Multinodular and vacuolating neuronal tumor: A case report and literature review.

Background: Multinodular and vacuolated neuronal tumor (MVNT) is a benign neuronal tumor that is newly recognized as architectural appearance that may be related to ganglion cell tumors in 2016 World Health Organization Classification of Tumors of the Central Nervous System. Herein, we report a case of MVNT in a 60-year-old man with a thorough literature review.

Case Description: A 60-year-old male was pointed out the presence of intracerebral neoplasm located in left frontal lobe by a comprehensive medical examination.

Vascular Reconstruction for Radiation-induced Bilateral Internal Carotid Artery Occlusion and Unilateral External Carotid Artery Stenosis by a Combination of Surgical and Endovascular Method: Case Report.

We present a case of a 63-year-old male presenting with right hemiparesis and diagnosed as cerebral infarction. He had a previous history of left pharyngeal carcinoma, which was treated by radial dissection and radiation therapy 10 years before. Magnetic resonance imaging (MRI) showed multiple cerebral infarction in the bilateral cerebral hemisphere, predominantly on the left.

[MEP showed peculiar changes after temporal ICA occlusion in aneurysm surgery, in spite of cerebral tolerance to preoperative test occlusion. A case report].

Preoperative balloon test occlusion (BTO) has generally been used to predict intraoperative tolerance for temporary vascular occlusion to prevent a premature rupture during aneurysm surgery or to perform complete treatment for large aneurysms. We encountered a case in which intraoperative motor evoked potential (MEP) revealed peculiar changes after temporal occlusion of the internal carotid artery during aneurysm surgery, in spite of showing sufficient tolerance to preoperative BTO. We emphasize the importance of intraoperative MEP monitoring, even if patients have shown tolerance in preoperative BTO.

Recipient targeting for revascularization using pulsed Doppler ultrasonography for the treatment of an intracranial giant aneurysm.

Aneurysmal occlusion after blood flow revascularization is a promising management strategy for the treatment of intracranial giant aneurysms. However, it is necessary to design robust revascularization for preventing postoperative flow-related infarctions caused by abrupt occlusion of the parent vessels. Since direct anastomosis of donor vessels to recipient vessels near giant aneurysms is often difficult, it is preferable to select cortical recipient branches away from the aneurysm, thus providing a sufficient working space for the surgeon.

[A case report of a scalp dermoid cyst containing watery-clear fluid].

We report a case of a 7-month-old female with a dermoid cyst on the anterior fontanelle. She was born with a vacuum extractor. Two weeks later, her scalp on the anterior fontanelle bulged.
