Gastric obstruction from bezoar. [Abdominal] [CT]

This patient with a history of developmental delay had a dental extraction 5 days before, during which they packed the area with gauze. The patient swallowed the gauze later on and started having nausea and vomiting 1 day before coming into the emergency department.

Coronal CT images show a distended stomach and a round object in the duodenum, representing a wad of gauze, as the source of the obstruction.
