Focal cortical dysplasia (FCD) is a developmental brain disorder characterized by localized abnormalities of cortical layering and neuronal morphology. It is associated with pharmacologically intractable forms of epilepsy in both children and adults. The mechanisms that underlie FCD-associated seizures and lead to the progression of the disease are unclear.(More)
BACKGROUND Subependymal giant cell astrocytoma is a brain tumor associated with tuberous sclerosis complex. There are two treatment options for subependymal giant cell astrocytomas: surgery or mammalian target of rapamycin inhibitor. The analysis of outcome of subependymal giant cell astrocytoma surgery may help characterize the patients who may benefit(More)
PURPOSE The aim of this study is to assess cognitive, emotional and social functioning in children and adolescents after the removal of craniopharyngioma. METHODS Twenty-seven children operated for craniopharyngioma and their parents participated in the study. Cognitive functions were assessed with WISC-R/WAIS-R-PL and Rey-Osterrieth Complex Figure Test.(More)
BACKGROUND AND PURPOSE Tethered cord syndrome (TCS) consists of solid adhesion of the distal spinal cord to adjacent structures, resulting in repetitive spinal cord traction during truncal movements. The condition is usually a sequel of lumbosacral dysraphism, spinal cord injury or surgical procedure. Clinical signs of TCS include sphincter disturbances,(More)
BACKGROUND AND PURPOSE The aim of the study was to evaluate registration accuracy in an electromagnetic navigation system applied to image-guided intracranial procedures in children. MATERIAL AND METHODS In a group of 34 children aged from 2 weeks to 17 years, 38 procedures were performed using electromagnetic navigation, including 24 neuroendoscopic(More)
PURPOSE Increasing incidence of pediatric brain tumors and improving survival rates encouraged us to assess long-term functional outcome of patients with cerebellar juvenile pilocytic astrocytoma (JPA). MATERIALS AND METHODS Our study encompassed 105 children treated since 1980-2005 and consisted in analysis of mailed, custom-designed questionnaires. (More)
Recent studies revealed the biological heterogeneity of medulloblastoma, with the existence of at least four groups which are associated with several clinical and morphological features. We investigated for further correlations between molecular types, location of tumours, their contrast enhancement pattern and survival of patients. Altogether 76 tumours(More)
Benign tectal tumours in children constitute a distinct group of brainstem gliomas, characterised by a usually benign clinical course. The aim of this paper was a retrospective analysis of 1) results of conservative treatment, 2) diagnostic value of CT and MRI and 3) correlation of the MR image with the clinical course of the disease. Our material includes(More)
INTRODUCTION Central nervous system tumors diagnosed before the end of the first year of life differ from those found in older children and in adults. The differences include mode of clinical presentation, anatomical distribution, histopathological diagnoses, response to therapy, and outcome. MATERIALS AND METHODS The material consists of 56 children (23(More)
Shot wounds become a growing clinical concern in the civilian setting, due to increasing popularity of air guns among minors. We present a pediatric case of a shot wound to the orbit with sparing of the eyeball and retention of airgun pellet in the retrobulbar space. The pellet was removed 3 months after injury via lateral orbitotomy. Pathophysiology and(More)
