[Ruptured Spinal Arteriovenous Malformation Mimicking Bacterial Meningitis:A Case Report].

A 23-year-old woman was referred to our hospital with progressive headache and back pain. Cerebrospinal fluid(CSF)analysis revealed hypoglycorrhachia and pleocytosis. However, imaging studies did not reveal evidence of subarachnoid hemorrhage(SAH), and she was diagnosed with bacterial meningitis.

[A Case of Pediatric C1 Dysplasia with Ruptured Aneurysm in Collateral Plexiform Arterial Network].

A 3-year-old girl was admitted to our hospital with symptoms including headache, nausea, and vomiting. Head CT scan showed subarachnoid hemorrhage in the right carotid cistern. Digital subtraction angiography revealed right internal caortid artery(ICA)malformation at the C1 segment with collateral plexiform arterial network.

A case report of CIC-rearranged undifferentiated small round cell sarcoma in the cerebrum.

CIC-rearranged undifferentiated small round cell sarcoma (CIC-rearranged USRCS) is a recently established type of Ewing-like small round cell sarcomas, characterized by CIC gene rearrangement, most commonly CIC-DUX4 fusion. This report presents the second case of CIC-rearranged USRCS arising primarily in the cerebrum. A 64-year-old otherwise healthy woman presented with a 1 × 1 cm sized hemorrhagic subcortical tumor in the left temporo-parietal lobe.

[Usefulness and Problems of Intraoperative Monitoring for Unruptured Aneurysm Surgery with the Motor Evoked Potential].

It has been pointed out that the motor evoked potential(MEP)with a subdural electrode is useful in the intraoperative monitoring for unruptured aneurysm surgery. However, in some cases, we experienced postoperative ischemic complications despite evaluating the motor function via MEP monitoring. Herein, we have reported the usefulness and problems of intraoperative monitoring with MEP to evaluate brain dysfunction caused by insufficiency of cerebral blood flow.

CIC-rearranged Sarcomas: A Study of 20 Cases and Comparisons With Ewing Sarcomas.

The CIC gene rearrangement exists in a subset of small round cell sarcomas. As the nosologic relationship of these sarcomas to Ewing sarcomas remains undetermined, we examined 20 CIC-rearranged sarcomas to compare their clinicopathologic features with those of Ewing sarcomas. The CIC-rearranged sarcomas were from a group of 14 men and 6 women with a median age of 24.

Carotid angioplasty with stenting for chronic internal carotid artery occlusion: technical note.

Introduction: Carotid angioplasty with stenting (CAS) is becoming accepted as an effective and reliable treatment option for severe carotid artery stenosis. However, it is rarely applied for carotid occlusion, especially in its chronic stage. We report our experience of CAS for chronic internal carotid artery occlusion representing compromised cerebral blood flow using various protection methods.

Suppression of secondary generalization of limbic seizures by stimulation of subthalamic nucleus in rats.

Object: Deep brain stimulation (DBS) of subcortical nuclei such as the subthalamic nucleus (STN) or the substantia nigra pars reticulata (SNR) may provide an alternative therapy for intractable epilepsy. The authors attempted to evaluate the antiepileptic effects of DBS to these structures in an experimental seizure model.

Methods: Three groups of rats were prepared.

Pilomotor seizures in mesial temporal lobe epilepsy: a case confirmed by intracranial EEG.

We report the first case in which intracranial EEG was used to confirm pilomotor seizures of mesial temporal origin. A 41-year-old man who had pilomotor seizures in the left arm in addition to complex partial seizures was admitted for presurgical evaluation. Intracranial EEG revealed ictal discharges in the left mesial temporal area during left pilomotor seizures.
