case_images: Enhanced CT scan of the abdomen axial (A, B) and coronal (C, D) images demonstrate an enhancing mass in the region of the porta hepatis (black arrow) with biliary duct dilatation (red arrow).

case_images: The mass was obstructing the proximal common hepatic duct resulting in dilatation of the intrahepatic biliary tree (Figure 1).
case_images: Axial (A, B) and coronal (C) T2-weighted images show a hyperintense mass in the region of the porta hepatis (blue arrow) with a dilated biliary ducts (red arrow). The mass (blue arrow) is hypointense in T1-weighted images (D).

case_images: The mass was T2 hyperintense and T1 hypointense and showed moderate enhancement on postcontrast sequence with severe diffuse restriction (Figures 2 and 3).
case_images: MRI of the liver axial diffusion-weighted (A, B) demonstrates a hyperintense mass in the region of the porta hepatis (red arrow) with a several hyperintense foci (green arrows). Axial postcontrast images (C, D) show heterogonous enhancement of porta hepatis mass (blue arrows).

case_images: fig3
case_images: The mass was T2 hyperintense and T1 hypointense and showed moderate enhancement on postcontrast sequence with severe diffuse restriction (Figures 2 and 3). In addition, the MRI revealed multiple foci of restriction scattered throughout the liver and some of them showed subtle enhancement on postcontrast sequence suggestive of liver microabscess (Figure 3).Constellation of MRI findings was suggestive of localized TB of the porta hepatis; however, neoplastic lesion such as rhabdomyosarcoma and lymphoma could not be excluded and further evaluation with a tissue biopsy was advised.
