intracranial hemangiopericytomas (hpc) are rare vascular tumors. they account for 0.4% of primary central nervous system tumors. hpc is more commonly located supratentorially and tends to occur in a younger age group, with average age at presentation of 38–42 years. the tumor was found throughout the entire cns, usually superficially and closely related to the meninges. moreover, they have a st...

Chondromas are benign tumors that may be found in many parts of the body. Among intracranial neoplasms, tumors of cartilaginous origin are rare. It has been shown that most of these tumors arise from the skull base. Their occurrence in other parts of the intracranial cavity is unusual. Chondroma of falx is a rare neoplasm. In this report we introduce a case of falcine chondroma arose from front...

choroid plexus papillomas are rare intracranial tumors, accounting for less than 1% of all intracranial tumors in adults. however, they are relatively more common in children and constitute 1.5 to 4% of childhood intracranial tumors. in children, choroid plexus papillomas are predominately located in the lateral ventricles, followed by the forth and third ventricles and, rarely, in the cerebell...

Introduction: Schawannomas (neuromas, neurilemmomas) are benign tumors originating from showann cells or nerve fiber sheet cells. They are solitary, encapsulated tumors usually attached to, or surrounded by a nerve. Case Report: We present a case of left hypoglossal nerve schwannoma in a 19 year old man who was admitted with progressive left tongue atrophy. Conclusion: Schwannoma of the hy...

intracranial lipomas are congenital malformations. these uncommon lesions have an incidence of 0.1 to 1.7% of all intracranial tumors. most cases are located at midline and 5% are along the sylvian fissures. if symptomatic, seizures are the most common symptom. these tumors are slow growing and have favorable outcome. we report a case of a 25-year-old man whose ct and mri revealed a lesion in r...

Non-epithelial, benign extracranial neurogenic tumors of the nasal cavities are reported in the literature with extreme rarity. These tumors differ from the more common congenital gliomas, encephaloceles, etc. in that they sometimes are detached from the brain tissues. These tumors have intracranial origins. They are congenital or acquired and may involve any of the nerves inside the nose....
