A Rare Presentation of Intracerebellar Schwannoma: A Case Report.

Intracerebellar schwannoma is an extremely rare disease entity with only 21 case reports described in the literature. A 68-year-old male presented with chronic headaches, dizziness, gait imbalance, and incoordination. Previous MRI had revealed a cystic lesion in the right cerebellum; however, patient was lost to follow-up.

Traumatic penetrating head injury by crossbow projectiles: A case report and literature review.

Background: Low-energy penetrating head injuries caused by arrows are relatively uncommon. The objective of this report is to describe a case presentation and management of self-inflicted intracranial injury using a crossbow and to provide a relevant literature review.

Case Report: A 31-year-old man with a previous psychiatric history sustained a self-inflicted injury using a crossbow that he bought from a department store.

Rates of cerebrospinal fluid leak and pseudomeningocele formation after posterior fossa craniotomy versus craniectomy: A systematic review and meta-analysis.

Background: Postoperative cerebrospinal fluid (CSF) leak is a major concern after posterior fossa surgery with significant clinical implications. It has been postulated that replacing the bone flap, performing a craniotomy, would reinforce the surgical closure and decrease rates of CSF leak. This systematic review and meta-analysis compared the rate of CSF leak after posterior fossa craniotomies versus craniectomies.

Case Report: Endovascular Treatment of a Giant Distal PICA Aneurysm in Association With a Cerebellar AVM: A Report on Treatment Considerations and a Literature Review.

Distal posterior inferior cerebellar artery (PICA) aneurysms are uncommon intracranial vascular lesions. The coincidence of these aneurysms and Arteriovenous malformation (AVM) is even more rare. Since 1956, a total of 57 cases of distal PICA aneurysms associated with AVM have been reported with clear and adequate description.

Surgical Management of Isolated Fourth Ventricular Hydrocephalus Associated with Injury to the Guillain-Mollaret Triangle.

Background: The occurrence of isolated fourth ventricle and injury to the Guillain-Mollaret triangle in the setting of posterior fossa ependymoma represents a new association. In this case report, we discuss the clinical, theoretical, and therapeutic aspects of this problem. We describe a lateral transcerebellar trajectory and shunt valve configuration for safe fourth ventricle shunting in a patient with prior posterior fossa surgery.

Pure Endovascular Management of an Arteriovenous Malformation and an Aneurysm Both Supplied by Anterio-Inferior Cerebellar Artery: A Case Report and a Review of Literature.

Background And Importance: The tendency of posterior fossa arteriovenous malformations (pfAVM) to develop associated aneurysms (AA) is a well-known phenomenon with an increased total risk of rupture. Most pfAVM and AA develop in the territory of the posterior inferior cerebellar artery while the involvement of the anterior inferior cerebellar artery (AICA) is extremely rare. We describe an unusual case of an arteriovenous malformation (AVM) supplied by the AICA with a "proximal" AA.

Characteristics and management of mirror syndrome: a systematic review (1956-2016).

Objectives: To describe the clinical features of mirror syndrome and to correlate the effects of different treatments with the fetal outcomes.

Data Sources: Online search up to May 2016 was conducted in the PubMed, Embase (Ovid platform) and clinicalTrials.gov without restrictions of language, date or journal.

A delayed presentation of homozygous protein C deficiency in a series of children: a report on two molecular defects.

Pediatric emergency visits with purpura fulminans should raise the suspicion of hereditary homozygous protein C deficiency even beyond the neonatal age. The absence of this classical finding does not role the diagnosis out as atypical presentation with isolated intraocular bleeding was observed. Premarital counseling should be offered when family history suggests.

Peters Anomaly in Twins: A Case Report of a Rare Incident with Novel Comorbidities.

Introduction: Peters anomaly is a rare developmental malformation involving the anterior segment of the eye, which culminates in amblyopia or congenital blindness. Multiple ocular and/or systemic malformations have been observed with this anomaly, and novel comorbidities continue to be reported.

Case Presentation: The probands were monozygotic twin boys (twin I and twin II) born to consanguineous parents at 36 weeks of gestation.
