Presentation
Pancreatic head large lesion on the US
Patient Data
A well-defined, large, hypodense mass with a thin pedicle originating from segment III of the liver's left lobe. The mass presents with a pattern of peripheral, nodular puddling, and centripetal enhancement that fills in partially on the delayed images. The lesion is adjacent to the neck of the pancreas.
There are also 3 lesions in segments IV, VI, and VII with lacunar enhancement patterns.
Case Discussion
This is a case of a large pedunculated hepatic hemangioma originating in segment III.
On the US, the mass mimics a large pancreatic head lesion, but on contrast-enhanced CT, specific nodular puddling enhancement of a pedunculated hepatic hemangioma is seen.
Complications of pedunculated hemangioma include torsion and infarction, producing mostly abdominal pain.
