Abdominal manifestations of fishbone perforation: a pictorial essay

Abstract

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.

Gastrointestinal perforation: clinical and MDCT clues for identification of aetiology

“…In blunt trauma, an added late 3-5-min phase is needed to exclude low-flow active bleeding [3,13]. Review of images in multiple window settings is indispensable, since extraluminal air and foreign bodies are better visualised in lung and bone window settings, respectively [2,[6][7][8][9][10][11][12][14][15][16][17][18]. Multiplanar reformations can greatly increase the accuracy in localisation of perforation site [2,[6][7][8][9][10][11][12][14][15][16][17][18].…”

“…Less than 1% of cases of ingested foreign bodies lead to perforation [16,18]. Some patients may not recall ingesting a foreign body, present with nonspecific symptoms and may be diagnosed months or years later [16].…”

“…Less than 1% of cases of ingested foreign bodies lead to perforation [16,18]. Some patients may not recall ingesting a foreign body, present with nonspecific symptoms and may be diagnosed months or years later [16]. Patients at higher risk are those with reduced palate sensitivity (use of dentures), alcohol abuse, young children, elderly and mentally handicapped [16,18].…”

A foreign body may be radiopaque depending on its composition [18].…”

“…A foreign body may be radiopaque depending on its composition [18]. Fish bones are the most common culprit throughout the GIT except for the oesophagus and usually result in contained perforations which are sealed off by surrounding omentum and inflammation [16]. Consequently, associated pneumoperitoneum is uncommon [16,18].…”
