We present the case of a 24-year-old woman who presented to the emergency department with mid-epigastric pain and nausea. Contrast enhanced dual-energy CT showed high iodine signal in the small bowel lumen concerning for gastrointestinal bleeding since oral contrast was not given. However, overt bleeding symptoms were absent. Further in-house analysis of the dual-energy CT data revealed the hyperattenuating intraluminal material to be oral indigestion medicine containing magnesium, aluminum, or bismuth, and not extravasated iodine.

Hyperattenuating contents detected in the gastrointestinal (GI) tract on CT scans are commonly seen and are almost always due to the purposeful ingestion of an oral contrast agent, usually barium- or iodine-based, used for evaluating the GI tract. Occasionally, other ingested material such as antacids or other medications, foreign objects, and medical devices can also be hyperattenuating. While these are usually correctly identified, these materials can potentially be misdiagnosed as a pathologic condition.

Gallbladder pathology is common in dogs, but published studies describing the computed tomographic (CT) appearance of many gallbladder pathologies are currently lacking. This retrospective, multicenter, cases series, descriptive study evaluated the CT features of confirmed gallbladder pathology in 34 dogs. In this subset of dogs, the most common pathologies included cystic mucosal hyperplasia (15/34, 44.

Purpose: To assess the diagnostic performance of computed tomographic (CT) angiography as the initial diagnostic examination for patients presenting to the emergency room with acute lower intestinal bleeding.
Materials And Methods: The study was reviewed and approved by the ethics committee, and written informed consent was obtained from each patient or their closest relative when the clinical condition precluded consent by the patient. This prospective study comprised 47 patients (27 men, 20 women; mean age, 68 years) with acute lower gastrointestinal tract bleeding who were referred to undergo emergency colonoscopy for evaluation.

Objective: The purpose of this study was to evaluate retrospectively the CT findings and clinicopathologic features of gastrointestinal metastasis from lung cancer.
Conclusion: The most common histologic type of lung cancer among the patients in this study was squamous cell carcinoma (n = 12). The most common clinical presentation was abdominal pain (n = 15).
