gliosarcoma/癲癇性発作

Gliosarcoma is a rare brain tumor consisting of both glial and mesenchymal components. Metastatic gliosarcoma is rare; however, here we report a 31-year-old Chinese woman with cranial gliosarcoma metastatic to the liver, lymph nodes and the spinal cord. Initially, the patient presented with

Gliosarcoma is an uncommon malignant brain tumor composed of distinct sarcomatous and malignant glial cell elements. These tumors are defined as a variant of glioblastoma, and it can be developed by progression of the malignant glial cell tumors or primary tumors. We report a rare case with

Gliosarcoma is an unusual subtype of glioblastoma multiforme. Its characteristic features are biphasic configuration, constituting a definite, separate glial and sarcomatous differentiation, on histological evaluation. Herein, we present a rare case of Gliosarcoma that had presented only once in our

The authors present the case of a primary gliosarcoma with an isocitrate dehydrogenase-1 (IDH1) mutation. A 75-year-old man presented with a 3-day history of multiple focal seizures and was found on MRI to have a 2.2-cm left parietal enhancing mass lesion. Brain MRI for tremor performed 8 years

Gliosarcoma (GS) belongs to World Health Organization grade IV neoplasm and displaying glial and mesenchymal differentiation. Only rare cases of GS have been reported in the brachium pontis and 4th ventricle region. Here, we report a rare case of GS located on brachium pontis region and extending

A 63-year-old man complained of intermittent motor weakness of his arm. The magnetic resonance image (MRI) of his brain displayed a high signal lesion in right cingulate gyrus on T2 weighted image. One year later, he showed a stuporous mental status with repeated seizures, and the follow-up brain

A patient with a remote infarct, seizures, mild hemiparesis, and dysphasia became obtunded over four months and died. Computerized tomography (CT) over 5 years showed a consistent, large, wedge-shaped left hemisphere hypodensity with a central calcification, but without signs of mass effect. This

OBJECTIVE Gliosarcomas are rare, extremely high-grade, bimorphous malignant tumors of the central nervous system. Intraventricular location is extremely rare, and only a few case reports exist in the literature. The aim of our study is to review clinical, radiologic, and pathologic features of this

Astrocytic tumors, particularly gliosarcoma, may contain epithelial features in the form of trabecular, adenoid, papillary arrangement, and squamous metaplasia. A case of gliosarcoma with unusual epithelial feature is described. The patient was a 60-year-old male with frequent seizures. The mass was

A 51-year-old right-handed woman initially presented with generalized tonic-clonic seizures. MRI showed abnormal signal hyperintensity of the right temporal lobe that was thought to be consistent with ischemic stroke. Three years later, she developed an intensely enhancing centrally necrotic tumor

Gliosarcoma is a rare central nervous system (CNS) neoplasm with biphasic glial and non-glial malignant components. Here we describe the radiologic and histopathologic features observed in five cases of primary gliosarcoma. The mean age at diagnosis in the studied patients was 54.2 years; these

Desmoplastic infantile gangliogliomas are massive cystic tumors, typically occurring in the cerebral hemispheres of infants. They are remarkable pathologically for a prominent desmoplasia and, in some cases, for a cellular mitotically active component that can be readily interpreted as a malignant

The early appearance of high grade glioma on magnetic resonance (MR) imaging was retrospectively reviewed in the clinical records and MR images of 52 patients with intracerebral glioma treated in Osaka General Medical Center between 1997 and 2006. Three patients had no abnormal findings, and four

Two cases of pleomorphic xanthoastrocytoma (P X A) of young subjects (Kepes et al., 1979) are reported. Case 1 arose in 15-year-old boy admitted to the hospital with the complaint of severe headaches associated with nausea and vomiting of 1 month's duration. Computed tomographic scans showed a large

Between December 1996 and September 1998, 13 patients with advanced recurrent malignant brain tumors (9 with glioblastoma multiforme, 1 with gliosarcoma, and 3 with anaplastic astrocytoma) were treated with a single intratumoral injection of 2 x 10(9), 2 x 10(10), 2 x 10(11), or 2 x 10(12) vector
