OBJECTIVES/HYPOTHESIS To identify complex cases of tympanojugular paraganglioma (TJP) and to analyze their management and surgical outcome. To present strategy and guidelines on how to deal with the perioperative complicating factors. STUDY DESIGN Retrospective analysis. METHODS We retrospectively studied 212 TJP patients to identify the complex cases and analyzed their management and surgi...

Cavernous hemangioma in the spine is rare, and occurrence of intradural extramedullary cavernous particularly infrequent. A 57-year-old male patient visited emergency room with suddenly worsening neurological symptoms. Computed tomography at T10-11 levels showed a round isodense mass lesion, magnetic resonance imaging 1.2-cm oval mass. Therefore, diagnosis an tumor was suspected. Active subdura...

A 61-year-old woman with a very rare case of totally ossified large thoracic spinal metaplastic meningioma, showing progressing myelopathy is presented. Computed tomographic images showed a large totally ossfied intradural round mass occupying the spinal canal on T9-10 level. Magnetic resonance imaging revealed a large T9-10 intradural extramedullary mass that was hypointense to spinal cord on ...

Three cases of syringomyelia associated with intradural extramedullary tumors of the spinal canal are reported to demonstrate their radiographic feature, to postulate a mechanism for their formation, and to describe the clinical deterioration occurring in two patients immediately after metrizamide myelography. It is believed that the mechanism by which these syrinx cavities formed was similar t...

Intradural cement leakage after percutaneous vertebroplasty (PV) is a rare clinical picture. We report a 64-year-old woman with osteoporotic compression fracture of the L2 vertebral body developing monoparesis and monoparesthesia after PV. The diagnosis of intradural cement collection with spinal cord damage was evidenced by clinical and neuroradiographic investigation. After decompressive surg...

Paragangliomas of the cauda equina are rare neuroepithelial tumors, usually manifesting clinically as sciatica. Here, we report a case of cauda equina paraganglioma with an unusual course in a 43-year-old man. His main complaints were erectile and sphincter dysfunction. The low back pain was initially ascribed to accidental injury. Magnetic resonance imaging revealed intradural tumor at the L2/...

We report a case of central neurocytoma that manifested tumor recurrence with craniospinal dissemination. Imaging studies before surgery showed a markedly enhanced tumor with small cysts and calcification, which invaded the adjacent brain parenchyma, located in the posterior horn of the right lateral ventricle. Proton MR spectroscopy showed markedly elevated choline and lactate peaks with a str...

INTRODUCTION The aim of this study was to report surgical strategies and clinical outcomes for thoraco-lumbar intradural lipomas. Intraspinal lipomas are rare congenital histologically benign neoplasms, which account for less than 1% of all spinal cord tumors. These tumors are most frequently found in the lumbosacral area as components of a dysraphic state, however, intramedullary lipomas are n...

A previously healthy eighteen year old female presented with interscapular pain of 6 months duration. She also experienced progressive decline in her ability to perform fine motor skills such as handwriting as well as deficiency in coordination and motor strength. Imaging of the spine revealed a well demarcated intradural intramedullary lesion in the central portion of the cervical spinal cord....

Schwannomas are the most common intradural extramedullary tumors of the spine. They usually occupy a posterolateral or lateral position in relation to the cord. The ventral midline is a very rare location for the origin of a spinal schwannoma. A giant one in such a location causes technical difficulties in excision. Here, we present a giant cervical spinal schwannoma, located ventral to the cor...
