Pitfalls in imaging of musculoskeletal infections.

In musculoskeletal infections, imaging helps in the diagnosis and identification of disease extent. Musculoskeletal infections have variable clinical presentations related to host immune responses and virulence of pathogens. Occasionally, infectious process may mimic other entities such as autoimmune inflammatory diseases, tumors, or traumatic injuries, both clinically and radiologically.

Clinics in diagnostic imaging (149). Bilateral testicular epidermoid cysts.

A 33-year-old man presented with a painless, non-growing left testicular mass for five years. Preoperative ultrasonography (US) of the scrotum showed a small, circumscribed calcific mass in the right testis and another well-defined heterogeneous echoic mass with a partially calcified wall in the left testis, with avascularity on colour Doppler US. These imaging findings in a clinical setting of non-growing testicular masses were highly suggestive of epidermoid cysts, thus leading to testis sparing surgery.

Congenital renal anomalies detected in adulthood.

Objective: To document the types of congenital renal anomalies detected in adulthood, the clinical presentation and complications of these renal anomalies, and the most useful imaging modality in detecting a renal anomaly.

Materials And Methods: This study was approved by the institutional review board and informed consent was waived. Between January 2007 and January 2011, the clinical data and imaging studies of 28 patients older than 18 years diagnosed with renal anomaly at the authors' institution were retrospectively reviewed.

Paget's disease of the breast: clinical, imaging and pathologic findings: a review of 16 patients.

Objectives: To determine the clinical, imaging and pathological findings of Paget's disease of the breast.

Materials And Methods: Approval by Institutional Review Board was granted and informed consent was waived. Retrospective review of the pathological diagnosis of 2,361 women with breast carcinoma between January 2004 and April 2010 revealed 27 patients with Paget's disease of the breast.

Musculoskeletal melioidosis.

Melioidosis is an infectious disease caused by Burkholderia pseudomallei, mostly affecting patients in Southeast Asia and northern Australia. The disease has been increasingly recognized around the world due to the increased levels of travel and population movement. Clinical manifestations of melioidosis range from fulminant septicemic illness to an indolent local infection.
