Surgical management of intramedullary spinal cord metastasis: Report of three cases that revealed unknown malignancies

Intramedullary spinal cord metastasis (IMSCM) is a rare complication of malignancies still studied by case reports; although surgery is related with the best results, the management is still debated considering the risks and the low life expectancy; in fact, many authors prefer conservative management (radiotherapy, chemotherapy), and so less than 200 cases reported in the literature with patients IMSCM were treated surgically; reporting such cases will help to understand the pathology and elaborate a clear management protocol. We report three cases of IMSCM operated at our department; in those patients, the intramedullary lesions revealed the primary tumours.
