BACKGROUND AND PURPOSE One former study reported higher prefrontal N-acetylaspartate (NAA) levels in patients with Asperger syndrome (AS). The objective of the current study was to test the hypothesis that patients with AS would have higher dorsolateral prefrontal and anterior cingulate cortex NAA/creatine (Cr) and that NAA/Cr would be correlated with(More)
BACKGROUND AND PURPOSE Subarachnoid hemorrhage (SAH) constitutes an important neurologic emergency. Some authors have suggested that fluid-attenuated inversion recovery (FLAIR) MR imaging can detect SAH that may not be apparent on CT scans but may be revealed by lumbar puncture. We sought to determine how often FLAIR MR imaging findings are positive for SAH(More)
BACKGROUND Aneurysmal bone cysts (ABCs) are uncommon lesions of the temporal bone and their occurrence in the calvarium is rare. CASE DESCRIPTION A case of a right temporal ABC is reported in a 14-year-old boy who presented swelling of the right temporal region. Magnetic resonance imaging showed a destructive and expansile bone lesion on the right(More)
BACKGROUND Medical therapy for hydatid disease of the brain has been reported with encouraging results especially in small or medium-sized cysts. To date, no other case correlating the metabolite levels of the cyst with albendazole treatment has been reported. CASE DESCRIPTION A 52-year-old woman presented with left hemiparesis and seizure. Cranial(More)
BACKGROUND The aim of this study was to perform a detailed anatomical analysis of petroclival venous structures as well as their patencies with 3D contrast-enhanced (CE) magnetic resonance venography (MRV) and to identify the potential contribution of these data to the therapeutic approach. METHODS Ten patients (8 women and 2 men) with unilateral(More)
Inferior vena cava (IVC) agenesis is a rare anomaly that is usually an incidental finding in radiologic work-up or it can rarely be symptomatic due to deep venous thrombosis of iliac veins. In this report, we present a case of IVC agenesis detected on lumbar spinal MR imaging scans by extensive epidural-paravertebral collateral vessels compressing the(More)
We report on the diffusion magnetic resonance imaging (MRI) and proton MR spectroscopy findings of a 26-year-old female patient with Sturge-Weber syndrome. Echo-planar trace diffusion MRI revealed mildly high signal intensity changes at parieto-occipital lobes on b = 1000 s/mm2 images, suggesting restricted diffusion. On corresponding apparent diffusion(More)
OBJECTIVES It has been shown that autistic spectrum patients have impaired theory of mind (ToM) performance; however, no study has investigated the relationship between ToM performance and brain neurochemistry in these patients. The present study aimed to investigate the correlations between dorsolateral prefrontal cortex (DLPFC) and anterior cingulate(More)
The aim of this study was to determine the brain regions associated with suppressing the image of an object. We used functional magnetic resonance imaging (fMRI) during five mental tasks (imagining, suppressing, erasing, free thinking and resting) performed by the subjects. The analysis showed that the suppressing, erasing and imagining conditions all(More)
PURPOSE Cases with intractable epilepsy may present with multiple lesions in their brains. Ictal-EEG carries a great value in identification of the primary epileptogenic source. On the other hand, removal of low-grade tumors located around the eloquent cortex may be risky with conventional techniques. Functional-neuronavigation (f-NN) is the integration of(More)
