Clinics in diagnostic imaging (104): Gastric trichobezoar (or hairball).
A 56-year-old man underwent triphasic computed tomography (CT) of the abdomen as part of his work-up for liver transplantation. A mottled, rounded lesion with a dense rim was noted in the gastric lumen, which remained unchanged in appearance in the arterial, portal venous, and delayed phases of the CT. Gastroscopy performed three days later confirmed the presence of trichobezoar. The foreign body was broken down into smaller pieces by an endoscopic snare and was passed out spontaneously. The clinical presentation, radiological findings, and management of trichobezoars are discussed.
