Foreign-body ingestion is a rare cause for acute appendicitis. The authors report a case of a 48-year-old man who presented with abdominal pain for 3 days. Computed tomography (CT) revealed a foreign body in the appendix with peri-appendicular inflammatory changes. The patient underwent a successful appendectomy with complete recovery.

Abstract Introduction We aim to evaluate the frequency of use and changing practices for all out-of-hours interventional radiology (IR) procedures performed in a new hospital. Methods This is a 5 year retrospective review of all out-of-hours procedures performed by the Interventional Radiology team from July 2010 to June 2015. Number and category of procedures performed were identified from the RIS database. Results Of the 7140 procedures performed by IR over the 5 years, 764 were out-of-hours. The total number of out-of-hours cases performed annually by IR has increased by 240% from year 1 to year 5. The variety and distribution of out-of-hours work has shown a characteristic trend with rising requests for advanced procedures such as active haemorrhage control. Conclusion The rising number and complexity of cases for on-call IR further supports the need for a formal on-call rota, ideally 1:6, to provide a sustainable 24/7 service and optimize patient outcome in an acute hospital.

The skull base anatomy is complex. Numerous vital neurovascular structures pass through multiple channels and foramina located in the base skull. With the advent of computerized tomography (CT) and magnetic resonance imaging (MRI), accurate preoperative lesion localization and evaluation of its relationship with adjacent neurovascular structures is possible. It is imperative that the radiologist and skull base surgeons are familiar with this complex anatomy for localizing the skull base lesion, reaching appropriate differential diagnosis, and deciding the optimal surgical approach. CT and MRI are complementary to each other and are often used together for the demonstration of the full disease extent. This article focuses on the radiological anatomy of the skull base and discusses few of the common pathologies affecting the skull base.

Ascaris lumbricoides is the most common helminth affecting humans. Ascariasis can result in serious complications, including intestinal obstruction and perforation. Early diagnosis and treatment of such complications reduces the risk of mortality. We present a case of sonographically diagnosed ascaridial perforation in a 5-year-old girl. On sonography, each ascarid appeared as 2 pairs of parallel lines, representing the worm's outer margins, flanking a central sonolucent line, representing its digestive tract. Sonography revealed ascarides in the peritoneal cavity and in some loops of the small bowel. Emergent laparotomy was performed to remove ascarides from the peritoneal cavity and terminal ileum, and the patient recovered well and was asymptomatic at a 3-month follow-up. Knowledge of the sonographic features described herein may aid in the evaluation of patients, especially children, in tropical countries who have clinical symptoms of ascariasis. © 2003 Wiley Periodicals, Inc. 31:211–213, 2003 [ABSTRACT FROM AUTHOR]
