Description
Summary:Purpose The present article provides an overview of the spectrum of abdominal presentations of fishbone (FB) ingestion and its complications. Methods In image data from 9 patients, FB perforations were found in different levels of the gastrointestinal tract (GIT), including duodenal, jejunal, and sigmoid perforations; in 4 asymptomatic patients, FBs were observed in the mesentery, falciform ligament, and intestinal bowel. Results The main imaging features of FB perforation were focal gastric or intestinal wall thickening, fat stranding, bowel obstruction, ascites, localized pneumoperitoneum, intra-abdominal abscess, liver abscess, and a linear hyperdense structure in the abdominal cavity in the GIT or within a parenchymal organ often surrounded by inflammatory changes. Free pneumoperitoneum was rare. Conclusion Although in most cases, a FB does not cause any serious complications, an inflammatory process and complications may occur when it perforates the stomach or bowel loops. Radiologists need to be aware of the possibility of FB perforation, especially in high-risk patients, because it is not always considered in the differential diagnosis by referring physicians and can mimic other inflammatory conditions and tumoral lesions.
