The diagnostic sonography of the peripheral nervous system is a rapidly

evolving and constantly expanding imaging field in the last years, especially in patients presenting with signs of polyneuropathy. We report for the first time a correlation of the sonographic and electrophysiological findings in a patient with MMN. We draw the attention on the usefulness of ultrasonography for detecting and diagnosing segmental lesions of the peripheral nerves in MMN and other immune mediated neuropathies, especially in DNA Damage inhibitor cases where a nervous segment cannot be easily explored in terms of inching technique. “
“We present a case of intraventricular fat deposits discovered on magnetic resonance imaging and computed tomography in the absence of a ruptured dermoid cyst. The patient is a 25-year-old right-handed African-American female who previously had lumboperitoneal (LP) shunt placement for pseudotumor cerebri. She had multiple shunt-related complications that required two revisions as well as an incisional hernia repair. We suggest ABT-263 mouse that the presence of fat in her ventricles is due to retrograde flow from abdominal fat during the time when the shunt tip was located in the anterior abdominal wall as opposed to her peritoneum. Unlike ventriculoperitoneal shunts, LP shunts do not contain valves, making retrograde passage of fat possible when abdominal pressures exceed lumbar subarachnoid

pressures. The presence of these small amounts of fat in the ventricles is unlikely to cause any further symptoms in this patient, but monitoring for any Ponatinib blockage of cerebrospinal fluid flow or neurologic deterioration would be advisable. “
“A 27-year-old male presented with progressive ascending myelopathy leading to tetraparesis. Magnetic resonance imaging of the cervical spine showed dilated perimedullary veins and spinal

cord edema. Catheter angiography demonstrated a direct carotid-cavernous fistula (CCF) with prominent pontomesencephalic and perimedullary venous drainage. Successful coil embolization of the fistula was performed with improvement of the patient’s symptoms. To our knowledge, no case of a direct CCF with perimedullary drainage has been previously reported. “
“In patients with mild cognitive impairment (MCI), poor performances on delayed recall and executive function are risk factors of progression to dementia. The aim of the present study was to clarify neural correlates of these neuropsychological deficits. Thirty patients with amnestic MCI and 15 control subjects underwent neuropsychological tests including three-word delayed recall, visual delayed recall of Rey complex figure (RCF), and two-relational reasoning of Raven’s colored progressive matrices (RCPM) with a 18F-fluorodeoxyglucose (FDG)-position emission tomography (PET) measurement of resting state.
