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 Pituitary carcinomas are extremely rare tumors of the adenohypophysis. The presence of craniospinal and/or systemic extracranial metastases is the only reliable criterion for the diagnosis of pituitary carcinoma. To date, only 2 cases have been reported correctly by fine needle aspiration biopsy (FNAB). We present an additional case of pituitary(More)
We report a case in which an intrarenal arteriovenous fistula caused the nutcracker effect. Color Doppler sonography of the left renal artery showed a peak systolic velocity of 150 cm/second and renoaortic ratio of 2.1. The left renal vein was significantly dilated, and the adjacent renal artery was kinked. A stenosis in the left renal vein at the(More)
OBJECTIVE Our aims were to evaluate the detectability, configuration, location, and dimensions of the cisterna chyli on heavily T2-weighted images obtained with a single-shot fast spin-echo technique and to determine whether the disorders that have the potential to affect the abdominal lymphatic drainage could change the cisternal dimensions.

PURPOSE To investigate the diagnostic value of direct contrast-enhanced three dimensional magnetic resonance (3D MR) venography in mapping the deep venous system of the upper extremities and to plan potential interventional procedures. MATERIALS AND METHODS Nineteen cases with the diagnoses of end-stage renal disease with multiple hemodialysis catheter(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)
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)
Orbital wall infarction and subperiosteal haematomas are unusual manifestations of sickling disorders. Here we report an 11-year-old girl with sickle cell anaemia having multiple skull infarctions including the orbital bony structures associated with subperiosteal haematomas. The diagnosis was made by MRI, which showed bone marrow changes and associated(More)
The purpose of this study is to compare contrast-enhanced three-dimensional (3D) magnetic resonance (MR) portograms to Doppler sonography in detection of portal venous abnormalities. Thirty-five consecutive patients, who were suspected of having portal venous system abnormalities, were examined with MR portography and Doppler sonography. Vascular(More)
