BACKGROUND: Glioma is the most common primary malignant brain tumor. Nuclear factor κB (NF-κB) has emerged as a regulator of phenotype in glioma, and particular glioblastoma multiforme, with clear relation to tumor size, recurrence, invasiveness. AIM: The aim study was analysis NF-κB expression gliomas different histologic types grades its correlation various clinicopathologic indicators. METHO...

ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. a seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. imaging findings were suggestive of left temporal high grade lesion. during surgery there was well ca...

OBJECTIVE Meningiomas are neoplasms that arise from the meninges of the central nervous system (CNS). They constitute about 25.6% of CNS tumors diagnosed in Egypt. Some morphological variants of meningiomas display aggressive behavior, leading to brain-invasive growth pattern. Although meningiomas are usually treated by complete surgical excision, the risk of postoperative recurrence remains. H...

INTRODUCTION: Magnetic resonance imaging plays an important role in the detection and evaluation of brain tumors. Conventional contrast-enhanced MRI delineates areas of blood brain barrier (BBB) leakage, but is less reliable in assessing tumor grade and distinguishing radiation-induced necrosis (RN) from tumor recurrence. The gold standard for distinguishing RN from tumor recurrence is F fluoro...

PURPOSE The prevalence of nonconvulsive status epilepticus (NCSE) in brain tumor patients is unknown. Since NCSE has been associated with significant mortality and morbidity, early identification is essential. This study describes the clinical and EEG characteristics, treatment, and outcome in brain tumor patients with NCSE. METHOD All patients admitted to Mount Sinai Hospital from 2009 to 20...

Automatic segmentation of brain tumors is an essential but challenging step for extracting quantitative imaging biomarkers accurate tumor detection, diagnosis, prognosis, treatment planning and assessment. Multimodal Brain Tumor Segmentation Challenge 2020 (BraTS 2020) provides a common platform comparing different automatic algorithms on multi-parametric Magnetic Resonance Imaging (mpMRI) in t...

the gastrointestinal stromal tumor (gist) is a rare mesenchymal tumor of gastrointestinal (gi) tract. this tumor has tendency to liver metastasis and peritoneal recurrence, however; the primarily lymph node involvement or metastasis is rare. here we reported a 17-years-old girl with multifocal gastric gist and multiple lymph node involvement at presentation and recurrence in celiac lymph nodes....

UNLABELLED We evaluated the diagnostic accuracy of PET with l-methyl-(11)C-methionine ((11)C-MET) for the differentiation of recurrent brain tumors from radiation necrosis. METHODS Seventy-seven patients who had been previously treated with radiotherapy after primary treatment for metastatic brain tumor (n=51) or glioma (n=26) were studied to clarify the diagnostic performance of (11)C-MET PE...

Artificial intelligence (AI) is rapidly integrating into diagnostic methods across many branches of medicine. Significant progress has been made in tumor assessment using AI algorithms, and research underway on how image manipulation can provide information with diagnostic, prognostic treatment impacts. Glioblastoma (GB) remains the most common primary malignant brain tumor, a median survival 1...

BACKGROUND Treatment strategies for brain metastasis from lung cancer have been making progress. The aim of this retrospective analysis was to investigate the post-recurrent prognostic factors in patients with brain metastasis after complete resection of non-small cell lung cancer (NSCLC). METHODS We retrospectively reviewed the medical records of 40 patients found to have postoperative brain...
