STUDY DESIGN A retrospective analysis of a prospective database. OBJECTIVE To compare preoperative symptoms, ambulatory ability, intraoperative spinal cord monitoring, and pathologic cell proliferation activity between intramedullary only and intramedullary plus extramedullary hemangioblastomas, with the goal of determining the optimal timing for surgery. METHODS The subjects were 28 patien...

clear cell variant of ependymoma is almost exclusively located in the supratentorial region. only few cases of this tumor that located in the spinal cord have been reported. here we report one case of intramedullary clear cell ependymoma of the lumbar spinal cord. in microscopic examination, the tumor cells were round to oval with moderate amounts of clear cytoplasm and centrally located large ...

Tuberculosis of the central nervous system accounts for approximately 1% of all cases of tuberculosis and 50% of these involve the spine. Intramedullary involvement is rare in tuberculosis. Clinical presentation of spinal intramedullary tuberculosis (SIMT) is similar to intramedullary spinal cord tumor. Here, we report the case of a 49-year-old female with dull aching pain of both upper limbs o...

Background: This paper describes the establishment of a rat intramedullary spinal cord tumor (IMSCT) model and histopathological characterization of the tumor model. Methods: Fourteen male Wistar rats were randomized into two groups. The rats in group 1 (control group, n = 7) received a 5 μl intramedullary injection of serum physiologic (SF). Those in group 2 (experimental group, n= 7) received...

A 31-year-old man presented with a 3-year history of progressive weakness and paresthesias of both legs. Spinal MRI revealed a 10-cm intraspinal tumor at T1-T5 with syringomyelia on both ends (figure, A–C). Surgery successfully resected the intramedullary tumor grossly (figure, D and E). Pathology suggested the diagnosis of solitary fibrous tumor (figure, F–P). Intramedullary solitary fibrous t...

BACKGROUND AND PURPOSE Most intramedullary astrocytomas have been known to exhibit at least some enhancement on MR imaging regardless of cell type or tumor grade. The purpose of this study was to evaluate the incidence of nonenhancing intramedullary astrocytomas through a retrospective study within our institutions and a systematic review of the medical literature. MATERIALS AND METHODS A tot...

Background & Importance: Acute autonomic system impairment can be dangerous and life-threatening, and a clinician should be aware of its occurrence possibility. According to the anatomy of this system, spinal cord lesions could disturb its function. There are many reports of autonomic dysreflexia in spinal cord i njuries especially spinal cord trauma. Case Presentation: A 28 year-o...

A 63-year-old man with right hemiparesis was found (on MRI) to have an expansive intramedullary tumorous lesion at the C2-C3 level. After complete neurosurgical tumor resection, the tumor was histologically categorized as an intermediate grade of intramedullary melanocytoma, an uncommon neoplasm. Based on this peculiar case and review of the literature, radical surgical resection appears to be ...

BACKGROUND AND PURPOSE Because intramedullary spinal cord metastasis is often a difficult diagnosis to make, our purpose was to perform a systematic review of the MR imaging and relevant baseline clinical features of intramedullary spinal cord metastases in a large series. MATERIALS AND METHODS Consecutive patients with intramedullary spinal cord metastasis with available pretreatment digital...

Solitary fibrous tumor is rare benign mesenchymal neoplasm. The spinal solitary fibrous tumor is extremely rare. The authors experienced a case of intramedullary solitary fibrous tumor of cervicothoracic spinal cord in a 48-year-old man with right lower extremity sensory disturbance. Spinal MRI showed intradural mass lesion in the level of C7-T1, the margin between the spinal cord and tumor was...
