The purposes of our educational exhibit are to: • Review and describe the main features of bezoars in the gastrointestinal tract; • Help radiologists to remember some typical abdominal CT and MR findings; • Describe cases with the most significant radiological features,
contributing to the correct diagnosis.
Bezoars are an accumulation of ingested materials that are not digested and remain in the gastrointestinal tract,
being classified according to the types of materials with which they are formed.
They constitute a rare cause of intestinal obstruction and the knowledge of its imaging characteristics is essential in the diagnostic process and aids the management decision.
Ultrasonography can be used as a screening method however,
Computed Tomography (CT) imaging allows a better characterization...
Findings and procedure details
The cases presented in this study were selected from our institution’s teaching filesat an University Hospital (Instituto de Medicina Integral Prof.
Fernando Figueira - IMIP) and show CT images of bezoars in the gastrointestinal tract. INTRODUTION The presence of bezoar in the gastrointestinal tract is rare and its true incidence is not known,
but they must be properly diagnosed and treated.
Bezoar consists of a compaction of exogenous material that can be found especially in the...
The study combines the typical features of bezoars
the occurrence of bezoar may be a cause of
obstruction of the intestinal tract and can be demonstrate may present as a non-specific image.
knowledge and familiarity with the broad spectrum of intra-abdominal foreign bodies that can be detected by imaging is important to establish the correct diagnosis,
the nature of a foreign body,
and allows rapid intervention if necessary.
