title: Malignant intraosseous peripheral nerve sheath tumour of the proximal femur: a case report.
abstract: We report a rare case of an intraosseous malignant peripheral nerve sheath tumour of the femoral head and neck. The tumour presented as a well-defined radiolucent lesion on plain radiography. Computed tomography showed aggressive destruction of the bone with no involvement of the adjacent soft tissues. Magnetic resonance imaging revealed an isointense signal intensity on T1-weighted images, hyperintensity on T2-weighted images, and non-homogeneously increased signal intensity after administration of contrast media. The final diagnosis was based on pathohistologic analyses due to the non-specific nature of the lesion.
