Diagnosis:
Cholangiocarcinoma
MR Technique:
3.0 T scanner (Siemens Verio) using a Body Flex coil anteriorly and a Spine coil posteriorly. Images 1: axial T2 HASTE (TR/TE 1400/93 ms, scan time 1 min 15 sec, slice thickness 5 mm); Image 2: axial VIBE before contrast administration (TR/TE 3.9/1.3 ms, scan time 11.8 sec); Images 3-4: axial VIBE performed 20, 40, and 60 seconds (respectively) after intravenous administration of 0.1 mmol/kg gadolinium chelate (TR/TE 3.0/1.3 ms, scan time 11.8 sec); image 6: axial VIBE performed at 8 minute delay (TR/TE 4/1.5 ms, scan time 14.1 sec).
Imaging Findings:
MThere is an ill-defined large liver mass occuying most of the left liver lobe which is hypointense on T1 (Image 2) and slightly hyperintense on T2 (Image 1). After contrast administration, sequential images (images 3-5) illustrate initial peripheral enhancement with progressive filling after 8 minutes (image 6).
