Diagnosis: Neuroectodermal leptomeningeal carcinomatosis

Carcinomatosis meningitis of the leptomeninges in the spine usually arises from non-CNS tumors such as lung, breast, melanoma, or lymphoma. Some CNS tumors may seed the leptomeninges such as high grade astrocytoma, medulloblastoma, ependymoma, choroid plexus papilloma, and some pineal neoplasms. Intradural spinal metastases typically present as leptomeningeal involvement rather than intramedullary masses. Brain metastases are more commonly parenchymal. Other potential etiologies for diffuse spinal leptomeningeal enhancement include post operative change, meningitis, arachnoiditis, and sarcoidosis. Related Cases
