Glial tumors are the largest group of central nervous system tumors and
glioblastoma multiforme is the most common form. Glioblastomas are
anaplastic forms of gliomas. Their high incidence and malignity have led
researchers to work hard to better understand and treat these tumors. It is now
know...

Two human malignant glial cell lines, U-251 and NMCG-I were used in this study.
NMCG-I cell lines were been established from an astrocytoma, grade III by our clinic.
Glial cells secrete platelet-derived growth factor (PDGF) - like molecules that stimulate
their own growth in an autocrine manner. ...

Extra-axial cavernous sinus hemangiomas are rare and represent 3% of all
benign cavernous sinus tumors. Total removal of cavernous sinus hemangiomas
is difficult due to the risk of severe intraoperative bleeding and the complicated
neurovascular structures of the cavernous sinus. These lesions ha...
Lumbar spinal extradural arachnoid cysts are rare, expanding lesions and they
commonly occur in the thoracic spine and lie posterolaterally. Their
pathogenesis is still unclear and it is claimed that arachnoid cysts are the result
of a widening of the septum posticum. The mechanism of cyst enlarg...

Brain metastasis is an uncommon and morbid complication of thyroid
carcinoma, especially follicular carcinoma. Because of its rarity, management is
still debated.
A 64-year-old woman presented with signs of blindness. After
ophthalmological and radiological evaluations, A frontobasal mass lesion...
INTRODUCTION: Meningiomas originate from meningothelial cells.
Meningioma is a common neoplasm in the CNS, representing about 15-20
percent of all primary intracranial tumors. Although malignant forms may
spread via blood, lymphatic drainage and cerebrospinal fluid to distant sites,
metastasis f...

Pleomorphic adenoma is the most common epithelial tumors of the human
lacrimal gland, comprising about 50% of all the tumors. Although malignant
transformation is not frequent, intraoperative tumor spill or inadequate
resection may be associated with an increase in the recurrence rate of
pleomor...

Primary central nervous system lymphomas are rare tumors that account for less
than 2% of primary intracerebral neoplasms. A 70-year-old male who had been
operated for prostatic adenocarcinoma ten months ago was admitted with the
complaint of amnesia, confusion, stupor and difficulty in walking. ...

Acute subdural hematoma (ASDH) is a neurosurgical emergency. Spontaneous
resolution of acute subdural hematoma is extremely rare and the mechanisms
are still unclear. However, several mechanisms of spontaneous resolution of
acute subdural hematoma have been reported. We have witnessed a patient

Several congenital anomalies of the odontoid process have been described in the
literature. Malformations of the dens include aplasia, hypoplasia, duplication,
condylicus tertius, os terminale (os avis) and os odontoideum. Os odontoideum
is the most common anomaly of the odontoid. However, there ...
The presentation, diagnosis, and treatment are described for a patient with an
ependymoma involving the left cerebellopontine angle (PCA). A 34-year-old
woman had left facial paralysis, hearing loss and headache in 8 months.
Computerized tomography (CT) revealed a mass lesion of the left PCA whic...
