The case of a 43-year-old woman with a several month history of severe back pain is reported. CT and MR imaging revealed an intramedullary cystic tumor, which was considered a dermoid cyst or teratoma. During surgery, the tumor was found within the base of the filum terminale and completely resected. Microscopic studies revealed a mature teratoma with an intramural carcinoid nodule. Thirteen-mo...

Intramedullary spinal cord metastasis is very rare. In this study, we present the case of a 32-year-old male patient with a 2-month history of bilateral lower extremity weakness. Initial magnetic resonance imaging of the dorsal spine showed abnormal thickening of the dorsal spinal cord at the level of the T1-2 bodies. FDG-PET/CT images revealed a hypermetabolic lesion in the spinal cord at this...

Intraspinal epidermoid cyst is a rare tumor. The incidence in adults is lesser than 1% and in children lesser than 3%. Epidermoid cyst is predominantly seen at the dorsal spinal level. A large percentage of epidermoid cysts are intradural extramedullary. Intramedullary epidermal cysts are rarer, with about 70 cases reported in the literature. These may be congenital or acquired with known assoc...

BACKGROUND This study aims to introduce a novel technique in treating benign bone tumors of the proximal radius by elastic intramedullary nail fixation and iliac graft after tumor resection. METHOD In this retrospective case series, the treatment outcomes of 17 patients with benign bone tumor involving the proximal radius were reported from January 2010 to August 2014. All the patients receiv...

Intramedullary spinal cord metastases (ISCMs) are rare and account for 4-8.5% of central nervous system metastases. Only one case of biopsy-proven ISCM due to prostate cancer has previously been reported. The current study presents an additional unique case of a 74-year-old male who developed symptoms from an intramedullary conus medullaris metastasis as the first manifestation of prostate aden...

BACKGROUND Primary spinal cord intramedullary tumors are rare and present with insidious symptoms. Previous treatment protocols emphasized biopsy and radiation/chemotherapy but more aggressive protocols have emerged. OBJECTIVE To report our experience. METHOD Forty-eight patients were diagnosed with primary intramedullary tumors. The cervical cord was involved in 27% and thoracic in 42% of ...

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...

Intramedullary tumors affecting the entire cord from the cervicomedullary junction to the conus are termed "holocord tumors". Ependymomas are the most frequent intramedullary tumor in adults. Holocord ependymoma is an exceedingly rare condition. An extensive review of the literature revealed that only five other cases have been reported. We report the sixth case of holocord ependymoma. In this ...
