background and importance: disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. even after the introduction of high-resolution magnetic resonance imaging (mri), it is still frequently misinterpreted as neoplastic masses. unfortunate...

An unusual case of intradural paragangliomas in the cauda equina region in a 29-year-old male is presented. The patient presented with signs and symptoms of raised intracranial pressure. The symptoms resolved after tumor resection.

STUDY DESIGN A retrospective clinical data analysis. OBJECTIVE To investigate the factors related to postoperative neurological deficits after nerve root resection in the treatment of spinal intradural schwannoma. SUMMARY OF BACKGROUND DATA Neurological deficits could be observed after resection of tumor-involved nerve roots in spinal intradural schwannoma. Thus, it is important to find the...

Objective: To observe the therapeutic effect of microsurgery through hemilaminectomy approach on extramedullary spinal tumor. Methods: Hemilaminectomy was performed on 45 patients with extramedullary spinal tumor. Of the 45 patients, 35 had intradural extramedullary spinal tumors and 10 dumbbell-shaped spinal tumors. Spinal schwannoma occurred in 36 patients and spinal meningioma in 9 patients....

A 51-year-old woman presented with a rare completely intradural and extramedullary spinal ganglioneuroma associated with multiple hamartoma syndrome and manifesting as complaints of neck pain and dizziness persisting for 8 months. Magnetic resonance imaging of the spinal cord revealed an intradural extramedullary lesion at the C1 level. She underwent right suboccipital craniectomy and C1-2 hemi...

The incidence of spinal meningioma is very rare in children. A 14-year-old girl presented with right arm weakness, gait disturbance, and urinary incontinence. Cervical magnetic resonance imaging revealed an intradural extramedullary tumor dorsal to the spinal cord in the level of C1. The tumor was totally removed despite the severe cord compression. Meningotheliomatous meningioma was diagnosed ...

BACKGROUND Dermoid tumors are slow growing, benign CNS lesions. CASE DESCRIPTION This case study concerns a 29-year-old female with a 6-year history of lower extremity paresthesias attributed to magnetic resonance (MR)/computed tomography (CT) documented intradural dermoid tumor that extended from L1 to S1. On MR, it was hypointense on T1, hyperintense on T2, and did not enhance with gadolini...

Results of stereotactic radiotherapy (SRT) for spinal intradural metastases developing inside or adjacent to the previous external-beam radiation therapy (EBRT) field are shown in 3 cases. One case of spinal intramedullary metastasis and two cases of intradural extramedullary metastases were treated using a Novalis shaped-beam SRT. Case 1 developed an intramedullary metastatic tumor in the C1 s...

We tested the hypothesis that 5 cm H2O of positive end-expiratory pressure (PEEP) reduces the incidence of pneumocephalus in patients who undergo spinal intradural tumor surgery. Fifty-three ASA I to III patients who underwent thoracolumbar intradural tumor surgery between the years 2003 and 2006 were included in this study. All patients received propofol, fentanyl, and cisatracurium for induct...

We present a rare case of skull base chordoma of extraosseous intradural type that presented as acute intratumoral hemorrhage. Surgical removal of the tumor was accomplished using a skull base approach.
