The evolution of pituitary cysts in growth hormone-treated children.

Objectives: We have previously shown that pituitary cysts may affect growth hormone secretion. This study sought to determine cyst evolution during growth hormone treatment in children.

Methods: Forty-nine patients with short stature, a pituitary cyst, and at least two brain MRI scans were included.

Placement of Ommaya Reservoirs Using Electromagnetic Neuronavigation and Neuroendoscopy: A Retrospective Study with Cost-Benefit Analysis.

Background: Placement of intraventricular catheters in oncology patients is associated with high complication rates. Placing Ommaya reservoirs with the zero-error precision protocol (ZEPP), a combination of neuronavigation (AxiEM stereotactic navigation) and direct verification of catheter tip placement with a flexible neuroendoscope, is associated with decreased complication rates as a result of increased catheter placement accuracy. However, the ZEPP costs more than traditional methods of catheter placement, and the question of whether this increased accuracy with the ZEPP is cost-effective is unknown.

The prevalence and volumetry of pituitary cysts in children with growth hormone deficiency and idiopathic short stature.

Background Pituitary cysts have been speculated to cause endocrinopathies. We sought to describe the prevalence and volumetry of pituitary cysts in patients with growth hormone deficiency (GHD) and idiopathic short stature (ISS). Methods Six hundred and eighteen children evaluated for growth failure at the Division of Pediatric Endocrinology at New York Medical College between the years 2002 and 2012, who underwent GH stimulation testing and had a brain magnetic resonance imaging (MRI) prior to initiating GH treatment were randomly selected to be a part of this study.

Basilar Artery Herniation into the Sphenoid Sinus Secondary to Traumatic Skull Base Fractures: Case Report and Review of the Literature.

Background: Traumatic clival fractures occur with less than 0.6% frequency and can be associated with significant neurovascular injuries. The most serious of these injuries is to the basilar artery in which the artery is dissected or is fully occluded, resulting in infarction of the brainstem and cerebellum.

Pituitary volume in children with growth hormone deficiency, idiopathic short stature and controls.

Background: The objective of the study was to describe the pituitary volume (PV) in pediatric patients with isolated growth hormone deficiency (IGHD), idiopathic short stature (ISS) and normal controls.

Methods: Sixty-nine patients (57 male, 12 female), with a mean age of 11.9 (±2.
