31. Figure 44–8. Endoscopic ultrasonography (EUS) of gastric tumors. A , The five layers of the gastric wall may be discerned near the bottom of the image, from the 3 o'clock position to the 6 o'clock position ( open arrowhead ). The tumor (TUMOR, solid arrowhead ) involves the fourth hypoechoic (dark) layer, the muscularis propria, but has not encroached on the fifth hypoechoic layer, the serosa. In addition, an enlarged lymph node (LN) at the 6 o'clock position appears to be involved. The patient was found to have a T2N1 tumor. B , A gastric polypoid mass (POLYP, arrowhead ) is pedunculated and involves only the first hyperechoic layer, the superficial mucosa, and has not breached deeper layers, including the muscularis propria (MP). The patient was found to have a benign, 1.5-cm pedunculated hyperplastic polyp. C , The tumor (*) has breached all five layers of the gastric wall, including the fifth hyperechoic (bright) layer and beyond ( arrowhead ). The patient was found to have a T4 tumor. D , Diffuse, hypoechoic infiltrations throughout all five layers of the gastric wall, giving a blotchy moth-eaten appearance ( arrowheads ), and four round, sharply demarcated hypoechoic lymph nodes (LN) are seen. The patient was found to have a stage IIE1 gastric lymphoma. (Courtesy of Markus Goldschmeidt, MD.)
