Intracranial dermoid cysts are rare tumors derived from ectopic epithelial cells. They are slow-growing benign entities, but can cause significant morbidity through compression of neurovascular structures and, rarely, rupture into the subarachnoid space. We present a rare case of a spontaneously ruptured intracranial dermoid cyst presenting as new onset seizures due to chemical meningitis cause...

tumors and the usual location for intracranial germinomas is the midline structures such as the pineal and suprasellar regions (1). To the best of our knowledge, intracranial germinoma primary arising in the lateral ventricle has not yet been reported in the medical literature. We describe here a case of lateral ventricular germinoma that showed rapid progression and it mimicked choroid plexitis.

Dr. Paulo Valdeci Worm – Rua Carlos Trein Filho 550 / 403 90450-120 Porto Alegre RS Brasil. E-mail: [email protected] Non-traumatic subdural haematomas are very rare especially those associated with intracranial meningiomas. Intracranial tumors hemorrhage occurs in 39% of all cases. They are a malignant pathology such as metastatic tumors or gliomas. They usually present with seizures hemip...

Many intracranial malign tumors including glioblastomas, malign astrocytomas. medulloblastomas. some of the pineal region tumors and ependymomas have a high potential for metastasis (3.4,11). These tumors usually spread via the cerebrospinal fluid pathways and locate on the surface of the spinal cord. Pure intramedullary location of a metastatic mass from medulloblastoma is a very rare patholog...

Tumors of the jugular foramen remain challenging lesions despite advances in surgical technique and medical technology. Tumors with extensive extra- and intracranial components necessitate both radical neck dissection maneuvers combined with skull base approaches. We present a single surgeon's perspective in managing these difficult tumors.

Glossopharyngeal schwannomas are rare tumors in spite of the fact that acoustic schwannomas account for 8%-10% of intracranial tumors. There have been 23 reported cases in the literature. This report of five cases is the largest series of these tumors. The presentation, radiological workup, operation, and long-term postoperative results will be presented, along with a review of the literature.

OBJECTIVE There is a rich literature confirming the default mode network found compatible with task-induced deactivation regions in normal subjects, but few investigations of alterations of the motor deactivation in patients with intracranial lesions. Therefore, we hypothesized that an intracranial lesion results in abnormal changes in a task-induced deactivation region compared with default mo...

A rare case of an intracranial haemangiopericytoma with extra-cranial extension in a 60-year-old female patients’ is presented. Intracranial haemangiopericytomas are uncommon, dural-based tumors. It is classified as a tumor of uncertain origin in the WHO system.Haemangiopericytomas arise from Pericytes of Zimmerman that surround capillaries and not archetypical meningothelial arachnoid cap cell...

The authors describe a rare case of increased intracranial hypertension consequent to a spinal cervical glioblastoma multiforme in a young patient. They analyse the physiopathology of intracranial hypertension in spinal tumors and the rarity of such kind of tumor in this location, and its clinico-pathological aspects.

Epidermoid cysts are common benign tumors comprising around 1% and 2% of all intracranial tumors. Their usual locations include the parasellar region cerebellopontine angle, less commonly, Sylvian fissure, suprasellar region, cerebral, cerebellar hemispheres. located in brain stem rare. These epidermoid similar to epidermoids arising skin which contain cheesy flaky-white soft pultaceous materia...
