Meningioma is the second most common brain tumor. The extent of peritumoral brain edema (PTBE) is one of the important prognostic factors in patients with meningioma.A 55-year-old female patient suffering from a progressive severe headache and mild left hemiparesis was referred to the Department of Neurosurgery, Rasool Akram Hospital (Tehran, Iran). The preoperative imaging revealed a 2×2 cm so...

Glioblastoma is one of the most common and lethal primary neoplasms brain. Patient survival has not improved significantly over past three decades patient median just year. Tumor heterogeneity thought to be a major determinant therapeutic failure reason for poor overall survival. This work aims comprehensively define intra- inter-tumor by mapping genomic mutational landscape multiple areas IDH ...

congenital granular cell tumor (gct) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. the newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. this lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. we report a case of an adult t...

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...

Glioblastoma is one of the most common primary brain tumors (80% of patients) that has a poor prognosis due to malignancy. Glioblastoma has an annual incidence of 5.26 per 100 000 population or 17 000 new diagnoses per year and so as the population aging, the number of patients is expected to increase. There is a growing body of literature investigating the tumor microenvironmenta...

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...

introduction: behcet's disease is a chronic disease with multisystem involvement characterized clinically by oral and genital aphthae, cutaneous lesions and ophthalmologic, neurologic and gastrointestinal manifestation. nervous system involvement occurs in 5.3 – 30% of patients, mostly in brain stem and basal ganglia. the common manifestations are pyramidal signs, central nervous plegia, p...

This Brain tumors are the mechanisms to control normal cells randomly and uncontrolled multiplication of cells in which growth is an abnormal mass of tissue. A tumor growth takes place within the skull and interferes with normal brain activity. Therefore, the first step is very important in tumor detection. Various techniques have been developed to detect tumors in the brain. Most crucial task ...
