Intradural extramedullary spinal metastasis from an ovarian carcinoma.

ABSTRACT

Intradural extramedullary metastases from tumours are a rare occurrence, accounting for less than 2 percent of all spinal metastases. We report a patient who presented with progressive paraparesis one and a half years after being operated for an poorly differentiated serous cystadenocarcinoma. Tumour mass decompression was carried out and the intradural tumour metastasis was removed. Histopathology revealed an identical appearance to the original ovarian tumour. This is the first reported case of an intradural extramedullary metastasis from a poorly differentiated serous cystadenocarcinoma of the ovary.
