Primary thoracic intramedullary spinal cord tumor with likely metastases of glial origin to the lumbosacral vertebrae: Illustrative case.

Background: Metastasis of systemic neoplasms to the spine is common; however, the metastasis of primary spinal cord tumors to other regions in the body is an infrequent occurrence. A few case reports have described the metastasis of primary spinal cord tumors, and in most cases, patients were younger than 30 years of age.

Case Description: We present an illustrative case of a 47-year-old female with metastatic lesions to the lumbosacral vertebrae years after the initial diagnosis of an intradural, intramedullary spinal cord tumor (IMSCT).

Ventriculoperitoneal shunt complications in an adult population: A comparison of various shunt designs to prevent overdrainage.

Background: Overdrainage after cerebrospinal fluid diversion remains a significant morbidity. The hydrostatic, gravitational force in the upright position can aggravate this. Siphon control (SC) mechanisms, as well as programmable and flow regulating devices, were developed to counteract this.

Intradural-extramedullary isolated compressive sarcoid lesion.

Background: Sarcoid involvement of the central nervous system is a rare occurrence, with involvement in approximately 5-10% of all cases. Isolated spinal involvement is an even rarer encounter, only 0.3-1% of all cases.
