Gastric malignant lymphoma detected through abdominal ultrasonography during a complete medical check-up: a case report

Abstract

Enlargement of the splenic artery and the hepatoduodenal ligament lymph nodes was detected in a 58-year-old woman during abdominal ultrasonography performed as part of a complete medical check-up conducted at our hospital in December 2017. An ulcerative lesion and mucosal fold thickening in the stomach were observed on gastric radiography examination. Circumferential mucosal fold thickening and an irregular ulcer extending from the angle to the body of the stomach were observed on performing upper gastrointestinal endoscopy. The extension of the gastric wall was adequate. Analysis of the biopsied specimen from the ulcerated region led to the diagnosis of diffuse large B-cell lymphoma (DLBCL), and the patient was referred to a hematology hospital. A thorough examination revealed stage III (Ann Arbor staging) DLBCL. After six cycles of CHOP (combination of cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemotherapy plus rituximab, the patient achieved complete remission. We believe that detailed observation and comprehensive knowledge of abdominal ultrasonography findings along with careful interpretation of the gastric X-ray images were instrumental in achieving an accurate diagnosis in this case.
