The ultrasonographic appearance of a trichobezoar

Abstract

Bezoars are well recognized but uncommon causes of upper abdominal pain with a mass. This case report describes how ultrasonography refuted the “biochemically confirmed” erroneous diagnosis of pseudocyst of the pancreas, and also describes the ultrasonographic appearance of a trichobezoar both in vivo and post-operatively. The ultrasound appearance of a trichobezoar has not been previously reported in the literature.
