TRANSABDOMINAL ULTRASOUND OF GASTRIC TUMOR

Abstract

Ultrasound is often used as a primary procedure in the patient with a nonspecific abdominal complaint. Finding of atypical target pattern or pseudokidney sign anteriorly located in left upper abdomen to mid upper abdomen, adjacent to the visceral surface of left lobe of liver, suggested that the lesion may be originated from stomach. Although differentiation between benign or malignant patterns cannot be definitely made, recognition of ascites, intraabdominal lymphnode, invasion to adjacent structure or evidence of intraabdominal metastasis may be helpful for the indications of malignancy. Four cases of stomach tumor were preliminary diagnosed by ultrasound. The Upper Gastrointestinal study and gastroscopy were performed for definite diagnosis.
