Fluid collectionsSubarachnoid hemorrhageTraumatic brain injuryExtra-axial fluid collections (EAC) frequently develop following decompressive craniectomy (DC). Management of EAC remains poorly understood, and there is a dearth of information on how to predict their clinical course. Thus, we aim to better...
Brain tumors can be intra-axial or extra-axial. The intra-axial tumors are located within brain parenchyma and arise from the brain cells, while the extra-axial tumors are located outside brain parenchyma and arise from structures lining the brain or surrounding it. The intraventricular tumors ar...
Auditory symptoms of brain stem disorder depend on the nature of the lesion. This study compared auditory test results in 28 patients with extra-axial, 11 patients with intra-axial, and 6 patients with combined extra-axial and intra-axial brain stem disorders. Patients with extra-axial lesions ...
A case of Erdheim-Chester disease demonstrates cerebral hemispheric involvement, as well as and intraaxial and extraaxial brain stem involvement in a patient with symptoms of paraparesis, urinary incontinence, visual loss, ataxia, vertigo, proptosis, and nystagmus. Persistent gadopentetate dimeglumine enha...
Extra-axialHead and neckCytotoxic oedemaHypercellularityDiffusion-weighted imaging (DWI) has a central role in the assessment of the brain parenchyma, particularly in the context of acute stroke. However, the applications of DWI extend far beyond the brain parenchyma and include the assessment of ...

Extraaxial tumors of the nervous system are extra-cerebral and often benign. Meningiomas, schwannomas and metastasis are the part of this group. The onset of a tumor occurs from the accumulation of genetic and epigenetic alterations in cells. To understand the molecular mechanism of tumor ...
The quantification of cerebrospinal fluid (CSF) in the human brain has shown to play an important role in early postnatal brain developmental. Extra-axial fluid (EA-CSF). which is characterized by the CSF in the subarachnoid space, is promising in the early detection of children at risk ...
The presence of excessive extra-axial fluid detected as early as 6 months and the lack of resolution by 24 months is a hitherto unreported brain anomaly in infants who later develop autism spectrum disorder. This is also the first magnetic resonance imaging evidence of brain enlargement in autism...
Brain DiseasesHematoma, SubduralUltrasonographyInfantExtra-axial fluid collections were identified in six infants by transfontanelle cranial sonography. Confirmatory computer tomography (CT) scans were performed following the sonograms in five of these patients. These extra-axial fluid collections were varied ...
