Endovascular technique simulator for Neuroradiology learning.

Background: Vascular cerebral infarction (or stroke) is recognized as the third leading cause of death worldwide, and acute arterial occlusion comprises the main mechanism underlying ischemic stroke. Cerebrovascular diseases are treated by intracranial endovascular interventions employing minimally invasive intravascular techniques, such as neuroimaging. Conducting practical training in this area is a necessary task since patient safety is a considerably significant factor.

Association of Severe Hydrocephalus With Congenital Zika Syndrome.

Importance: Hydrocephalus is a treatable but potentially fatal complication that has not been previously described in congenital Zika syndrome (CZS).

Objective: To describe the clinical features and imaging findings in 24 patients with congenital Zika syndrome (CZS) who developed hydrocephalus.

Design, Setting, And Participants: This case series included patients with hydrocephalus who were born in October and November 2015 and followed up until mid-2017 in the 2 largest national referral centers for CZS in Brazil.

Impact of the Canonical Wnt Pathway Activation on the Pathogenesis and Prognosis of Adamantinomatous Craniopharyngiomas.

mutations and abnormal β-catenin distribution are associated with the pathogenesis of adamantinomatous craniopharyngioma (aCP). We evaluated the expression of the canonical Wnt pathway components in aCPs and its association with mutations and tumor progression. Tumor samples from 14 aCP patients and normal anterior pituitary samples from eight individuals without pituitary disease were studied.

Clinical and cytogenetic analysis of an intracranial inflammatory myofibroblastic tumor induced by a ventriculoperitoneal shunt.

The authors report the first case of an intracranial inflammatory myofibroblastic tumor (IMT) associated with the placement of a ventriculoperitoneal shunt, which occurred in a 7-year-old boy. Neuroradiological features showed a mass surrounding the ventricular catheter. The lesion was completely resected.

Hydrocephalus in posterior fossa tumors in children. Are there factors that determine a need for permanent cerebrospinal fluid diversion?

Objective: We searched for factors that could predispose towards persistent hydrocephalus in children with posterior fossa (PF) tumors in order to determine the need for permanent cerebrospinal fluid (CSF) diversion.

Methods: The clinical records of 64 children who underwent surgery for PF tumors in the Pediatric Neurosurgery division of the Hospital of Clinics, Ribeirao Preto, Brazil, from 1990 to 2006, were retrospectively reviewed. The patients' ages ranged from 3 months to 18 years.

Aplasia cutis congenita of the scalp: is there a better treatment strategy?

Background: Aplasia cutis congenita (ACC) is a rare disease of unknown etiology, involving any site of the body. The scalp is the most frequent location, followed by the forearms, knees, both sides of the trunk, and neck, in decreasing order of frequency. Superficial lesions may heal spontaneously and seldom result in morbidity or mortality.
