Metachronous spinal metastases from supratentorial anaplastic astrocytoma

Leptomeningeal spinal metastases from supratentorial high-grade glioma are relatively rare. Authors report an unusual case of metachronous, symptomatic, dual spinal drop metastases in a 20-year-old male patient who was operated for right insular anaplastic astrocytoma 20 months earlier. Surgical decompression of the symptomatic D11-L2 drop metastasis was carried out. Histo-pathological examination revealed features suggestive of glioblastoma multiforme. Patient was advised postoperative radiotherapy. The pertinent literature is reviewed regarding this uncommon entity.
