Sonography of the Gastro-Intestinal Tract can reveal intra-mural tumours, Intra-mural hematoma, Lesions of Ampulla of Voter like benign and infiltrating mass lesions. Neoplastic lesion is usually a segment involvement, and shows irregularly thickened, hypo echoic and peristaltic wall with loss of normal layering pattern. It is usually a solitary stricture and has eccentric irregular luminal narrowing. It shows loss of normal Gut Signature. Enlargement of the involved segment seen Shouldering effect at the ends of stricture is most common feature. Enlarged lymphnodes around may be seen. Primary arising from wall itself and secondary are invasion from peri-Ampullary malignancy or distant metastasis. All these cases are compared and proved with gold standards like surgery and endoscopy. Some extra efforts taken during all routine or emergent ultrasonography examinations can be an effective non-invasive method to diagnose primarily hitherto unsuspected benign and malignant Gastro-Intestinal Tract lesions, so should be the investigation of choice.
