Posterolateral sulcus (PLS) approach of the spinal cord, being equivalent to the dorsal root entry zone myelotomy, may offer the satisfactory exposure of the spinal intramedullary tumor if applied appropriately. Eight consecutive patients with spinal intramedullary tumors of lateral location underwent the surgery of PLS approach in our institute. There were 6 male and 2 female patients, ranging...

The clinical data and imaging studies of 12 patients with intramedullary metastases were reviewed retrospectively to see if these lesions had a typical radiographic appearance and to determine the sensitivity of the various radiologic examinations. The lesions were identified antemortem by either myelography, CT, MR, and/or intraoperative spinal sonography (IOSS). Final diagnosis was based on b...

Intramedullary spinal cord tumors, and more specifically ependymomas, are rare and can be a source of significantmorbidity for the patient. Resection of large spinal cord ependymomas may be associated with risks because of the extent of the manipulation of spinal cord parenchyma required to remove the tumor. Furthermore, large tumors often partially invade or adhere to the spinal cord, making t...

Osteochondromas are usually benign bone tumors found on the metaphysis of long bones. These tumors are rarely located on the spine especially at cervical level. This report presents the case of a 23-year-old man who had previously developed tetraparesis at the age of 13 after infectious myelitis. Recent severe clinical neurological deterioration revealed the diagnosis of osteochondroma arising ...

Hemangioblastomas are uncommon lesions that represent nearly 4% of the tumors of the spinal cord. Three fourths of them are sporadic, and the remainder are components of von Hippel Lindau (VHL) disease.1,2 They are mostly found in the cerebellum, although they can develop in the brain stem or spinal cord; of the latter, they are only rarely located in the filum terminale.3 The filum terminale i...

Intramedullary spinal cord metastasis (ISCM) is a rarely seen complication of cancer. We report a case of ISCM from gastric cancer. A 42-year-old male presented with a rare intramedullary spinal cord metastasis from gastric carcinoma manifesting as rapidly worsening motor and sphincter disturbances. The primary tumor had been treated 2 years previously. Magnetic resonance imaging (MRI) revealed...

Primary intracranial gliomas are a heterogeneous class of lesions that rarely metastasize. Even more infrequently, they may spread caudally into the spinal cord causing gliomatosis. In this case, we discuss an 18-year-old male patient with diagnosis grade IV astrocytoma gliomatosis, specifically detailing radiographic progression disease over 38 months. We also significance change in WHO classi...

Neuromyelitis optica (NMO) is an autoimmune disorder of the central nervous system, that predominantly affects the spinal cord and the optic nerve. Its key features include transverse myelitis, commonly associated with extensive inflammation spanning three or more consecutive vertebral segments. Longitudinal extensive spinal cord lesions can also occur in systemic autoimmune diseases, infection...
