title: Calcification of the posterior cricoid lamina simulating a foreign body in the aerodigestive tract (2005:11b).
abstract: This interpretation corner case, reporting a man with suspicion of ingestion and perforation of the oesophagus by a foreign body, highlights the danger of false appearances on plain radiographs for detection of foreign bodies in the aerodigestive tract. Plain radiographs and CT revealed a needle-shaped calcified object between the cricoid plate and the oesophagus lumen, which turned out to be an abnormal cricoid calcification. There is also a discussion about the role of radiology in the detection of foreign bodies in the aerodigestive tract.
