Cavernous Gastric Hemangioma as an Unusual Cause of Upper Gastrointestinal Bleeding in a Young Woman.

Case Rep Gastroenterol 2022 Jan-Apr;16(1):1-7. Epub 2022 Jan 10.

Division of Hepatology and Gastroenterology, Department of Internal Medicine, Shin Kong Wu Ho-Su Memorial Hospital, Taipei, Taiwan.

Gastric hemangiomas (GHs) are extremely rare vascular lesions of mesodermal origin that may occur in isolation or in conjunction with underlying congenital pathology. Due to the scarcity of these tumors, there is no standardized diagnostic method; however, many have found the combination of endoscopic investigation and radiographic imaging to be most effective, with the presence of phleboliths on computerized tomography as being pathognomonic for GHs. Surgical treatment for symptomatic lesions is curative with no reports of recurrence. Read More

World J Gastroenterol 2021 Nov;27(41):7125-7133

Department of Diagnostic Imaging, University of Texas MD Anderson Cancer Center, Houston, TX 77030, United States.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal (GI) tract and are thought to arise from precursors of the interstitial cells of Cajal. GISTs can arise anywhere in the GI tract, but most commonly originate from the stomach and small intestine. The majority of GISTs occur as a result of activating mutations in two receptor protein tyrosine kinases: KIT and/or platelet-derived growth factor receptor-α. Read More

ACR Appropriateness Criteria® Epigastric Pain.

J Am Coll Radiol 2021 11;18(11S):S330-S339

Specialty Chair; and Director, CT and MRI, and Section Chief, Abdominal Imaging, Virginia Commonwealth University Medical Center, Richmond, Virginia.

Epigastric pain can have multiple etiologies including myocardial infarction, pancreatitis, acute aortic syndromes, gastroesophageal reflux disease, esophagitis, peptic ulcer disease, gastritis, duodenal ulcer disease, gastric cancer, and hiatal hernia. This document focuses on the scenarios in which epigastric pain is accompanied by symptoms such as heartburn, regurgitation, dysphagia, nausea, vomiting, and hematemesis, which raise suspicion for gastroesophageal reflux disease, esophagitis, peptic ulcer disease, gastritis, duodenal ulcer disease, gastric cancer, or hiatal hernia. Although endoscopy may be the test of choice for diagnosing these entities, patients may present with nonspecific or overlapping symptoms, necessitating the use of imaging prior to or instead of endoscopy.
