ABSTRACT
Posterior dislocation of the long head of the biceps tendon uncommonly occurs with traumatic shoulder injury. The diagnosis is almost always associated with anterior shoulder dislocation which often cannot be reduced. We present a case of traumatic posterior dislocation of the long head of the biceps tendon with no reported history of shoulder dislocation, but instead a rare and specific radiographic finding. The imaging features are described, the relevant literature reviewed, and salient features discussed.

Inguinal herniation of the ovary or uterus presenting as a labia majora mass is a rare congenital condition that may be complicated by strangulation, torsion, and infertility. A labial mass in a prepubertal female patient can represent an inguinal hernia, a hydrocele of the canal of Nuck, a congenital labial cyst, leiomyoma, an abscess, lipoma, or lymphangioma. With a large differential diagnosis and an often limited physical examination, imaging plays an importance diagnostic role. We present 3 cases in which a labial mass contained an ovary alone and both ovaries and the uterus. We demonstrate sonographic findings and discuss the utility of sonography in the diagnosis of genital hernias and in detecting potential complications.

The causes of leg pain in the athlete are diverse. Pain can relate to more common etiologies, such as musculotendinous injury to the hamstrings and Achilles tendon as well as stress injury to bone, with tibial stress injuries comprising the most common cause for lower leg pain in athletes. Less-common causes include chronic exertional compartment syndrome and popliteal artery entrapment syndrome, both of which cause pain as a result of muscle ischemia. Radiologic evaluation plays an important role in differentiating among the many possible causes of leg pain and is often essential in determining degree of injury as well as in documenting healing before patient return to athletic activity. With PAES and hamstring and Achilles injuries, imaging may be helpful in surgical planning as well as in determining an underlying anatomic cause for injury. Several of these conditions can be evaluated with multiple different imaging modalities. The imaging modality of choice should be selected based on the sensitivity and specificity of the imaging examination but should also be tailored to each individual patient after determining comorbidities that may preclude certain types of imaging as well as assessing the patient's ability to undergo such testing.

Prompt restoration of blood flow is the primary treatment goal in ST-segment elevation myocardial infarction to optimize clinical outcomes. The ED plays a critical role in rapid triage, diagnosis, and management of ST-elevation myocardial infarction, and in the decision about which of the 2 recommended reperfusion options, that is, pharmacologic and mechanical (catheter-based) strategies, to undertake. Guidelines recommend percutaneous coronary intervention (PCI) if the medical contact-to-balloon time can be kept under 90 minutes, and timely administration of fibrinolytics if greater than 90 minutes. Most US hospitals do not have PCI facilities, which means the decision becomes whether to treat with a fibrinolytic agent, transfer, or both, followed by PCI if needed. Whichever reperfusion approach is used, successful treatment depends on the ED having an integrated and efficient protocol that is followed with haste. Protocols should be regularly reviewed to accommodate changes in clinical practice arising from ongoing clinical trials.
