title: Inflammatory myofibroblastic tumour of the spinal cord: case report and review of the literature.
abstract: Inflammatory myofibroblastic tumours (IMT), also called inflammatory pseudotumours, nodular lymphoid hyperplasia, plasma-cell granuloma and fibrous xanthoma, are rare soft-tissue lesions characterised by inflammatory cells and a fibrous stroma. Clinically and radiologically, they may look like malignant tumours. They rarely affect the central nervous system and are very rare in the spinal cord. We report an IMT of the spinal cord in a 22-year-old woman presenting with spinal cord compression and a cauda equina syndrome. MRI showed a lesion at T9 with extramedullary and intramedullary components giving low signal on T2-weighted images and enhancing homogeneously. Pial lesions on the lumbar enlargement and thoracic spinal were present 11 months after surgery, when the lesion recurred. We present the radiological, operative and pathological findings and review the literature.
