Abstract
Inguinal hernia repair (IHR) with prosthetic mesh implantation is the most common procedure in general surgery, and may be performed using either an open or laparoscopic approach. This paper provides an overview of contemporary tension-free IHR techniques and materials, and illustrates the expected postoperative imaging findings and iatrogenic injuries. Emphasis is placed on multidetector CT, which represents the ideal modality to comprehensively visualize the operated groin region and deeper intra-abdominal structures. CT consistently depicts seroma, mesh infections, hemorrhages, bowel complications and urinary bladder injuries, and thus generally provides a consistent basis for therapeutic choice. Since radiologists are increasingly requested to investigate suspected iatrogenic complications, this paper aims to provide an increased familiarity with early CT studies after IHR, including complications and normal postoperative appearances such as focal pseudolesions, in order to avoid misinterpretation and inappropriate management.

Abstract
An 84-year-old man with history of left forehead melanoma was found on a restaging F-FDG PET/CT scan with hypermetabolic lung nodules and a mildly FDG-avid soft tissue nodule posterior to the umbilicus. Biopsy of a right lower lobe nodule revealed metastatic melanoma. Follow-up posttreatment PET/CT scan showed complete resolution of lung nodules and unchanged FDG uptake at the level of the umbilicus. Review of the patient's medical history revealed a remote history of umbilical hernia repair. We present a case of postsurgical plugoma mimicking the appearance of melanoma metastasis on FDG PET/CT.

Abstract
PURPOSE The radiologist can encounter benign significant imaging findings on computed tomography that can be incorrectly interpreted as neoplasm. The authors review several benign findings and demonstrate several methods to differentiate these findings from more sinister pathology. CONCLUSION It is imperative for the radiologist to be cognizant of and how to correctly identify mimickers of pathology so that unnecessary interventions and surgeries are avoided.

Abstract
Foreign objects are not infrequently seen at computed tomography (CT) of the abdomen and pelvis and may pose a diagnostic challenge to the radiologist, who must recognize the object, characterize its nature and location, and determine its clinical significance. Most foreign objects are incidentally detected at CT, but they may mimic a wide range of pathologic conditions. Some foreign objects (eg, an object that has been swallowed either intentionally or unintentionally) are the cause of the patient's signs and symptoms and require prompt medical attention. Other objects, such as a sponge or surgical instrument that has been retained postoperatively, may have medicolegal consequences. Furthermore, certain objects, such as intentionally concealed drug packets, may go undetected unless a high degree of suspicion exists and appropriate window settings are used to review the study. The radiologist should be familiar with the wide range of foreign objects that may be encountered at abdominopelvic CT, be able to recognize them promptly, and understand their implications for patient treatment.

Abstract
BACKGROUND Synthetic mesh is used commonly in the repair of abdominal wall hernias. Infection at the surgical site where mesh is present poses a formidable clinical problem. METHODS The current surgical literature was reviewed to formulate accepted approaches to the management of hernia repairs with infected mesh. RESULTS Prevention of mesh infection is best achieved by judicious use of systemic antibiotics. Topical antibiotics often are used without convincing evidence to support their value. Laparoscopic repairs have lower infection rates than open repairs. Evidence is lacking to support lower rates of infection with mesh of specific composition or with antibacterial agents that coat the mesh. The diagnosis of mesh infection is principally a clinical one. Repairs of infected mesh usually necessitate antibiotics and removal of the foreign material. Clinical judgment is required for attempts at salvaging portions of the mesh. Component separation or biological materials may be used in those circumstances for hernia repair in which large defects are created by removal of the infected synthetic material. CONCLUSIONS Prevention of mesh infections remains the best strategy. Clinical judgment is essential in determining the degree of mesh removal. Continued clinical studies are necessary to improve the outcomes of established mesh infection in hernia repairs.
