Background: Treatment of cervical internal carotid artery (ICA) stenosis has contributed to the improvement of ocular ischemic syndrome. However, there have been few cases of visual impairment caused by ocular ischemic syndrome due to intracranial ICA stenosis, which improved through intracranial stent placement.

Background: Rosai-Dorfman disease (RDD) is a rare non-Langerhans cell histiocytic proliferative disorder classically as a massive cervical lymphadenopathy. However, over the years, extranodal locations were confirmed with the central nervous system involvement in less than 5% of cases, which is marked as a significant differential diagnosis of meningiomas, with which they are widely confused due to the similarity of their radiological images.

Background: Hemangioblastomas are benign (World Health Organization Grade I), highly vascular neoplasms commonly associated with Von Hippel-Lindau (VHL) disease.[2] The VHL tumor-suppressor gene, located on chromosome 3, is implicated in sporadic cases and cases associated with VHL disease. Hemangioblastomas most commonly arise in the posterior fossa; however, they may also be found supratentorially or within the spinal cord.[3] Surgical intervention is indicated for symptomatic lesions with a goal of complete resection of the enhancing nodule.[1]

Background: Intracranial meningioma resection is associated with substantial intraoperative bleeding. Intraoperative tranexamic acid (TXA) use can reduce bleeding in a variety of surgical procedures. The objective of this study was to evaluate the effects of TXA treatment on blood loss and transfusion requirements in patient undergoing resection of intracranial meningioma.
