Lesson 2.1 P4 Flashcards
Characteristics of benign Polypoid masses (4)
more common
may be multiple
<10mm
don’t change in size when followed up
Characteristics of abnormal polypoid masses (5)
>10mm singular >60 years old gallstone disease rapid change in size when followed
What are we trying to Rule out when looking at biliary tree (4)
stones
infections
neoplasms
extrinsic compression
choledochal cysts are ______ disease
congenial
type 1, 2 and 3 of choledochal cysts are
cystic dilation of CBD
type 4 of choledochal cysts involves
intrahepatic ducts as well as CBD dialation
type 5 of choledochal cysts is called
carolis disease
is type 5 a true choledochal cysts
no
choledochal cysts are most commonly seen on what populations
east Asia
carolis disease involves
intrahepatic biliary tree
carols disease associated with
medullary sponge kidneys
does carolis disease affect men or women more
equal
Complications of carolis disease
biliary stasis cholangitis stones and sepsis hepatic fibrosis portal hypertension
what happens with primary choledocholithiasis
stones form within ducts related to disease causing dilation of bile ducts -> resulting in stasis
causes of primary choledocholithiasis (4)
sclerosing cholangitis
carolis disease
parasitic infections of liver
sickle cell anemia
what happens in secondary choledocholithasis
migration of stones from the GB into the CBD
symptom of secondary choledocholithasis
RUQ/epigastric pain
sonographic signs of secondary choledocholithiasis (4)
dilated CBD proximal to stone
intrahepatic ducts might be dilated
GB distension
large stones have shadow
where will the majority of stones be
in the distal CBD at the ampulla of rater
differential diagnosis to CBD stones (3)
papillary tumor
blood clot
biliary sludge
how to we tell stones apart from differential diagnosis
only stones shadow
how do we see smaller stones on US (2)
proximal dilated ducts help to delineate them
harmonic imaging improves the contrast resolution
Mirizzi sindrome is a clinical syndrome of (3)
painful jaundice
fever
obstruction of CHD
mitizzi syndrome is the result of
stones eroding into the CHD and resulting in a fistula
what is a fistula
an abnormal connection between an organ, vessel, intestine or other structure
