: Spectrum of disease," RadioGraphics, vol.
Resection of the porta hepatis
mass and total thyroidectomy were performed with subsequent confirmation of paraganglioma and PTC, respectively.
Four different mechanisms have been described in the literature as causes of obstructive jaundice secondary to hepatobiliary tuberculosis: porta hepatis
TB lymphadenitis causing extrinsic compression of the common bile duct [5, 8, 10-13], head of pancreas involvement mimicking a pseudoneoplasm and obstructive the distal common bile duct [10, 14-18], a retroperitoneal mass caused by TB obstructing the distal bile duct , and a direct involvement of biliary epithelium or pericholangitis resulting in a single or multiple strictures mimicking cholangiocarcinoma [20-22].
Roux-en-Y portoentrostomy was performed for 3 (09.37%) cases of biliary injury at the level of the porta hepatis
The site of the primary colonic resection is assessed for local recurrence, as are the mesentery, coeliac axis and porta hepatis
for metastatic adenopathy.
The liver mass was unresectable due to infiltration to the porta hepatis
. Postoperative pathological result showed highly-differentiated adenocarcinoma of right colon, partial myxoadenocarcinoma, carcinoid of appendix and hepatocellular carcinoma of left liver.
Common hepatic artery was carefully exposed by blunt dissection through retroperitoneal fat and upper margin of the pancreas upto the porta hepatis
, exposing its branches12,13.
Sometimes, there may be large metastatic lymph nodes on the porta hepatis
which may mimic klatskin tumor.
This showed a 1cm pseudoaneurysm of the right hepatic artery in the right lobe close to the Porta Hepatis
. The pseudoaneurysm arose from the anterior branch of the right hepatic artery and communicated with the bile duct.
Imaging revealed a large mass involving the colonic wall and porta hepatis
, probably representing enlarged matted lymph nodes.
