An Update and Comprehensive Review of the Posterolateral Corner of the Knee.

The posterolateral corner (PLC) of the knee is composed of numerous ligamentous and tendinous structures that provide restraint and stability. This anatomy is complex, and at times controversial. We present a comprehensive review of the normal anatomy and pathology of the PLC.

Turf Toe: An Update and Comprehensive Review.

Turf toe is a spectrum of injury involving the first metatarsophalangeal joint originally described in football players on artificial surfaces. A detailed description of the complex anatomy and pathology involved in the turf toe injury is presented. We highlight potential pitfalls of image interpretation and emphasize what the referring physician needs to know.

Traumatic lipohemobursa of the infrapatellar bursa.

Displaced fractures allow spillage of bone marrow and blood into the surrounding soft tissues. When the fracture is intra-articular, the spilled marrow contents may be contained by the associated joint capsule, resulting in a lipohemarthrosis. This is sometimes visible as a fat-fluid level on imaging.

Use of whole body CT to detect patterns of CPR-related injuries after sudden cardiac arrest.

Aims And Objectives: We have recently implemented a dedicated sudden cardiac arrest (SCA) - whole-body computed tomography (WBCT) protocol to evaluate SCA patients with return of spontaneous circulation (ROSC) following cardiopulmonary resuscitation (CPR). The aim of this study is to evaluate the number and pattern of CPR-related injuries in ROSC patients with SCA-WBCT.

Methods And Materials: Single-centre retrospective review of 39 patients (13 female; 20 male, mean age 51.

ASER core curriculum illustration project: aortic intramural hematoma (IMH).

This is the 23rd installment of a series that will highlight one case per publication issue from the bank of cases available online as part of the American Society of Emergency Radiology (ASER) educational resources. Our goal is to generate more interest in and use of our online materials. To view more cases online, please visit the ASER Core Curriculum and Recommendations for Study online at http://www.

Finding the Nidus: Detection and Workup of Non-Central Nervous System Arteriovenous Malformations.

Vascular anomalies are a diverse group of pathologic conditions. They have different manifestations, natural histories, and treatments. Compared with other vascular malformations, arteriovenous malformations (AVMs) are considered the most symptomatic and difficult to manage.

Clinical implications for imaging of vascular invasion in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the second largest cause of cancer mortality in the world, with vascular invasion being one of the most important prognostic factors. HCC with tumor thrombus was traditionally considered to have very limited treatment options. However, multiple promising treatment strategies have emerged in recent years, with diagnostic and interventional radiologists playing a major role in patient management.

Balloon tamponade repair after inadvertent subclavian artery catheterization.

Purpose: The approach to repair inadvertent subclavian artery catheterization has evolved to increasingly less invasive modalities. Most recently, endovascular balloon tamponade has become the preferred initial approach. We report our experience and review the technique.
