I am sorry to see this report.
She is only 68 years young and seems to have major problem.
is not that common at her age , but can occur.
From the description of CT findings, she may have primary cancer
of the gallbladder which is causing blockage of the main channel
that carries the bile from the liver
to the gallbladder and also
portion of the channel inside the liver .Bile from the gallbladder
is usually released into the duodenum
. There seems to be a mass
effect with pressure on the duodenum and also the part of the colon
that is close to the liver.
It is very difficult to say whether this is operable without additional
studies which might include, endoscopy
, ERCP, MRCP, CT-guided biopsy
She needs to be seen by a top specialist , may be at a university hospital
setting where all these are available.
I wish her well.
