Results
IMT was proven in 14 (42%) patients and CC in 19 patients (57%).
Clinical finding:
IMT patients often present with fever (n=5,
35%), abdominal pain (n=6,
42%) and blood tests showed often elevated infection parameters ( 57%).
Patients with CC often present with painless jaundice (n=9,
47%) and with elevated liver enzyme in the bloodtests ( 79%).
On imaging,
there is no obvious difference in lesion density or SI between IMT and CC.
Both entities show increasing enhancement during delayed phase.
