medulloblastoma/vomiting

A 10-year-old boy with newly diagnosed metastatic medulloblastoma was placed on high dose dexamethasone and ranitidine prior to surgery. The child underwent subtotal resection and was discharged 5 days postoperatively with an uneventful hospital course on a tapering dose of dexamethasone and

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

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

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

OBJECTIVE This study was undertaken to determine the effect of adjuvant chemotherapy combined with reduced-dose craniospinal irradiation (CSI) on survival and neurocognitive sequelae of radiotherapy (RT) in patients with average- risk medulloblastoma above the age of 3 years. METHODS Thirty-three

BACKGROUND The aim of this study was to identify the nature and severity of nutritional problems associated with the current treatment of medulloblastoma and to identify any risk factors for nutritional morbidity during treatment. METHODS A multicentre retrospective audit of medical and dietetic

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

Medulloblastoma is the most common posterior fossa tumor of childhood typically within the fourth ventricle. However, extra-axial medulloblastoma in posterior fossa is an uncommon diagnosis. We report a case in a 33-month-old male who presented with repeated complaints of abdominal pain,

In this study, the records of 17 adult patients with medulloblastoma treated with craniospinal radiation and 1 of 2 multiagent chemotherapy protocols were reviewed for progression-free survival, overall survival, and toxicity, and the patients were compared with each other and with similarly treated

BACKGROUND Adult medulloblastoma is a rare disease for which there is no internationally accepted standard of care. Treatment regimens have typically been modeled after pediatric protocols. We sought to review the presentation, management, and outcome of patients with adult medulloblastoma treated

Malignant gastrointestinal neuroectodermal tumor (GNET), is a rare soft tissue sarcoma. Here we report a case of GNET arising in the intestine of a 33-year-old female, who had been treated for gastric adenocarcinoma with surgery and chemotherapy at the age of 19, in 2001. Since then, she underwent

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

Gabapentin is well known for its pain control and antiepileptic effect, but its antiemetic effect is poorly investigated. Here we report on effective gabapentin use for refractory vomiting after craniotomy in two children with medulloblastoma in the fourth ventricle. The two pediatric patients (an

OBJECTIVE Starting in 1992, we began using a stereotactic radiosurgical (SRS) boost for the treatment of medulloblastomas. Four patients ranging in age from 7 to 42 years old have since been treated and are the subject of this retrospective study. METHODS All patients were initially treated with a

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
