An intracranial aneurysm with a diameter larger than 25 mm is considered a giant aneurysm (GA), and represent about 3-5% of all aneurysms. They are divided into two forms, specifically saccular and fusiform. Fusiform aneurysms are rare, making up only 1% of all intracranial aneurysms. They frequently involve the internal carotid artery (ICA) or the basilar(More)
The incidence of protozoal and helminthic infestations of the central nervous system (CNS) is less than 1%, but these infestations tend to follow a fatal course. They are more common among children, the elderly and immunocompromised individuals. CNS infections due to Entamoeba histolytica have been known for a long time. In recent years, especially in(More)
Neurofibromatosis type-1 (NF1) is a type of phakomatosis inherited in an autosomal dominant fashion. Also called 'von Recklinghausen disease' or 'peripheral neurofibromatosis', it comprises 90% of all neurofibromatosis (NF) cases. It is characterized by multiple peripheral nerve sheath tumors of benign character called neurofibromas. Surgical intervention(More)
Chiari Type-1 malformation is displacement of the cerebellar tonsils through the foramen magnum into the cervical spine and usually does not exceed the level of C2. It is 50-70% associated with syringomyelia. Nervous system involvement due to brucellosis is called neurobrucellosis, and neurological involvement rate has been reported an average of 3-5%,(More)
BACKGROUND Anaplastic astrocytoma (AA; WHO grade-III) patients determination of prognostic factors helps generating multimodal therapy protocols. For this purpose, in the Baskent University, Adana Medical Research Center, specific characteristics of AA patients who have surgery were retrospectively investigated and factors which affect prognosis has been(More)
Myelopathy is a rare but serious complication of radiation therapy (RT). Radiation myelopathy is white matter damage to the spinal cord developed after a certain period of application of ionizing radiation. Factors such as radiation dose and time between applications affect the occurrence as well as the severity of myelopathy. In those patients, positron(More)
We report a supratentorial primitive neuroectodermal tumor (sPNET) in 17-year-old primipara in the second trimester her pregnancy. Magnetic resonance imaging revealed a left frontoparietal mass with solid and cystic component. Gross-total resection was achieved via a left frontoparietal craniotomy. It was decided to suspend the radiotherapy and chemotherapy(More)
Infectious aneurysms constitute 4% of all intracranial aneurysms. The microorganisms responsible are most commonly streptococcus viridans, staphylococcus aureus and combined bacterial infections. Nonetheless, cases with no reproduction in their cultures are rather frequent. A 6-year-old patient admitted with complaints of sudden headache, nausea, vomiting(More)
