Distant Intradural Metastasis by Direct Seeding Through Dural Opening From the Metastasis of Rectal Cancer / 대한척추외과학회지

Few cases of intradural metastasis of a non-neurogenic origin, without antecedent cerebral metastasis, have been reported. To the best of our knowledge; however, this is the first reported case of distant tumor metastasis via seeding to the intradural space through a dural opening, which formed a tumor mass without antecedent brain metastasis at a different spine level. The medical records and imaging studies of a 67-year-old woman suffering from lower back pain and paresis of the lower extremities, were reviewed. She had previously had rectal cancer. A decompressive laminectomy and excision of the intradural mass were performed. The histopathology study confirmed her original diagnosis.
