Abstract:
This case report describes a previously healthy pediatric patient with acute onset of abdominal pain and distention who was found to have an epigastric mass on physical examination. Point-of-care ultrasound (POCUS) demonstrated a large gastric mass with ultrasonographic features consistent with a trichobezoar. After POCUS was performed, trichophagia was confirmed on history, and the patient went to the operating room for removal of a large trichobezoar. We conclude POCUS may be helpful for evaluation of epigastric masses and diagnosis of gastric trichobezoars. We review the ultrasound technique, sonographic findings, and literature regarding ultrasound diagnosis of trichobezoars.
