Gastric web is a rare gastric anomaly and almost all the reported cases have been located in the distal antrum. We experienced a case of neonatal gastric web that was located in the body of stomach, and we report the findings of the upper gastrointestinal series and ultrasonography.

Stomach carcinoma is more common disease in korea than western contries. The reported ultrasonographicfindings of gastric carcinoma were thickening of gastric wall and “pseudokidney” sign. The auther analizedultrasonographic findings of 101 cases with gastric carcinoma who were performed ultrasonography and gastroscopyat Kyung Hee Universtiy Hospital from Oct. 1982 to Oct. 1985. The results were as followings; 1. Types of gastriccarcinoma were consisted with infiltrative type 68 cases, infiltrative type with ulceration 16 cases, polypoidtype with ulceration 1 cases, infiltrative and polypoid type 4 cases, linities plastica type 3 cases, lcerativetype 1 case and polypoid type 1 case. 2. Extent of the lesions were in body and antrum 45 cases, entire stomach 18cases, antrum 18 cases, body 12 cases, body and fundus 6 cases. 3. Ultrasonography was useful in demonstrating theextent of the tumor and the presence of materials elsewhere in abdoment.

Gastric schwannoma is a rare benign intramural tumor arising from the stomach, and it accounts for only 0.1% of all the different kinds of gastric neoplasms, and it's less than 4% of all the benign gastric tumors. This tumor is very difficult to differentiate from the other mesenchymal tumors by the clinical, endoscopic and radiologic findings. In this study, we demonstrate the appearance of this tumor on endoscopic ultrasound and contrast-enhanced abdomen CT. We also show the histopathologic findings of a surgically confirmed gastric schwannoma that was located in the proper muscle layer.

A new method for combining ultrasonography snd endoscopy, endoscopic ultrasonography (EUS), was developed to improve the diagnostic accuracy of ultrasound by direct image of the target lesion via the gastrointestinal lumen. EUS has the unique ability to provide clear sonographic images of the wall structure of the stomach. This capability can be ultilized in assessing the depth of cancer invasion of the stomach by identifying which layer the ultrasonographic change extends to. However, the depressed types of early gastric cancer(EGC) are often accompanied by ulcerative change in the tumor foci. And the ultrasonographic picture is also influenced by the ulcerative change.

PURPOSE: In vitro sonography of lymph nodes was performed to ascertain the differential point between benignancy and malignancy. MATERIALS AND METHODS: Ninty-one lymph nodes were obtained at gastric cancer surgery and pathologically proved as benignancy in 68 and malignancy in 23 cases. Sohographic and pathologic correlation of resected ninty one lymph nodes was done in terms of size, the ratio of longest diameter versus shortest diameter, central hyperechogenicity, and peripheral cortical echo. RESULTS: Sonographic findings of benign lymph node were small size, oval shape(85%), narrow central high echogenicity(44%), and symmetric cortical thickening(41%). Sonographic findings of malignant lymph node were large size, round contour(39%), loss of central high echogenicity(82%), and diffuse increase of cortical thickness(82%). CONCLUSION: The most reliable sonographic criterion for differentiation of benignancy from malignancy was size of a lymphnode.

We encountered a patient with a breast mass which had metastasized from gastric carcinoma representing as aninflammatory carcinoma on ultrasonography. We described the radiologic and clinical features, and review theliterature. The patient had advanced gastric carcinoma and breast ultrasonography demonstrated the presence ofvery ill-defined, infiltrating, and mixed echoic lesions indistinguishable from findings of primary inflammatorybreast carcinoma. Metastatic gastric adenocarcinoma was confirmed pathologically.

We report a case of pancreatic pseudocyst presenting as an intramural gastric tumor on upper gastrointestinal examination, endoscopic ultrasound and computed tomography of the abdomen. Pancreatic pseudocysts in the stomach wall is rare and the most of them presented as a cystic mass, but this case was presented as a gastric mural solid tumor. Exploration revealed an about 4 4 2 cm sized round mass at the midbody of great curvature of stomach, it was in the muscle layer, and removed by surgical operation. The correct diagnosis of this case was established postoperately on the pathologic examination revealed pancreatic pseudocyst.

With recent technical advances, increasing use of sonography in the initial evaluation of patients with abdominal disease may allow the detection of unexpected tumor within the abdominal cavity. Easiness of sonographic detection of bowel pathology, purposely or unexpectedly, warrants the inclusion of bowel loops during ultrasound examination when a patient complains of symptoms indicating diseases of the bowel. In patients complaining of acute abdominal symptoms or nonspecific gastrointestinal symptoms and showing signs such as abdominal pain, diarrhea, hematochezia, change of bowel habit, or bowel obstruction, sonography may reveal the primary causes and may play a definitive role in making a diagnosis. On ultrasonography, abnormal lesions may appear as fungating mass with eccentrically located bowel lumen (pseudokidney sign) or symmetrical or asymmetrical, encircling thickening of the colonic wall (target sign). In patients with mass or wall thickening detected on ultrasonography, additional work-up such as barium study, CT or endoscopy would be occasionally necessary for making a specific diagnosis.

PURPOSE: To evaluate the usefulness of transabdominal ultrasonography as a screening examination in patients with suspicious gastric disease. MATERIALS AND METHODS: We selected 141 patients with epigastric pain and who were found to have antral gastric wall thickening of more than 5 mm in transabdominal ultrasonography, and who underwent gastroscopy immediately following the ultrasonography examination, because we suspected that these patients had gastric disease. We measured the full thickness of the five layers of the gastric wall and evaluated the preservation of this fivelayered structure. We respectively compared the gastric wall thickness and the preservation of gastric layers in 26 normal, 91 gastritis, 12 gastric ulcer, and 12 gastric cancer patients, who were classified based on the gastroscopy results. RESULTS: The mean thicknesses of the gastric wall in the normal, gastritis, gastric ulcer and gastric cancer patients were 5.13+/-0.14 mm, 6.71+/-1.33 mm, 8.08+/-2.80 mm, and 12.45+/-3.70 mm, respectively. The gastric walls in the gastritis, gastric ulcer and gastric cancer patients were significantly thicker than that in the normal patients (p < 0.01). The gastric wall in the gastric cancer patients was significantly thicker than those in the gastritis and gastric ulcer patients (p < 0.01). However, the difference in the gastric wall thickness between the gastritis and gastric ulcer patients was not statistically significant (p >0.01). Except for two patients with gastritis and three patients with gastric ulcer, the stratification of the gastric wall was preserved in all of the normal, gastritis and gastric ulcer patients, whereas it was disrupted in all of the patients with gastric cancer. CONCLUSION: Transabdominal ultrasonography in the fasting state may be a helpful and convenient modality, which can serve as a screening examination in the evaluation of gastric disease. Therefore, careful attention and effort are needed to evaluate the gastric wall during transabdominal ultrasonography.
