Endoscopic ultrasonography (radial scanning). A: Disruption of the second layer with preservation of the other layers and no nodal involvement (T1 N0); B: Diffuse infiltrative pattern: diffuse trans-mural involvement of the gastric wall with irregular layer border and not uniform echogenicity. Diffuse circumferential tickening of the second, third and fourth layers; the is still preserved (T2 N0); C: Localized hypoechoic alteration limited at the third layer, whit a mild thickening of the stomach wall and circumscribed to a small portion of the gastric circumference (T1 sm N0); D: Persistent tickening of the first and second layer in a patient affected by diffuse large B cell lymphoma in complete remission after the immuno-chemotherapy performed 2 years before.
