Fig. 6.
Perivascular epithelioid cell neoplasm (PEComa) in a 53-year-old woman. (A) Photograph shows gross appearance of the small (1.4 cm × 0.9 cm × 0.5 cm) encapsulated pancreatic tumor. (B) Axial post-contrast fat-suppressed gradient-echo T1-W sequence shows homogeneously hypointense rounded lesion of the pancreatic body (arrow), exhibiting no contrast enhancement. (C) On axial T2-WI, the lesion (arrow) appears hyperintense compared to skeletal muscle. (D) DWI in the axial plane (b = 600 s/mm2) shows diffusion restriction of the lesion (arrow).
