Intramedullary spinal cord metastases: review of the literature.
OBJECTIVE
To review the epidemiology, dissemination, clinical presentation, diagnosis, treatment, survival and functional outcome of intramedullary spinal cord metastases (ISCM).


METHODS
Literature review of all surgically treated cases of ISCM and all described cases of ISCM of breast carcinoma.


RESULTS
42 references to 87 surgically treated cases of ISCM were found, 13 references to 27 cases with diagnosed and treated ISCM of breast carcinoma. In only 9 cases of spinal cord metastases of breast cancer was surgical resection of ISCM done (10% of all surgically treated ISCM).


CONCLUSIONS
Three treatment modalities are available for ISCM: radiotherapy, chemotherapy, and surgery. The gold standard remains radiotherapy. Microsurgical resection of a focal intramedullary mass appears to be feasible and should be considered in selected cases. Patients who have no evidence of widespread organ metastases or multiple intramedullary lesions and who have a life expectancy of at least a few months with tumours of non-lymphoma histology should be considered for tumor resection. In conclusion, ISCM are difficult to treat lesions, but early diagnosis, careful surgical management and maintenance therapy may substantially contribute to a satisfactory functional outcome and prolonged survival.
