Fig. 1A. 36-year-old woman who presented with abdominal pain. Axial
T1-weighted (TR/TE, 600/14) (A) and axial T2-weighted (5000/112)
(B) spin-echo MR images show well-defined unilocular cystic lesion
(arrows) in pancreatic head. Note that apparent interfaces seen in
cystic lesion and gallbladder are artifactual.
