|
|
|
most common location of mucinous cystadenoma of panc
|
tail
|
|
|
management of mucinous cystadenoma
|
should be resected
|
|
|
pathology of mucinous cystadenoma
|
most contain ovarian type stroma
|
|
|
which cystic pancreatic neoplasm can lead to malignancy
|
mucinous cystadenoma
|
|
|
does serous cystadenoma have any malignant potential

no
|
|

|
serous cystadenoma
|
|
|
location of serous cystadenoma
|
usually in pancreatic head
|
|
|
features of serous and mucinous cystadenoma
|
serous: M~W, pancreatic head, +/- central scar, no malig potential, cysts can be small or large
mucinous: W>>>>M, +/- calcs, tail of panc, +malig potential they may be indistinguishable on imaging |
|
|
diffuse cystic replacement of panc
|
VHL
|
|
|
SPN stands for
|
solid pseudopapillary neoplasm
|
|
|
appearance of spn
|
solid and cystic components
+/- calcs |
|
|
main clue to dx SPN
|
will be a pancreatic tumor in a young woman.
|
|
|
enahncement of nml pancreas
|
should be earlier and brighter than the liver
|
|
|
findings a/w VHL
|
CNL and retinal hemangioblastomas
renal cysts, RCC pheo ancreatic cysts serous cystadenomas (panc) panc endo tumors, and adenoCA |
|
|
f/u for 2cm cystic pancreatic lesion incidentally seen
|
f/u MRI in 1 yr
if no growth, done if growth, f/u same as 2-3 cm category |
|
|
f/u for 2-3cm cystic pancreatic lesion incidentally seen
|
MRI/MRCP
if its a serous cystadenoma, f/u q2yrs branch duct IPMN, f/u q6mx2 yrs, then annually uncharacterized, f/u q year |
|
|

|
greater than 4 cm
|
|
|
describe pancreatic divisum
|
no connection btwn main and accessory ducts
most of drainage is via accessory duct/minor papilla |
|
|

|
accessory duct atrophies and drainage is entirely via main duct/major papilla
|
|
|
complications of acute pancreatitis
|
pseudocyst 4-6wks after
hemorrhagic papncreatitis -> risk of panc necrosis panc necrosis pseudoaneurysm abscess |
|
|
what can result from pancreatic necrosis
|
-> duct injury, which if in mid-gland and the tail is not connected to the main duct, pancreatic juices can feed the collection -> surgery to resect pancreas
|
|
|
where do pancreatic mets often go
|
lung
liver |
|
