Gastric Ulcer Revealed by Computed Tomography in a Patient with Tongue Cancer after Percutaneous Gastrostomy

With the advances in computed tomography (CT) imaging, CT can result in precise imaging, even of the gastrointestinal tract. However, the diagnostic quality of endoscopy is superior to CT because of precise mucosal observations or biopsy procedure. In the present case, CT was useful in the diagnosis of a gastric ulcer because endoscopy was deemed too difficult to perform due to tongue cancer occupying the oral space. Three-dimensional reconstruction of the CT images revealed an ulcerous lesion at the upper posterior wall of the stomach. CT may therefore be helpful for the diagnosis of gastric lesions when usual endoscopy is difficult to perform, as observed in the present patient.
