In the studies concerning the pathology of the auditory pathway in the vestibulocochlear system, few use advanced neuroimaging applications of magnetic resonance imaging (MRI) such as diffusion tensor imaging (DTI). Those who did use reported DTI changes only at the lateral lemniscus and inferior colliculus level. The aim of our study was to determine diffusion changes in the bilateral auditory pathways of subjects with unilateral acoustic neuroma (AN) and compare them with healthy controls.

The purpose of this article was to review the anatomy of the cavernous sinus (CS), illustrate numerous lesions that can affect the CS, and emphasize the imaging characteristics for each lesion to further refine the differential diagnoses. The CS, notwithstanding its small size, contains a complicated and crucial network that consists of the carotid artery, the venous plexus, and cranial nerves. The wide-ranging types of pathologies that can involve the CS can be roughly classified as tumoral, congenital, infectious/inflammatory/granulomatous, and vascular. Conditions that affect the CS usually lead to symptoms that are similar to each other; thus, for diagnosis, imaging procedures are required. Radiological evaluations are also required to detect pre- and postoperative CS invasion. Magnetic resonance imaging, which can be supplemented with thin-section contrast-enhanced sequences, is the preferred imaging technique for evaluating the CS. For correct diagnosis of CS lesions and accurate evaluations of CS invasions, it is essential to carefully analyze the anatomical structures within the CS and to acquire precise knowledge about the imaging features of CS lesions, which may frequently overlap.

Glutaric aciduria type-1 (GA-1) is a disorder of amino acid metabolism. The usual clinical-onset is an acute encephalopathic crisis in early childhood. There are only a few cases diagnosed in older age groups. MRI features of the disease are well defined. However, there are limited number of studies concerning advanced neuroimaging findings. We present DWI and MRS findings of an 11 year-old GA-1 patient admitted with an encephalopathic crisis. Diffusion restrictions in bilateral basal ganglia, corpus callosum and periventricular deep white matter were observed. In left occipital periventricular white matter and left basal ganglia, mild increased Cho/Cr and MI/Cr ratios and decreased NAA/Cr ratio were detected. Also inverted double lactate peak (TB: 135 ms) was present at 1.33 ppm in the left basal ganglia. In addition to these findings, a peak at 1.56 ppm above the baseline was seen on both short and long echo-time MRS in left occipital lobe deep white matter which may show accumulation of degradation products of amino acids in the GCDH enzyme deficiency.

Purpose We aimed to evaluate the change in bilateral auditory pathways using diffusion tensor imaging (DTI) after gamma knife radiosurgery (GKR) and to determine the relationship between the radiosurgical treatment variables and DTI findings.
