A rare case of pregnancy complicated by mesenteric mass: What does chylous ascites tell us?

Figure 1 Contrast-enhanced axial scan of MDCT revealing a heterogeneous mesenteric huge soft tissue mass, which displaces the SMA.

Figure 2 Coronal MRI image demonstrating a tumor with low to intermediate mixed signal intensity in the lesion's periphery and low signal intensity in the central region of the lesion on T2 weighted images.

Figure 3 Semi-surrounding SMA and SMV (arrow) demonstrated during operation.

Figure 4 Resected small bowel with a well-circumscribed firm mass exhibiting an expanding growth pattern.

Figure 5 Tumoral lesion consisted of spindle cells growing in sweeping fascicles, with eosinophilic cytoplasm and occasional focal infiltration of plump nuclei in pancreas (arrow) (A) and bowel wall (arrow head) (B). Most of the tumor cells showed immunoreactivity for β-catenin (+++).
