Q

biliary-enteric fistulas causes & results in

A

causes:

  • chronic cholecystitis
  • duodenal ulcer
  • tumor
  • trauma

results in: Bouveret syndrome, gallstone ileus

22
Q

Rigler triad

A
  • pneumobilia
  • SBO
  • ectopic calcified gallstone (usu in the right iliac fossa)

seen in gallstone ileus

23
Q

adenomyomatosis pathology

A
  • idiopathic, nonneoplastic, noninflammatory GB wall thickening
  • epithelial hyperplasia with mucosal invagination into smooth muscle layer
  • bile or cholesterol crystals deposit in Rokitansky-Aschoff sinuses
  • thickening = focal, segmental, diffuse
24
Q

adenomyomatosis imaging

A

thickening = focal, segmental, diffuse
- segmental form: annular thickening -> strictures (“hourglass” appearance in GB mid body)
US: echogenic foci with comet tail (reverberation of US pulse within cholesterol crystals)
MRI: cystic spaces (=R-A sinuses) with curvilinear arrangement; string of beads

25
GB polyps - types
- cholesterol (>50%) - adenoma (30%): premalignant - inflammatory (10%) - malignant (5%): adenoca (90%), other (mets, SCC, angiosarcoma)
26
GB polyps - management
≤6 mm: no f/u 7-9 mm: yearly f/u w US to ensure no growth ≥10 mm: surgical consultation for cholecystectomy (greater chance of premalignant adenoma) - if no cholecystectomy, annual f/u ACR 2013
27
primary sclerosing cholangitis - imaging
multifocal regions of segmental intra- & extrahepatic biliary ductal dilation and stricturing - active inflammation: abN thickening, hyperenhancement of bile duct walls - clue on MRCP: greater than expected number of peripheral ducts - string of beads, withered tree
28
primary sclerosing cholangitis - complications
cholangiocarcinoma (NOT HCC) biliary cirrhosis: “central regenerative hypertrophy” colorectal carcinoma (if assoc w IBD)
29
recurrent pyogenic cholangitis
formation of pigment stones throughout biliary tree - resultant biliary strictures, repeated bouts of cholangitis - 2/2 Clonorchiasis (liver fluke), Ascaris infxn dilated IHD/EHD full of T1 bright pigmented stones localized IHD dilation MC affects left hepatic lobe
30
Von Meyenberg complexes
benign biliary hamartomas failure of involution of embryonic bile ducts 1-5mm cystic masses, no communic w biliary tree US: echogenic +/- comet tail artifact likely dx if innumerable small, slightly complex "cysts" in healthy pt
31
HIV cholangiopathy
biliary inflam'n caused by AIDS-related opportunistic infxns - CMV, cryptosporidium presumptive diagnosis in advanced AIDS (CD4 <100)
32
HIV cholangiopathy - imaging
multiple intrahepatic strictures (identical to PSC) papillary stenosis GB wall thickening
33
biliary ischemia
complication of hepatic artery stenosis/thrombosis - sole vascular supply to biliary system - assoc w biliary necrosis & abscess formation high mortality rates if retransplantation or thrombectomy/thrombolysis not immediately performed critical to recognize
34
peribiliary cyst
thin walled cysts of serous glands adj to IHD - no communication with biliary tree benign; do not mistaken for dilated bile ducts assoc w chronic liver dz, cirrhosis, ADPCKD
35
hepatic mucinous cystic neoplasm
formerly biliary cystadenoma/carcinoma - now non-invasive or invasive hepatic MCN well-defined uni or multiloculated cystic mass in liver with septations, papillary projections, mural calcifications no communication with biliary tree
36
cholangiocarcinoma - risk factors
primary sclerosing cholangitis recurrent pyogenic cholangitis Clonorchiasis (liver fluke) choledochal cyst
37
cholangiocarcinoma - locations
hilar (Klatskin) - confluence of hepatic ducts intrahepatic/peripheral (least common) - capsular retraction distal (extrahepatic; distal CBD) - “sclerosing”: stricture, ill-defined, desmoplastic - “papillary”: intraductal, polypoid mass
38
emphysematous cholecystitis - demographics
50-70 yo diabetics
39
emphysematous cholecystitis - bugs
Clostridium welchii / perfringens E. coli Bacteroides fragilis
40
Milan criteria liver transplant HCC
One HCC <5 cm or 3 HCC all <3 cm without tumor in vein or evidence of mets elsewhere
41
criteria to use LiRADS
- prior bx proven HCC - cirrhosis - chronic hep B
42
which cystic pancreatic lesions need surgical mgmt
- mucinous cystic neoplasm | - main duct IPMN
43
hemochromatosis patterns
Primary: liver, Pancreas, Myocardium, thyroid Secondary: liver, Spleen, bone marrow
44
cholangiocarcinoma risk in choledochal cyst/caroli disease
< 10%
45
types of castleman's disease
1. unicentric (hyaline vascular --> plasmacytic) 2. HHV8 associated (hypervascular --> plasmacytic) 2. HHV8 -ve/idiopathic (" ")
46

rejection
51
