“…On ultrasound, a trichobezoar typically appears as a curvilinear, bright echogenic band which blocks transmission of sound waves, casting a shadow over the left upper quadrant, as demonstrated in this case (Fig. 1A) [11,12]. This results from the high echogenicity of hair and the presence of multiple acoustic interfaces created by trapped air and food [13].…”

“…Gastric bezoars are difficult to characterize on magnetic resonance imaging because of their characteristic low signal on all sequences and may be confused with air. 15 Upper endoscopy, in addition to being a diagnostic aid for trichobezoar, may be used for therapeutic retrieval of small proximal trichobezoars. Endoscopic fragmentation and retrieval of bezoars, with or without enzymatic dissolution, are technically challenging especially with trichobezoars, and the fragments may migrate distally to incite small-bowel obstruction.…”

Bezoars are conglomerates of food or fiber in the alimentary tract of humans and certain animals, mainly ruminants. A trichobezoar represents a mass of accumulated hair. Trichobezoars may present as an isolated gastric mass, as an extension into the small intestine, or as an independent fragmented mass in the small intestine. The presence of discrete coexisting gastric and ileal trichobezoars has been reported only rarely in the literature. This is a case report of a 9-year-old girl presenting with small-bowel obstruction secondary to synchronous trichobezoars in the stomach and ileum. The case highlights the role of imaging and importance of complete evaluation of the gastrointestinal tract at the time of surgical evacuation.
