ABSTRACT
The presence of a foreign body in the periapical tissues can cause endodontic failure by triggering an inflammatory response and a subsequent foreign body reaction. This inflammatory response, which can occur to varying degrees, appears radiographically as a radiolucency that can remain asymptomatic for many years. A foreign object can reach the apical region by accident or iatrogenic procedures during dental procedures. The aim of the present case report is to describe the endodontic surgical treatment of an iatrogenic displacement of a foreign body (a metal fragment) into the periapical tissues and to describe its clinical and radiographic follow-up over a period of 52 months.

A 50-year-old woman with jaw pain and a history of bisphosphonate use was shown on radiography to have ill-defined soft tissue calcifications overlying the maxilla, mandible, and zygomatic bones bilaterally. The bones were normal. CT revealed similar findings. Although a broad imaging differential diagnosis was initially considered, further questioning of the patient revealed a history of facial injections with a calcium hydroxylapatite product for cosmetic purposes. The appearance of this increasingly popular treatment should be recognized to avoid errors in interpretation.

To define more clearly the relationship between the information provided by the chest radiograph (CXR) and the natriuretic peptide (NT-proBNP) test as part of the evaluation of dyspneic patients presenting to the emergency department with suspected acute heart failure (HF), we evaluated the PRIDE cohort of 599 patients with and without HF, focusing on blinded NT-proBNP and unblinded CXR information. Clinical characteristics and diagnostic performance for each test were compared. We found that NT-proBNP measurement is superior to routine CXR interpretation for diagnosis or exclusion of acute HF and that normal CXR results should not be used to exclude HF in this population.

Magnetic resonance imaging (MRI) is an invaluable tool for evaluating traumatic injuries of the shoulder. This article discusses MRI of shoulder trauma based on mechanism of injury. Acute direct traumatic injuries, acute indirect traumatic injuries, and repetitive microtraumatic injuries (impingement/traction) are discussed. Finally, common pitfalls in shoulder imaging are addressed.
