introduction: meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. it can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. as a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. trauma and viruses are possible e...

Brain tumor is the most common and deadliest disease that can be found in all age groups. Generally, MRI modality adopted for identifying diagnosing tumors by radiologists. The correct identification of regions its type aid to diagnose with followup treatment plans. However, any radiologist analysing such scans a complex time-consuming task. Motivated deep learning based computer-aided-diagnosi...

The main goal of brain tumor surgery is to maximize tumor resection while preserving brain function. However, existing imaging and surgical techniques do not offer the molecular information needed to delineate tumor boundaries. We have developed a system to rapidly analyze and classify brain tumors based on lipid information acquired by desorption electrospray ionization mass spectrometry (DESI...

Dysembryoplastic neuroepithelial tumor (DNET) is a recently described, morphologically unique, and surgically curable low grade brain which included in the WHO CNS classification as neuronal mixed glial tumor. It usually seen children young adults. This entity first described by Damas-Duport 1998 non-recurring with an excellent prognosis. We present case of 30 year old female experiencing seizu...

results: the only significant difference was the older age of the malignant group vs. benign group (p = 0.001) regarding demographic findings. as concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (p = 0.001). additionally, data analysis of patients as a total group showed that specificity (96.4%), posit...

The 2021 World Health Organization (WHO) classification of brain tumors,[1] as a follow-up to the 2016 update, incorporates validated molecular markers previously established histomorphological features and has led significant shift in diagnosis management adult diffuse gliomas. provides distinction between astrocytoma Isocitrate Dehydrogenase (IDH) mutant grade 4 IDH-wildtype glioblastoma, whi...

Introduction: Hydrocephaly is a common complication of intra ventricular brain tumors. The aim of this study was to determine, demographic and clinical features and type of hydrocephaly before and after surgical interventions in patients with intra ventricular brain tumor surgery. Material and methods: In a cross-sectional study, 100 patients with intra ventricular brain tumors who were candid...

giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...

carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating in the enterochromaffin cells and secreting mainly serotonin. the diagnosis is based on clinical symptoms, hormone levels, radiological and nuclear imaging, and histological confirmation. the clinical symptoms are characterized by flushing, diarrhea, abdominal pain, telangiectasia and/or bronchoconstriction. however, mo...

Now a day’s brain tumor detection is an important matter in computer aided diagnosis for medical applications. The classification process and plays vital role to the tumors. existing method concentrates on detection, features extraction classification. Though traditional Algorithms suffered from less accuracy takes more time execution. To enhance premature stage classification, main intension o...
