Unilateral posterior cervical spinal cord infarction due to spontaneous vertebral artery dissection.

Context: Ischemia of the cervical spinal cord is a rare complication of spontaneous vertebral artery dissection (VAD) and usually involves the ventral portion. We describe a less evocative clinical presentation and images of unilateral posterior spinal cord infarction due to spontaneous VAD in order to facilitate early diagnosis.

Findings: A previously fit 30-year-old man presented with persistent headaches and proximal motor deficit of the right arm.

Upfront Bevacizumab and Temozolomide or Fotemustine before Radiotherapy for Patients with Glioblastoma and Severe Neurological Impairment at Diagnosis.

Unresectable glioblastomas with severe neurological impairment at diagnosis have a poor prognosis. The conventional approach using a temozolomide-based chemoradiotherapy has limited efficiency on patients in the RTOG RPA V-VI classes. The activity of the antiangiogenic monoclonal antibody bevacizumab is well defined in recurrent glioblastoma, despite the fact that its impact on survival is not yet established.

Nontraumatic subarachnoid hemorrhage management: evaluation with reduced iodine volume at CT angiography.

Purpose: To evaluate the technical quality and the diagnostic performance of a protocol with use of low volumes of contrast medium (25 mL) at 64-detector spiral computed tomography (CT) in the diagnosis and management of adult, nontraumatic subarachnoid hemorrhage (SAH).

Materials And Methods: This study was performed outside the United States and was approved by the institutional review board. Intracranial CT angiography was performed in 73 consecutive patients with nontraumatic SAH diagnosed at nonenhanced CT.

[Left mesiotemporal lesions and anterograde memory impairement: a case of neurosyphilis].

Introduction: Neurosyphilis has become uncommun in the developed countries.

Observation: We report a case of neurosyphilis with limbic presentation, left mesiotemporal lesions on MRI and severe anterograde amnesia.

Discussion: Pathogeneses of MRI findings are unknown.

[Imaging of cranial gunshot traumas].

Cranial traumas from gunshot wounds are characterised by the impact of a high velocity projectile. There are therefore serious, life threatening traumas. CT Scan is essential in the emergency setting for initial evaluation of traumatic bone and parenchymatous injuries to determine the indication for neurosurgery and appropriate medical management.

Posterior reversible encephalopathy syndrome: a case of unusual diffusion-weighted MR images.

Posterior reversible encephalopathy (PRES) represents an uncommon entity related to multiple pathologies, the most common of which is hypertensive crisis. PRES is classically characterized as symmetrical parieto-occipital edema, but may affect other areas of the brain. Diffusion-weighted magnetic resonance imaging (DWI) is important for differentiating between vasogenic and cytotoxic edema.

Giant cystic widening of Virchow-Robin spaces: an anatomofunctional study.

We describe 2 patients with unusual white matter cystic dilations, which could correspond to widening of the perivascular spaces. They underwent morphologic MR imaging with tractography, functional MR imaging (fMRI), and neuropsychological evaluation. fMRI examination showed no functional reorganization of cortical areas.

Segmental omental infarction in childhood: an unusual case of left-sided location with extension into the pelvis.

Segmental omental infarction (OI) is a rare cause of abdominal pain in children. It generally occurs in the right lower and upper quadrants of the abdomen and only a few cases of other locations have been described in adults. We report a unique paediatric case of OI with an unusual left-sided location extending into the pelvis in a 6-year-old non-obese girl.

Effect of metoclopramide on maternal and fetal hyperprolactinemia.

To investigate the effect of metoclopramide (MET), a dopaminergic antagonist drug, on serum PRL concentration in maternal and cord blood (CB) serum, the drug was injected in 94 at term pregnant women whereas 28 mothers received saline. Maternal serum (MS) samples were obtained before MET injection and at the parturition time. According to the interval of time between MET administration and birth, MS specimens were grouped in 7 groups.
