SPINAL LEPTOMENINGEAL DISSEMINATION OF GL IOBLASTOMA

Leptomeningeal dissemination is not uncommon in the clinical course of malignant gliomas. We report on a patient who developed spinal sympto ms some months after treatment of a cerebral glioblastoma. On MRI, the re was a thickening and a subarachnoid enhancement of the spinal cord. Pathoanatomically, tumor recurrence and multiple dropping metastases were observed, infiltrating the spinal roots and compressing nerval st ructures. Conclusions: Leptomeningeal metastasis modifies the course o f disease. Diagnosis is facilitated by MRI. Prognosis mostly depends o n the extent of cerebral complications.
