Background/aim:
The differentiation between cerebral metastases (CM) and high-grade gliomas (HGG) can be difficult on magnetic resonance imaging (MRI). The aim of this study was to evaluate the usefulness of searching two MRI signs (signal alteration in the adjacent cortex, SAAC, and peripheral rim sign, PRS), in order to distinguish between these...
The aim of this paper is to illustrate the potential of magnetic resonance imaging (MRI) in diagnosis, differential diagnosis, treatment planning and evaluation of therapy effectiveness of pyogenic brain abscesses, through the use of morphological (or conventional) and functional (or advanced) sequences. Conventional MRI study is useful for the ide...
Lymphocytic vasculitis of the central nervous system is an uncommon subtype of primary angiitis of the central nervous system (PACNS) - a rare inflammatory disorder affecting parenchymal and leptomeningeal arteries and veins.
Establishing diagnosis on the basis of neuroimaging only is difficult, as it can mimic a brain tumor. Thus, histological dia...
Calcifying pseudoneoplasm is rarely encountered along the neuraxis, and only few cases have been reported to involve the spine. Its exact pathogenesis is unknown, and has been regarded as an unusual reactive process which must be differentiated from infection or malignancy. This rare entity carries a good prognosis after surgical resection. We repo...
Purpose:
The aim of our study was to compare the relative cerebral blood volume (CBV) values obtained by first-pass dynamic susceptibility-weighted contrast-enhanced (DSC) T2-weighted magnetic resonance (MR) and perfusion computed tomography (P-CT) imaging in high-grade gliomas (HGG) in the same patient population.
Materials and methods:
Sixteen...
The purpose of this case report is to increase the knowledge about magnetic resonance spectrum of pyogenic abscesses of the brain. A 74-year-old woman presented with a left frontal lobe cystic mass, developed in the site of post-traumatic contusions after surgical evacuation of a subdural hematoma. MR imaging showed an ipsilateral mass lesion with...
The aim was to assess the value of unenhanced fluid-attenuated inversion recovery T2-weighted sequences (FLAIR-T2) in the differential diagnosis between solitary high-grade gliomas (HGG) and cerebral metastases (CM) appearing as contrast-enhancing cortico-subcortical lesions of the brain. In 69 patients with a contrast-enhancing cortico-subcortical...
To increase the knowledge about diffuse traumatic brain injury (TBI) by reporting the magnetic resonance imaging (MRI) findings observed in a patient with reversible extensive restricted diffusion of the brain at diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps.
An 18-year-old patient was admitted after high-energy clo...
Facial nerve schwannoma is a rare primary neurogenic tumour that may originate anywhere along the VII(th) nerve course. The clinical presentation is highly dependent on the location of the lesion along the nerve course and this makes the pre-operative diagnosis difficult without radiologic examination. The most common presentation is facial palsy a...
The purpose of this case report is to increase awareness of the spectrum of cerebral cavernous malformations (CCMs). We report the MRI findings and histological features of an uncommon case of a single giant (maximum diameter: >6 cm) cystic CCM of the left lateral ventricle occurring in a 26-year-old man who had undergone 30 Gy cranial irradiation...
This study was undertaken to evaluate the usefulness of perfusion-weighted imaging (PWI) in the differential diagnosis of ring-enhancing cerebral lesions, including abscesses, high-grade gliomas and metastases.
Nine cerebral abscesses (five pyogenic, four from Toxoplasma gondii), ten glioblastomas and five cerebral metastases in 19 patients were st...
Magnetic resonance brain scan in a 54-year-old man with ingravescent headache disclosed an expansive intraventricular non infiltrating process, hypointense in T1 and hyperintense in T2, without signal intensification after the injection of a paramagnetic contrast agent. The lesion was studied with diffusion and perfusion sequences. The Apparent Dif...
