Cetuximab, a monoclonal antibody specific for epidermal growth factor receptor, is increasingly used off-label and in early-phase trials for pediatric malignancies. Here, we report a patient with metastatic medulloblastoma receiving therapy with cyclophosphamide, vinblastine, and cetuximab. During
BACKGROUND
Chemotherapy is currently investigated in young children with medulloblastoma with the objective to omit or even delay craniospinal irradiation.
METHODS
We report a case of very early meningeal progression of medulloblastoma during postoperative chemotherapy in a 2.5-year-old boy. At 2
We report a case of a suspected secondary central nervous system(CNS)primitive neuroectodermal tumor(PNET)that developed 25 years after radiation therapy for a medulloblastoma of the cerebellum. At 5 years of age, the patient underwent craniotomy and subsequent radiation therapy of the whole
Medulloblastoma (MB) is rare in adults and treatment guidelines are consequently not well-established. Few modern series have reported long-term follow-up and treatment sequelae. We examined long-term outcomes of adult MB patients at one institution. Records of 29 consecutive patients (18 male, 11
OBJECTIVE
In adults, supratentorial primitive neuroectodermal tumor (sPNET) is a very rare undifferentiated embryoblastic neoplasm. Prognosis is worse in comparison to infratentorial medulloblastoma. Older age appears to be prognostically favorable. At present, 5-year survival rates remain below 50%
A retrospective analysis of seizure incidence in 511 patients who underwent posterior possa operations via a suboccipital craniectomy with prophylactic anticonvulsant agents, was performed. Thirty patients (5.9%) experienced seizures within 2 weeks postoperatively. Their mean age was 15 years.
A review is reported of the seizure incidence in 726 patients who underwent 740 posterior fossa operations via a suboccipital craniectomy without prophylactic anticonvulsant agents. Thirteen patients (1.8%) experienced seizures within 2 weeks postoperatively. Five of these patients (0.7% of the
OBJECTIVE
Seizures are common during and after treatment for a primary brain tumor. Our objective was to describe the incidence and risk factors for seizures in long-term survivors of pediatric brain tumors.
METHODS
In a retrospective, longitudinal study, we reviewed all consecutive patients during
A 3-yr-old female spayed grizzly bear (Ursus arctos horribilis) was evaluated for seizure activity along with lethargy, inappetence, dull mentation, and aggressive behavior. Magnetic resonance (MR) examination of the brain revealed a contrast-enhanced right cerebellar mass with multifocal smaller
We report a case of primitive neuroectodermal tumor (PNET) arising 8 years after chemotherapy and radiotherapy for acute lymphoblastic leukemia. A 15-year-old boy with a history of acute lymphoblastic leukemia, at the age of 7, underwent chemotherapy and 14Gy of radiotherapy to the whole brain. He
Ewing sarcoma/peripheral primitive neuroectodermal tumor (ES/pPNET) is a malignant small, round cell tumor arising from bone and soft tissue in children and young adults. It can occur at osseous and extraosseous sites. Its usual locations are diaphysis of long bones followed by pelvis, ribs,
The authors retrospectively reviewed ten pediatric brain tumor patients with intractable seizures who underwent lesionectomy without intentional identification and resection of the epileptogenic region to assess the clinical features and seizure outcome after lesionectomy in such patients. Seizures
A miniature dachshund aged 9 years and 7 months with a history of polyuria/polydipsia and depression was referred. General physical and neurological examinations revealed no obvious abnormalities. MRI of the brain revealed a large space-occupying lesion in the left frontal lobe. This was surgically
A 25-year-old male presented with difficulty in walking, loss of vision, and seizures. A clinical possibility of craniospinal meningeal pathology was considered. On computed tomography (CT) scan and magnetic resonance imaging, there was an enhancement of leptomeninges with few ring-enhancing lesions
