Glioblastoma occurs rarely in pediatric patients (0.6–7.9% of all glioblastomas). Symptom duration is about 3–5 months prior to diagnosis with a dismal prognosis (median survival of 50 weeks). The authors describe two pediatric age patients with histopathologically confirmed glioblastoma multiforme whose lesions appeared within just 1 week of normal computed tomography scan and magnetic resonance imaging. Both patients had long-term survival (one of them 6 years and the other 3 years and 7 months) following tumor resection. The present report serially illustrates the very rapid development of glioblastoma in childhood and emphasizes the importance of serial neuroimaging as well as paying attention to sudden onset headaches in pediatric patients with inconclusive imaging findings.  相似文献

A 58-year-old woman presented with acute onset of global aphasia. Imaging studies revealed a left frontotemporal enhancing tumor and ischemic stroke in the territory of the middle cerebral artery. The patient was operated on, and the diagnosis of glioblastoma multiforme was confirmed. At the time of surgery, several branches of the left middle cerebral artery were found embedded in the tumor. One branch, which was infiltrated by tumor and completely occluded, was resected to achieve complete resection. Postoperatively, the stroke area within the middle cerebral artery territory increased, together with worsening of the patient's clinical status, thus requiring urgent decompressive craniectomy. Thereafter, the patient gradually improved, and received radiation therapy and chemotherapy with no recurrence after 24 months of follow-up. To our knowledge, glioblastomas presenting with ischemic stroke are rare, and such patients should be considered to be at high surgical risk.  相似文献

Purpose

Cerebellar glioblastomas in children are rare. As a result, an optimal treatment strategy has not yet been identified. A review of the characteristics of the disease as well as the effectiveness of various therapeutic modalities would help in optimizing the treatment paradigm.

Methods

We performed a detailed clinical, radiographic, and pathologic retrospective review of five patients (three boys and two girls, average age at presentation 7.2 years (range, 3–14 years)) and surveyed the literature for an additional 55 cases.

Results

Computed tomography and magnetic resonance imaging usually revealed a large lesion with minimal edema, heterogeneous contrast enhancement, and a discrete border. Subtotal tumor resection was performed in two patients and gross total resection in three patients. Immunostaining of the tumor cells with antisera to glial fibrillary acidic protein and vimentin was variably positive. Adjuvant therapy included local radiation and chemotherapy in all followed patients. Tumor recurrence was seen in two patients. Patients were followed from 2 months to 3.5 years (mean, 12 months). Two patients were dead at last follow-up with a mean survival of 9.5 months.

Conclusions

The prognosis for pediatric patients with cerebellar glioblastomas is dismal, even when compared to adult counterparts or other malignant posterior fossa tumors in children. Cerebellar glioblastomas have a tendency to recur and disseminate despite treatment with surgery, chemotherapy, and radiation. The poor outcomes seen with this tumor suggest that the optimal treatment strategy has yet to be elucidated and much work needs to be done.  相似文献

An 11-year-old boy with acute lymphoblastic leukemia had received prophylactic cranial irradiation (1800 cGy /10 fractions) and intrathecal methotrexate. Five years later, he developed a glioblastoma multiforme in the right frontal region while the leukemia was in remission. It is possible that the glioma may have been induced by radiation and /or chemotherapy.  相似文献

The clinical histories, histologic features, and immunohistochemical staining patterns for glial fibrillary acidic protein, vimentin, p53, and epidermal growth factor receptor (EGFR) of three cases of congenital glioblastoma multiforme are given and previous case reports are reviewed. Of the three cases reported in this series, two have had long-term survivals of greater than 2 1/2 and 5 1/2 years after surgery and surgery followed by chemotherapy, respectively. Both of these cases also demonstrated p53 protein accumulation, a finding in pediatric glioblastoma multiforme associated with poor prognosis. The third case occurred in an infant who died at birth and demonstrated a well-circumscribed tumor that did not invade adjacent brain parenchyma. Considering these three cases, the biological behavior in congenital glioblastoma multiforme may not be unfavorable as portrayed in the literature or as seen in its adult counterpart.  相似文献

Glioblastoma (GB) classically presents with symptoms of raised intracranial pressure and gradual progressive neurological deficits. An acute presentation, with intracerebral haemorrhage (ICH) and rapid clinical deterioration, occurs infrequently. Contemporary imaging modalities do not reliably reflect underlying mass lesions in parenchymal brain haemorrhage at first presentation. We report a delayed diagnosis of GB in a 21-year-old patient presenting with spontaneous ICH and a negative initial neurovascular workup. A comprehensive literature review was performed to investigate the incidence of malignant aetiology for spontaneous ICH in young adults, and to underscore the importance of early utilisation of diagnostic magnetic resonance imaging (MRI) in such cases.  相似文献

Meningioangiomatosis (MA) is a rare benign intracraneal lesion. The majority of cases are sporadic although the association of this lesion with familial neurofibromatosis (NF) type 2 is well known. NF-associated MA may be multifocal and is often asymptomatic and diagnosed at autopsy. Non-associated cases are usually symptomatic, occurs in children and young adults and frequently arise in leptomeninges and underlying cerebral cortex. In the present work, we describe two new non-associated cases of MA in two boys, seven and one year old with seizures that disappeared after surgical excision. Histopathologically, the lesion was predominantly cellular in one case and more fibrous in the other. From the literature review we concluded that sporadic cases present as single lesions which manifest by seizures or persistent headaches. Rarely MA has been described to coexist with meningiomas. Histopathologically, MA is characterized by a plaque-like proliferation of meningothelial and fibroblast- like cells surrounding small vessels and trapping islands of gliotic cortical tissue. The lesion does not show significant atypia, mitosis or necrosis. Although all cases of MA share unifying features, there are different degrees of histological presentation with cases predominantly cellular and others more fibrous and calcified. This could correspond to different stages in the evolution of the MA. Symptoms disappear with the complete excision of the lesion.  相似文献

Data on psychogenic movement disorders (PMD) in children are scarce, with most existing literature relating to adults only. We report 15 cases with the aim of highlighting the clinical characteristics, risk factors, comorbidity, treatment, outcome, and prognosis of PMD in children. Only 13% of cases had onset before age 10, with the mean age at onset being 12.3 years. Females were predominantly affected (F:M = 4:1). The most common types of movement disorders seen were dystonia (47%), tremor (40%), and gait disorders (13%). Multiple hyperkinetic phenomenologies were observed in many cases. Abrupt onset and precipitation by minor injuries, and stressful life events were commonly reported. Clinical clues on examination suggesting a psychogenic origin were similar to those identified in adults. A distinct feature of PMD in children was the predominant involvement of the dominant limb. The underlying psychiatric diagnosis was conversion disorder in the majority of cases. Time from symptom onset until diagnosis of a PMD varied broadly (between 2 weeks and 5 years). Treatment with cognitive and behavioral therapy and rehabilitation by a multidisciplinary team led to improvement in most cases. However, treatment was much more effective in children with a short time from symptom onset to diagnosis and treatment. © 2008 Movement Disorder Society  相似文献

We describe a case of a 64-year-old female who presented with concurrent left parietal glioblastoma multiforme and left occipital parasagittal meningioma. Both lesions were excised during the operation. There was no clinical evidence of phacomatosis. Aetiological and clinical aspects of the phenomenon are discussed.  相似文献

Glioblastoma multiforme (GBM) is a highly malignant glial tumor seen commonly in the cerebral hemispheres, but rarely encountered in the cerebellum. It may occur at any age, but is seen more often in adult age groups. Despite its rarity, GBM should be considered in patients with a ring-enhancing lesion in the cerebellum. No consensus regarding the best management has yet been established. However, multimodal treatment is currently available to deal with these lesions: wide excision with radiochemotherapy may improve and prolong the patients life. Although the outcome remains dismal, we emphasize that timely multi modal treatment may provide the patient a better outcome and longer life. Herein, we report 2 new cases of cerebellar GBM and discuss their outcome and present a review of the relevant literature.  相似文献

Muir-Torre syndrome (MTS) is an autosomal dominant subtype of nonpolyposis colorectal carcinoma (HNPCC) characterized by the development of sebaceous gland tumors and visceral malignancies. The most common subtype of MTS is characterized by germline mutations in mismatch repair (MMR) genes leading to microsatellite instability (MSI). Central nervous system tumors have only rarely been associated with MTS. In this report, we describe the development of a glioblastoma multiforme (GBM) in a patient with MTS. Immunohistochemical analysis of the patient's colon carcinoma and his GBM both revealed loss of the mismatch repair proteins mutS homolog 2 (MSH2) and mutS homolog 6 (MSH6).  相似文献

Sellar and suprasellar tuberculomas are rare. Patients with these lesions usually experience headache, vomiting, and hypofunction of pituitary gland; imaging reveals an enhancing sellar-suprasellar mass. We report 2 rare cases of sellar-suprasellar tuberculomas in children aged 8 and 6 years. One child presented with features of headache and vomiting, and the other presented with posterior pituitary dysfunction. In both cases, imaging revealed sellar-suprasellar masses. Both cases were multidrug-resistant tuberculomas. We discuss sellar-suprasellar tuberculomas, a rare form of neurotuberculosis in the background of an overall increase in multidrug-resistant tuberculosis, especially in children.  相似文献
