The radiological diagnosis of cervical spondylotic myelopathy (CSM) has to be made as soon as possible, since surgery performed in earlier stages during the course of CSM was reported to be more successful when compared with later stages. We hypothesized that diffusion tensor imaging (DTI) may detect CSM in earlier stages, before the appearance of signal(More)
BACKGROUND AND PURPOSE Thromboembolic events may occur during or after the treatment of intracranial aneurysms with Guglielmi detachable coils (GDCs). The purpose of this study was to determine the frequency of thromboembolic events associated with balloon-assisted coil placement and to investigate possible risk factors for these events during(More)
BACKGROUND AND PURPOSE Comprehensive diagnostic criteria encompassing the varied clinical and radiographic manifestations of spontaneous intracranial hypotension are not available. Therefore, we propose a new set of diagnostic criteria. MATERIALS AND METHODS The diagnostic criteria are based on results of brain and spine imaging, clinical manifestations,(More)
PURPOSE Our aim was to investigate the [(1)H] MR spectroscopy (MRS) findings of Lafora Disease (LD), which is a disabling form of progressive myoclonic epilepsy. METHODS Twelve patients diagnosed with LD and 12 control subjects underwent MRS studies with single-voxels of 8 cc obtained in the frontal lobe, pons, and cerebellum. The metabolites and NAA/Cr,(More)
AIM To report our experience with computed tomography (CT)-guided percutaneous catheter drainage (PCD) of iliopsoas abscesses. MATERIALS AND METHODS Twenty-two iliopsoas abscesses in 21 patients (11 women, 10 men) aged between 18 and 66 years (mean 36 years) were treated with PCD. Abdominal CT demonstrated the iliopsoas abscesses, which were definitively(More)
Reports on citrullinemia usually describe the imaging findings in the adult form of the disease. However, neuroimaging findings of neonatal cases are seldom reported. We report on the diffusion-weighted magnetic resonance imaging (MRI) findings of a one-year old infant with neonatal citrullinemia during an acute episode and discuss possible underlying(More)
Cerebral venous thrombosis presenting with subarachnoid hemorrhage (SAH) is very rare. We report a case of cerebral venous sinus thrombosis as an initial manifestation of SAH. A 14-year-old boy was admitted with progressive headache, nausea, vomiting, diplopia, and gait disturbance. Cerebral computed tomography scan showed a widely SAH in the basal(More)
We present a case of wide-necked giant aneurysm located at the P1-P2 segment of the posterior cerebral artery. The initial goal for treatment of the aneurysm was hemodynamic flow redirection with subsequent thrombosis so the procedure and involved stent placement to the neck of the aneurysm without any filling material. During follow up, significant(More)
BACKGROUND Routine lumbar spine magnetic resonance imaging (MRI) may not show any evidence of the cause of sciatica in some cases. The relationship between nerve root compression detected on lumbar MRI and sciatica is also sometimes uncertain. PURPOSE To ascertain whether axial (and, when necessary, sagittal and coronal) short-tau inversion recovery or(More)
PURPOSE To demonstrate the feasibility and preliminary efficacy of endovascular embolization of peripheral congenital vascular malformations (VMs) with use of a nonadhesive liquid embolic agent, Onyx. MATERIALS AND METHODS Nine patients with a mean age of 20.8 years had local low-flow (n = 4), local high-flow (n = 3), or diffuse high-flow (n = 2) VMs(More)
