OBJECT Arachnoid cysts are a frequent finding on intracranial imaging in children. The prevalence and natural history of these cysts are not well defined. The authors studied a large consecutive series of children undergoing MR imaging to better define both the MR imaging-demonstrated prevalence and behavior of these lesions over time. METHODS The authors(More)
OBJECT Arachnoid cysts are a frequent finding on intracranial imaging. The prevalence and natural history of these cysts in adults are not well defined. METHODS We retrospectively reviewed the electronic medical records of a consecutive series of adults who underwent brain MRI over a 12-year interval to identify those with arachnoid cysts. The MRI studies(More)
OBJECT We reviewed our experience with pineal cysts to define the natural history and clinical relevance of this common intracranial finding. METHODS The study population consisted of 48,417 consecutive patients who underwent brain MR imaging at a single institution over a 12-year interval and who were over 18 years of age at the time of imaging. Patient(More)
OBJECT Pineal cysts are a frequent incidental finding on intracranial imaging. In adults, the prevalence of pineal cysts is estimated to be 1.1-4.3%. However, the prevalence is not well established in younger patients. METHODS The authors retrospectively reviewed a consecutive series of 14,516 patients 25 years of age and younger, who underwent brain MR(More)
OBJECT The authors reviewed their experience with pediatric pineal cysts to define the natural history and clinical relevance of this common intracranial finding. METHODS The authors identified all patients with pineal cysts who had been clinically evaluated at their institution over an 11.5-year interval and were < 25 years of age at the time of(More)
OBJECT After primary repair of a myelomeningocele or a lipomyelomeningocele, patients can present with symptoms of secondary tethered cord syndrome (TCS). After surgical untethering, a small percentage of these patients can present with multiple repeat TCS. In patients presenting with secondary or multiple repeat TCS, the role as well the expected outcomes(More)
Polyuria is common in the period immediately following the renal transplantation [1]. Such postoperative polyuria, which is associated with renal tubular dysfunction, can be exacerbated by aggressive i.v. fluid resuscitation [2]. With prolonged high volume polyuria, proper medical management may be difficult as fluid and electrolyte balance may be(More)
Craniocervical arterial dissections (CCADs) represent a preventable cause of acute ischemic stroke (AIS). Our objective was to describe clinical presentation, imaging features, treatment strategies, and report clinical and imaging outcomes of CCADs at a large pediatric tertiary referral center. Electronic medical records were queried using variations of the(More)
OBJECT The authors conducted a study to review outcomes and management in patients in whom intracranial hemorrhage (ICH) develops during left ventricular assist device (LVAD) therapy. METHODS This retrospective cohort study included all adult patients (18 years of age or older) at a single institution who underwent placement of an LVAD between January 1,(More)
OBJECT This study was undertaken to define the age-related prevalence of cavernous malformations (CMs) in children and young adults undergoing intracranial imaging. In addition, the authors aim to clarify the natural history of CMs in young people, especially in those with incidentally discovered lesions. METHODS To identify those patients with CMs, the(More)
