A Giant Duodenal Leiomyoma Showing Increased Uptake on 18F-Fluorodeoxyglucose Positron Emission Tomography

Figure 1

Abdominal MRI and abdominal contrast-enhanced CT. Abdominal MRI shows a homogeneous and well-demarcated 74 × 98 × 122 mm mass at the cranial part of the uterus (arrow), with a low signal intensity on T1-weighted image (a) and mostly low signal intensity and partially high intensity on T2-weighted image (b) (arrowhead). Abdominal contrast-enhanced CT shows a well-demarcated oval mass with a smooth margin and enhancement in the pelvis (black arrow). The enhanced arteries in the tumor are detected (black arrowhead). The tumor is supplied by the superior mesenteric artery (white arrow), and the surrounding lymph nodes are enlarged (white arrowhead) (c, d).
