Article Synopsis
- The study aims to examine normal MRS features of the trigeminal nerve and compare metabolite concentrations in trigeminal neuralgia patients' affected and unaffected nerves.
- A total of 33 patients underwent MR studies, measuring various metabolites like NAA, Cr, and Cho, with significant differences found in metabolite concentrations on the affected side.
- Results indicated higher Cr concentrations in all parts of the affected nerves, with notable differences in NAA and myoinositol concentrations as well; vascular conflicts were present in a majority of patients, often correlating with neuralgia symptoms.
Posterior reversible encephalopathy syndrome (PRES) is an uncommon clinicoradiological syndrome that is characterized by acute neurological symptoms such as headache, convulsion, visual disturbance, and altered consciousness. The characteristic magnetic resonance (MR) finding is vasogenic edema, predominantly in the subcortical areas of the posterior parietal and occipital lobes on T2-weighted and fluid-attenuated inversion recovery (FLAIR) sequences. Herein, we described a rare case of PRES induced by cyclosporine (CsA) after an allogeneic hematopoietic stem cell transplantation (HSCT) from a sibling donor.

Material And Methods: One hundred and fifty randomly-selected patients referred to our department for MRI examination were included. Participants were asked to complete the Spielberger State and Trait Anxiety Inventory (STAI) to monitor subjective evaluation of anxiety.
Objective: The objective of the study was to examine a possible relationship between morphometric corpus callosum (CC) measurements, age, and gender characteristics using MR images.
Materials And Methods: The medical data and MR examinations of 436 consecutive subjects were retrospectively reviewed. The CC thickness from five different sites, and additionally splenium length, height, and total length of the CC, and the splenium index (SI) were measured with a mid-sagittal T1-weighted sequence.
Background: Nasopharyngeal carcinoma is a rarely seen tumor in childhood. It is mostly detected late as the clinical features are similar to other childhood tumors which affect the nasopharynx and adenoidal hypertrophy. Therefore, the radiological features of childhood tumors of the nasopharynx must be well known.
