PREVIOUS CASE: PANCREAS
A 55-year-old woman underwent abdominal ultrasonography for evaluation of possible gallstones. Cholelithiasis could not be demonstrated, but there was a 7.5 cm multiloculated cyst involving the distal pancreas. Subsequent distal pancreatectomy revealed a multiloculated cyst (7.5 x 7.0 x 6.0 cm) filled with cloudy, amber-colored, thin fluid. The cyst wall ranged from 1mm to 3.0 mm in thickness.
