A case of malignant fibrous histiocytoma (MFH) of the gastrocolic ligament
is presented. It appeared as a huge, thin walled cystic tumour in the upper
abdominal cavity on CT. Barium studies showed splaying of the stomach and
transverse colon by the mass. 1 year after resection of the cystic tumour,
recurrence occurred at the greater curvature of the stomach and in the live
r, with a cystic appearance similar to the primary tumour. To our knowledge
, the CT appearance of primary cystic MFH of the gastrocolic ligament has n
ot been previously documented.
