[Supratentorial primitive neuroectodermal tumor: report of a surgical case].

Alleen geregistreerde gebruikers kunnen artikelen vertalen

We reported a rare case of supratentorial primitive neuroectodermal tumors (sPNET) and reviewed the literature. A 15-year-old girl presented with a one-month history of headache and vomiting. CT scans showed a huge, solid and cystic tumor with calcification, occupying the left anterior cranial

[Pediatric medulloblastoma presenting as cerebellar hemorrhage: a case report].

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Medulloblastomas usually cause cerebellar ataxia and acute hydrocephalus owing to their increase in size. Cerebellar hemorrhage is an extremely rare initial clinical presentation of medulloblastoma. Herein, we report a case of medulloblastoma in an 8-year-old girl who presented with initial

Intracranial metastasis from primary spinal primitive neuroectodermal tumor.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Primary spinal primitive neuroectodermal tumors (PNET) are rare tumors, with only 94 cases reported till date. Metastasis to brain from a spinal PNET is even rarer. In the present report, we evaluate the pathology and treatment of solitary intracranial metastasis from spinal PNET in a 22-year-old

Primary leptomeningeal primitive neuroectodermal tumor.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Leptomeningeal metastases are a common complication of medulloblastomas and other primitive neuroectodermal tumors (PNETs). Much rarer are PNETs apparently arising in the leptomeninges. An 8-year-old boy presented with headache and vomiting, due to neoplastic meningitis from primary neuroectodermal

[The leptomeningeal form of primary neuroectodermal tumor].

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Brain neoplasms as primary leptomeningeal forms are rare, particularly if the case in point is primary neuroectodermal tumors (PNET). In the literature, there are only few reports on this topic. The authors describe one of such rare cases. A 21-years-old man was admitted to a hospital for complaints

A novel case of a CAT to AAT transversion in codon 179 of the p53 gene in a supratentorial primitive neuroectodermal tumor harbored by a young girl. Case report and review of the literature.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND The most common cytogenetic abnormality encountered in primitive neuroectodermal tumors (PNET)/medulloblastoma is loss of heterozygosity in the region of the short arm of chromosome 17. There is some evidence that supratentorial PNET has different cytogenetic markers than infratentorial

Lipomatous medulloblastoma: a rare adult tumor variant with a uniquely favorable prognosis.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND Lipomatous medulloblastoma is a rare but apparently distinct variant of medulloblastoma. There have been only 14 prior published cases. We report an additional case of an adult who presented with a multicentric form of this unique lesion. METHODS A 45-year-old woman underwent magnetic

[Childhood medulloblastoma].

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Medulloblastoma is one of the most common malignant childhood brain tumors. It is a primitive neuroectodermal tumor (PNET) and predominantly arises in the cerebellum and 4th ventricle. Most cases of medulloblastoma are sporadic, but some predisposition syndromes are known, such as SUFU and Gorlin

Primary Ewing's sarcoma/peripheral primitive neuroectodermal tumor at the vertex of the skull with elevated serum carcinoembryonic antigen: case report.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

A primary Ewing's sarcoma arising in the skull is relatively rare. Although a small number of case reports noted elevated carcinoembryonic antigen (CEA) in patients with primary central nervous system (CNS) neoplasms, there is no report of Ewing's sarcoma/peripheral primitive neuroectodermal tumor

Concurrent IDH1 and SMARCB1 Mutations in Pediatric Medulloblastoma: A Case Report.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Isocitrate Dehydrogenase-1 (IDH1) is a driver gene in several cancers including brain tumors such as low-grade and high-grade gliomas. Mutations of SMARCB1 were described in atypical teratoid rhabdoid tumors and to date have not been associated with the pathogenesis of medulloblastoma. We report

A 15-Year-Old Girl With Sudden Onsent Reversible Neurologic Symptoms After Cranial Irradiation for Medulloblastoma.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

A 15-year-old girl with history of medulloblastoma was evaluated for headache and neurologic deficits 5 years after completion of initial radiation therapy and 3 years following completion of reirradiation. Neurologic examination was notable for new-onset left hemianopia, hemiparesis, and neglect.

Craniospinal Irradiation in Medulloblastoma using High Energy Medical Linear Accelerator: an Innovative Approach to Planning Technique.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Craniospinal irradiation (CSI) of medulloblastoma poses technological challenges due to the involvement of large treatment volume. Commonly, the whole treatment length is covered with two different isocentric plans in which the junction is shifted after every five fractions to overcome

Duration of symptoms prior to diagnosis is related inversely to presenting disease stage in children with medulloblastoma.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

BACKGROUND The authors tested the hypothesis that children with a longer duration of symptoms prior to diagnosis of medulloblastoma have more advanced disease. In addition, they evaluated whether there are correlations between gender, duration of presenting symptoms, and disease stage. METHODS The

"Primary" leptomeningeal medulloblastoma.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

We report the case of an 8-year-old boy who presented with a 2-month history of headaches and mild visual impairment and was found to have a medulloblastoma with primary leptomeningeal involvement. No mass lesion was found on imaging studies, during subsequent intraoperative surgical inspection or
