A 63-year-old otherwise healthy woman presented with a 2-month history of right-upper quadrant and epigastric abdominal pain. She denied experiencing nausea, vomiting, fever, or weight loss. Physical examination revealed a discrete intra-abdominal mass that was elastic and freely mobile in all directions. Laboratory findings were unremarkable. Surgical history was positive for appendectomy and hysterectomy.
Ultrasound and magnetic resonance imaging of the abdomen revealed a cystic lesion in the right hypochondrium, close to the duodenum and the gastric antrum, with a thick and irregular wall and thin septa inside the cyst (Figure 1).
Magnetic resonance images revealed an inhomogeneous, well-delineated mass with a size of 6 × 6 cm, which was hypointense on T1-weighed spin echo images and intensely hyperintense on T2-weighted spin echo images.
