title: [A rare case of intramedullary epidermoid cyst diagnosed by MRI].
abstract: Intramedullary epidermoid cysts are rare entities. A case recently seen on MRI led us to review the literature on the subject. A 9 year old boy developed in a four month-time a spastic paraparesis with a T7-T8 sensitive level. The MRI showed a widening of the spinal cord at the T6 level with an area of decreased signal on T1 weighted images, and a homogeneous round shaped area of increased signal on T2 weighted images. The authors discuss the contribution of MRI to the diagnosis of this lesion. The number of cases of intramedullar epidermoid cysts, like dermoid cysts, diagnosed with this neuroradiological method, is still very limited and the literature only mentions isolated cases.
