Imaging of the Acutely Injured Hip

Acute hip pain following injury more commonly originates locally in and around the hip joint rather than being referred from the lumbar spine, sacroiliac joints, groin, or pelvis. Clinical assessment can usually localize the pain source to the hip region. Thereafter, imaging helps define the precise cause of acute hip pain. This review discusses the imaging of common causes of acute hip pain following injury in adults, addressing injuries in and around the hip joint. Pediatric and postsurgical causes of hip pain following injury are not discussed.

Unusual Radiological Features of a Breast Cancer Patient Presenting with Nipple Discharge in Hong Kong

A 62-year-old woman was presented with blood stained nipple discharge for many years. Mammograms and ultrasound study revealed a prominent left nipple, increase in nipple vascularity and nipple calcifications. Ductogram revealed an obstruction at the proximal part of the discharging duct. Surgical excision of the nipple demonstrated encapsulated papillary carcinoma. The excision margins appeared to be clear, but tumor tissue was found within 1 mm from the deep margin. Ultra-filtered sulfur colloid sentinel node examination was negative. Thus, simple left mastectomy was performed. The specimen was confirmed as ductal carcinoma in situ of the left breast.
