Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 23 Non-Hodgkin lymphoma of the stomach. A: Coronal T2-weighted single shot fast spin echo (SSFSE) and (B) axial fat-suppressed T2-weighted SSFSE images. There is marked, diffuse, asymmetric gastric wall thickening with smooth outlines, predominantly involving the gastric body and antrum, associated with mildly increased heterogeneous T2 signal intensity (arrowheads, A and B), large conglomerate nodal mass at the gastrohepatic ligament (long arrow, A), and multiple enlarged retroperitoneal lymph nodes (short arrows A and B). Constellation of findings is diagnostic of non-Hodgkin gastric lymphoma with diffuse abdominal lymphadenopathy.
