We report a case of a 45-year-old male patient with intraventricular cystic meningioma located in the left lateral ventricle. He presented with complaints of global headache, progressively increasing loss of memory, and frequent episodes of abnormal behavior, of 1 month duration. At the time of hospital admission, his general and neurological examination was normal. Neuroimaging studies showed ...

Undifferentiated pleomorphic sarcoma is a histologic diagnosis based on cell morphology. These tumors are found throughout the body. They are rarely found in the central nervous system and almost never occur as a primary intraventricular tumor. We present the unusual case of a 68-year-old woman with an intraventricular undifferentiated pleomorphic sarcoma. We go on to discuss the clinical prese...

Intraventricular tuberculoma (IVT) is extremely rare, CT and MRI patterns have been only sparsely described.  Herein, a case of intraventricular tuberculoma in a 40 year-old woman is reported.  At admission, the patient displayed malaise and was confused and deteriorated suddenly.  Brain CT and MRI findings were very similar to intraventricular meningioma.  The patient underwent surgery and tub...

abstract background: high resolution ct scan has made early diagnosis of intraventricular hemorrhage (ivh) easier. posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the ct scan. methods: 904 patients were admitted in the nsicu from march 2001 to march 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (gcs les...

BACKGROUND Gliosarcoma (GS) is a rare high-grade malignant tumor with poor prognosis. The survival period of GS ranges from 4 to 18.5 months. Rarely would it be over 40 months. Survival of intraventricular GS is less than 8 months. METHODS There were 2 cases of primary gliosarcoma in our hospital with long-term survival after resection, with one of pure intraventricular origin. We confirmed t...

Dissemination of tumor to the leptomeninges and cerebrospinal fluid represents a common pattern of metastasis for many cancers; however, few chemotherapeutic agents are available for intrathecal (i.t.) use and treatment results are often poor. We studied the neurotoxicity and pharmacokinetics of i.t. 4-hydroperoxycyclophosphamide (4-HC) in the rabbit and the activity of i.t. 4-HC in a VX2 rabbi...

The present essay is illustrated with magnetic resonance images obtained at the authors' institution over the past 15 years and discusses the main imaging findings of intraventricular tumor-like lesions (ependymoma, pilocytic astrocytoma, central neurocytoma, ganglioglioma, choroid plexus papilloma, primitive neuroectodermal tumors, meningioma, epidermoid tumor). Such lesions represent a subgro...

Intraventricular oligodendrogliomas are a rare subset of oligodendrogliomas. Analysis of the clinical and CT characteristics of 11 cases in the literature and eight new examples revealed specific radiographic features, which included the presence of an anterior, midline mass within the lateral ventricles composed of clumped calcifications within a dense, enhancing matrix. Hydrocephalus is a con...
