Wunderlich syndrome (WS) refers to spontaneous renal or perinephric hemorrhage occurring in the absence of known trauma. WS is much less common than hemorrhage occurring after iatrogenic or traumatic conditions. Lenk's triad of acute onset flank pain, flank mass and hypovolemic shock is a classic presentation of Wunderlich syndrome but seen in less...

Endoscopic Retrograde Cholangiopancreatography (ERCP) remains the conventional method of imaging the pancreatic and biliary tree and is performed by direct injection of iodinated contrast material via the major papilla. This diagnostic procedure gained popularity in the 1970s and subsequently paved way for ERCP guided interventions such as sphincte...

Objective: "Curbside consults" are informal opinions provided by one physician to another. In radiology, it often refers to opinions rendered on imaging performed at outside facilities and has evolved from being a targeted response to a discrete clinical question to a complete over-read in recent years. Given that the consults are usually sought f...

Dementia is a global health issue, the burden of which will worsen with an increasingly aging population. Alzheimer's disease (AD) is the most common dementia, with 50 to 60% of all dementias attributable to AD alone, while the rest are mostly due to frontotemporal lobar dementia, dementia with Lewy bodies, Parkinson's disease dementia, and vascula...

The incidence of blunt cerebrovascular injury in trauma patients presenting with cervical spine fracture

The incidence of multiple gestations is increasing with rising maternal age and the utilization of artificial reproductive techniques. Twinning confers an increased risk to the pregnancy, with higher incidence of structural anomalies, preterm delivery, and perinatal morbidity and mortality. Certain conditions are unique to twin pregnancy, such as t...

Introduction: Adrenocortical carcinoma (ACC) is a heterogeneous and rare disease. At presentation or at the time of a recurrence, the disease commonly spreads to the liver, lungs, lymph nodes, and bones. The brain has only rarely been reported as a site of metastases. Objective: The aims of this report were to describe the clinical characteristi...

This article is the first portion of a two-part review that illustrates the normal appearance of the cerebellum and posterior fossa on prenatal ultrasound and MRI and on postnatal diagnostic imaging studies. Classification and terminology of posterior fossa abnormalities in the literature are confusing due to evolution of concepts and sometimes lac...

This second portion of a two-part review illustrates examples of posterior fossa disorders detectable on prenatal ultrasound and MRI, with postnatal or pathology correlation where available. These disorders are discussed in the context of an anatomic classification scheme described in Part 1 of this posterior fossa anomaly review. Assessment of the...

PURPOSE/AIM Review relatively common and uncommon fetal GI anomalies with associated abdominal/pelvic wall abnormalities Review imaging features of these conditions with image and related pathologic correlation Review clinical approach, the need for reimaging, and the role of radiologist as a member of the multi-disciplinary team. Review algorithmi...

Magnetic resonance imaging (MRI) is an imaging modality that uses the differential spinning of protons (hydrogen) in the body when exposed to an external magnetic field, to produce cross-sectional images of the body. The advent of MRI is a boon to mankind as it does not involve ionizing radiation and provides superior soft tissue contrast even with...

PURPOSE/AIM Congenital diaphragmatic hernia (CDH) affects approximately one in every 4000 live births. Numerous advances in have been made leading to improved survival. These include the identification of prenatal predictors of perinatal morbidity and mortality; the addition of new therapies and changes in neonatal care strategies. In this poster,...

PURPOSE/AIM Intraventricular and periventricular hemorrhage (IVH-PVH) is commonly seen in premature babies. Pathogenesis of IVH-PVH is multifactorial with participation of intravascular, vascular and extravascular factors. Detection of IVH-PVH and its neuro-pathologic consequences has been facilitated greatly by ultrasonography, MRI and CT. Accurat...

PURPOSE/AIM Cardiac anomalies can be isolated, but are often part of a larger picture and hint at underlying aneuploidy or syndromes. The purpose of the poster is to sensitize the viewer to contemplate the possibility of underlying syndromes when any of the specific cardiac defects are encountered. CONTENT ORGANIZATION Content organization: A: Sc...

PURPOSE/AIM Twin pregnancies are considered high risk due to the multiple associated complications.The initial step is to assign chorionicity as monochorionic twins are at higher risk.The prupose of this exhibit is to describe all aspects of antenatal imaging with respect to twin pregnancy. CONTENT ORGANIZATION 1. Zygosity & Chorionicity Dizygotic...
