“…Reports on objective methods of evaluating echogenicity in gastrointestinal diseases are sparse [10]. Kajiyama et al [18] advocated the method by comparing tumor echogenicity with that of adjacent organs such as the liver and spleen.…”

“…Endoscopic ultrasonography (EUS) has been reported to be an effective modality in the assessment of gastrointestinal neoplasms, enabling us to evaluate the extension and depth of tumor invasion, original layer of submucosal tumor (SMT), homogeneity of internal parenchymal echo, and echogenicity of lesions [1,2,3,4,5,6,7,8,9,10,11,12,13]. Because echogenicity reflects histopathological structure, its evaluation is important to the differential diagnoses of neoplastic lesions.…”

A Classification System of Echogenicity for Gastrointestinal Neoplasms

Background and Aims: To confirm the utility of a newly-devised endoscopic ultrasonography (EUS) echogenicity classification system, which is based on the normal five-layer structure of the gastrointestinal wall, for the differential diagnosis of gastrointestinal neoplasms. Methods: A total of 275 patients with gastrointestinal disease detected by endoscopy, 53 with submucosal tumor (22 esophageal, 27 gastric, and 4 duodenal), 208 with cancer (58 esophageal, 150 gastric), and 14 with gastric malignant lymphoma, were examined. In each case, we performed standard EUS with 7.5, 12, or 20 MHz to evaluate the echogenicity of the lesion. Echogenicity was classified into seven levels that is based on the echogenicity of the normal five-layer structure of the gastrointestinal wall. The levels are stratified from anechoic (level 0) to hyperechoic (level 6), muscularis propria and deep mucosa being referred to as level 2 and level 4, respectively. Level 6 was equivalent to or higher than the echogenicity of submucosa. Results: EUS findings revealed several distinct echogenicities among the diseases. In submucosal tumor, levels 0, 2, and 6 were observed only in patients with cyst, myogenic tumor, and lipoma, respectively. In malignancies, levels 0, 5, and 6 were not observed in this study. The echo level of malignant lymphoma was markedly lower than that of epithelial cancer. Conclusion: Our classification system of echogenicity can be a useful method in the differential diagnosis of gastrointestinal neoplasms.

“…Fatty replacement of pancreas may be uniform or may be unevenly distributed, and Langerhans are usually not affected by fatty replacement (4). No etiology has been established for fat replacement of the pancreas; however, several predisposing factors have been suggested: age, obesity, diabetes mellitus, chronic pancreatitis, hepatic disease, dietary deficiency, viral infection, steroid therapy, obstruction of the pancreatic duct, and fibrocystic disease (7,8). Experimental and clinical studies have shown that fat replacement of the pancreas does result from ligation of the pancreatic duct or obstruction of the pancreatic duct by a tumor or a calculus.…”

Perilesional Steatosis in Ectopic Pancreas Mimicking Exogastric Mass : A Case Report

We report an unusual case of ectopic pancreas that appeared on radiologic images as a lobulated, submucosal mass enclosed by fat component in the gastric lower body. Although, ectopic pancreas including fat component is extremely rare, in the setting of gastric submucosal mass with containing perilesional fat, these findings should be considered in ectopic pancreas as part of the differential diagnosis.

Gastric glomus tumor: A hypervascular submucosal tumor on power doppler endosonography

Gastric glomus tumors are rare submucosal lesions that typically occur in the fourth endosonographic layer. We describe a 69-year-old patient who presented with intermittent epigastric pain and in whom a submucosal tumor was encountered during upper gastrointestinal endoscopy. Endosonography revealed a heterogeneous, hypoechoic fourth-layer tumor. Power Doppler imaging revealed prominent intratumoral vascular signals demonstrating its hypervascular nature. A diagnosis of glomus tumor was made via histopathologic evaluation of the resected tumor.
