Presentation
Abdominal pain.
Patient Data
The hepatic attenuation value is less than that of the spleen, suggesting fatty liver disease.
A 59× 47 mm isodense mass is present at the caudate lobe of the liver. After contrast media injection, the mass shows inhomogeneous enhancement more than surrounding parenchyma on all phases, without washed out.
The gallbladder is not seen at the anatomical location due to prior resection.
There is a 59x 47 mm mass at the caudate lobe of the liver, which is a low signal on T1WI and slightly hypersignal on T2WI. After contrast injection, the mass shows arterial dominant phases hyperenhancement and is iso intense on delayed phases.
The gallbladder is not seen (prior surgery). CBD shows mild dilatation, which could be related to post-cholecystectomy changes.
A 6mm cortical cyst is seen in the left kidney.
Case Discussion
The enhancement pattern of liver mass is compatible with benign hypovascular lesions, and hepatic adenoma is the most likely diagnosis.
