Case: An 88-year-old female with Alzheimer's-type dementia who mis-swallowed a press-through package visited our emergency department. Outcome: Plain radiography detected no foreign bodies, whereas plain computed tomography showed an elliptical body with a high density in the lower esophagus. The press-through package containing a tablet in the esophagogastric junction was successfully removed without severe complications using the endoscopic protector hood. In cases of press-through package mis-swallowing, it is important for emergency physicians to make an early and correct diagnosis of the location of the package, which shows high radiolucency. Based on the results of this case, we hypothesize that carrying out early computed tomography examinations is useful for identifying swallowed press-through packages. Our retrospective investigation showed that computed tomography has a sensitivity of 100% for detecting press-through packages. Conclusion: We experienced a case of press-through package mis-swallowing diagnosed on computed tomography. We recommend performing computed tomography examinations, especially in patients with an uncertain history and unclear symptoms.
