Computed tomography appearance of ovarian cysts with hyperenhancing rim during the menstrual cycle in women of different ages.

Objective: To determine the frequency and computed tomography (CT) characteristics of ovarian cysts in women of different ages.

Methods: Five hundred ninety-five contrast-enhanced CT studies performed in 430 females aged 10 or older between January 2001 and December 2006 were retrospectively reviewed. For each study, we recorded the presence of ovarian cysts larger than 5 mm in diameter, with or without a hyperenhancing rim (HR, NR).

Aberrant right hepatic arterial anatomy and pancreaticoduodenectomy: recognition, prevalence and management.

Background: Aberrant arterial anatomy is a common finding during foregut surgery. Anomalies to the right hepatic lobe are especially relevant during pancreaticoduodenectomy (PD) and their recognition serves to protect the blood supply to the liver and bile ducts. We report our experience with aberrant right hepatic arterial anatomy (ARHAA) found during PD.
