A large heterogeneous right upper quadrant soft tissue mass lesion is seen insinuated between the gastric antrum/duodenum and the gallbladder and appears inseparable from the gallbladder. It shows a heterogeneous appearance with internal hyperdense areas on the non-contrast images denoting hemorrhage and heterogenous post-contrast enhancement. The gallbladder is infiltrated and is also distended by internal similar soft-tissue masses. The mass compresses the gastric antrum and duodenum.

Surrounding multiple mesenteric lymph nodes are noted.
