Abstract
Isolated gastric varices (IGV) (resulting from varying etiologies) were diagnosed in six patients using ultrasound examination of the wall of the fluid-filled stomach. Small gastric varices are seen as circular or linear anechoic channels within the gastric wall without a significant intraluminal projection. Large varices are seen as anechoic, lobulated "bulging masses" projecting into the fluid-filled lumen of the stomach. Doppler technique assists in confirming the vascular nature of these lesions and thus avoids confusion with other hypoanechoic lesions of the gastric wall. The technique is simple, noninvasive, and extremely useful in diagnosing IGV in patients investigated for recurrent undiagnosed gastrointestinal bleeding.
