[Spinal cord involvement revealing systemic sarcoidosis].
Spinal neurosarcoidosis is rare (0.43 p. 100 of all sarcoidosis) and can be the initial manifestation of the disease. A 43-year-old right handed African man developed a progressive dorsal neck pain, slowly worsened paresthesia weakness in the legs and a gait disturbance. Magnetic resonance imaging (MRI) scan of the cervical and thoracic spinal cord (sagittal T(1)- weighted image) revealed diffuse enlargement of the cord from C2 to T7 with intense intramedullary enhancement from C2 to T3 after administration of contrast material on sagittal T(1)- weighted image. Cranial MRI scan was normal. Radiographs of the chest revealed bilateral symmetric hilar mediastinal lymphadenopathy with no pulmonary infiltrates. Bronchial biopsy demonstrated non caseating granulomas with langerhans giant cells. The serum angiotensin converting enzyme level was elevated. The patient received corticosteroid with good progressive response. His neurologic symptoms improved markedly and twenty months post-treatment MRI showed no abnormality on enhanced T(1)- weighted images. Two years later he had no relapse. Only 6 to 10 p. 100 of patients with neurosarcoidosis have spinal cord involvement, which may account for the first clinical manifestation of the disease. Most patients with neurosarcoidosis have associated extraneurologic abnormalities. The diagnosis is supported usually by extraneurologic biopsies. Spinal cord biopsy needs to be considered on case-by-case basis.
