Abstract Neuroimaging plays a pivotal role in the clinical practice of brain tumors aiding diagnosis, genotype prediction, preoperative planning, and prognostication. The most commonly seen adults are extra-axial lesions like meningioma, intra-axial gliomas pituitary gland. Clinical features may be localizing partial seizures, weakness, sensory disturbances or nonspecific headache. On suspicion...

non-epithelial, benign extracranial neurogenic tumors of the nasal cavities are reported in the literature with extreme rarity. these tumors differ from the more common congenital gliomas, encephaloceles, etc. in that they sometimes are detached from the brain tissues. these tumors have intracranial origins. they are congenital or acquired and may involve any of the nerves inside the nose. thes...

An accurate and early diagnosis of brain tumors based on medical imaging modalities is great interest because are a harmful threat to person’s health worldwide. Several techniques have been used analyze tumors, including computed tomography (CT) magnetic resonance (MRI). CT provides information about dense tissues, whereas MRI gives soft tissues. However, the fusion images has little effect enh...

Though most primary brain gliomas present as a single mass lesion in the brain, this potential diagnosis must be considered in the differential diagnosis when faced with a case of multifocal brain mass lesions. Among the most common brain tumors in humans, glioblastomas can be classified into four classes, one of which consists of anaplastic astrocytomas (AA). Due to its significant malignant p...

tumors of the central nervous system (cns), occur relatively frequently during the early years of life. they are the most common solid tumors of childhood and are second only to leukemia in overall cancer incidence and account for a high proportion of deaths. in different studied performed in several countries, astrocytomas and other gilomas (combined) account for half of the cns malignancies, ...

The study of neuroimaging is a very important tool in the diagnosis central nervous system tumors. This paper presents evaluation seven deep convolutional neural network (CNN) models for task brain tumor classification. A generic CNN model implemented and six pre-trained are studied. For this proposal, dataset utilized Msoud, which includes Fighshare, SARTAJ, Br35H datasets, containing 7023 MRI...

Cavernous hemangiomas (CHs) can be found in all intracranial structures, especially the brain parenchyma. Most spinal are of vertebral origin. Spinal cavernous that do not hold vertebrae called "pure" types. Pure epidural (SECHs) very rare and account for approximately 4% lesions. Here is a case pure thoracic SECH detected 42-year-old female patient with progressive paraparesis sensory loss bel...
