Three cases of trichobezoar (12/F, 5/F, and 35/M) are reported. All patients presented with an epigastric mass and the diagnosis was not suspected clinically. They were referred for sonography which revealed a hyperechoic curvilinear dense strip at the anterior margin of the lesion associated with marked acoustic shadowing and no through transmission. Similar findings were noted in all three cases. In vitro ultrasound scans performed on the operated specimen in one case confirmed that the sonographic findings were the result of the trichobezoar mass. Diagnosis was confirmed in all the cases by barium meal and surgery.
