Abstract Type-1 neurofibromatosis (NF1) is a neurocutaneous syndrome classically known as peripheral NF to distinguish it from type-2 (central NF). Its main characteristic the high predisposition growth of multiple tumors, which specially arouses interest spinal surgeons due presence cord compression and deformities. Considering this, we have performed comprehensive review, with illustrative ca...

a retrospective analysis was performed on forty cases of spinal cord meningiomas, operated on at dr. shariati hospital from 1976 to 1990. age and sex distribution, clinical presentation and tumor location were comparable to those reported by others. in males the tumors were distributed evenly in cervical and dorsal areas and were often anterior to the cord. this finding makes a different surgic...

Characteristics of spinal cord gliomas Spinal cord gliomas comprised 20% of intraspinal tumors of all types in a large surgical series (Table 1) [1]. These tumors share several characteristics with cerebral gliomas. Spinal gliomas use the same histopathological classi®cation as gliomas of the cerebral hemispheres, such as astrocytoma and ependymoma. Determination of tumor grade is useful in pre...

BACKGROUND: Tumours form an integral part of disease process affecting the CNS and constitute a major part of all intracranial space occupying lesions. AIM: To study the histological findings of CNS tumors and to classify them according to WHO classification. MATERIALS AND METHODS: This is a five year study in which all the specimens of tumors of brain and spinal cord received in the department...

STUDY DESIGN Segmental arteries were interrupted bilaterally at up to three levels to study the influence on spinal cord blood flow (SCBF) and function in dogs. OBJECTIVES Considering the need to limit blood loss during surgery for spinal tumors, such as total en bloc spondylectomy, we studied the SCBF and function after experimental interruption of segmental arteries at up to three levels. ...

OBJECTIVE To reduce the risk of postoperative spinal instability or deformity, unilateral laminectomy (UL) has been recommended to remove spinal space-occupying lesions. The purpose of this study was to determine whether there were any advantages of UL for removal of spinal cord tumors. METHODS From May 1995 to May 2010, 94 patients with spinal cord tumors, who underwent tumor removal via UL ...

STUDY DESIGN Retrospective study MR images for spinal cord tumors. PURPOSE To analyze the characteristics of MR images for spinal cord tumors, which were then verified at surgery or biopsy. OVERVIEW OF LITERATURE MR images are often used as the primary diagnostic imaging tool and the preoperative study of choice. The need for biopsy may be obviated because of increasingly accurate preoperat...

ependymomas are glial tumors originate from ependymal cells lining the ventricles and the central canal of the spinal cord. two thirds of ependymomas arise in the infratentorial or intraventriclesandone-third aredetected in supratentorial area. however supratentorial “cortical” ependymomas are veryuncommon. ependymomas are usually infratentorial, intraventricular tumor, including 2–9% of all ce...

OBJECTIVE To compare the age distribution and characteristic MR imaging findings of ependymoma for each typical location within the neuraxis. MATERIALS AND METHODS During a recent eleven-year period, MR images of 61 patients with histologically proven ependymomas were obtained and retrospectively reviewed in terms of incidence, peak age, location, size, signal intensity, the presence or absen...
