.


CONCLUSIONS
The enhanced MR shows more typical features of the degeneration stage cerebral cysticercosis. It can define the number, position and range of the lesions, and can improve the accuracy of differential diagnosis, and therefore be of importance in formulating treatment scheme and prognosis.
