Core Tip

Core Tip: Ingested fish bones appear as high-density shadows and hyperechoic structures on computed tomography and endoscopic ultrasonography scans. Patients typically present with symptoms or positive findings on ancillary examinations. Herein, we present a case of a fish bone hidden in the submucosal protuberance of the gastric antrum without the usual positive signs. In this rare case, we identified the reasons for the fish bone being overlooked in the diagnosis process. This report could potentially prevent the future oversight of embedded fish bones and associated adverse effects.
