title: A case of primary leptomeningeal gliomatosis confined to the spinal cord.
abstract: We report a case of primary leptomeningeal gliomatosis limited to the spinal cord occurring in a 52 years-old patient, who presented with back pain and leg weakness. MRI-scan of the craniospinal axis revealed an enhancing cervicothoracic lesion confined to the leptomeninges. A diagnostic biopsy was taken followed by a six level cervicothoracic laminoplasty with the aim of debulking of the dorsal portion of the tumour and relieving cord compression. Two weeks following surgery, the patient developed bilateral arm weakness. Repeat imaging revealed extension of the lesion to the level of the lower medulla. This patient underwent spinal radiotherapy and concomitant chemotherapy with Temozolomide, but she died of pneumonia 8.5 months after the time of diagnosis. No post-mortem was performed. Primary leptomeningeal gliomatosis exclusively involving the spinal cord is an extremely rare condition bearing a dismal prognosis. It can be suspected on neuroimaging, but histopathological examination is required for the final diagnosis. No current treatment protocols are available. Decompressive surgery may have a role in relieving symptoms, but no substantial benefit has been proven in administering radio-chemotherapy.
