wk 8 9 Imaging Flashcards
4 causes of epigastric pain
MI
peptic ulcer
acute cholecystitis
perforated oesophagus
RUQ pain could be 7
acute cholecystitis duodenal ulcer congestive hepatomegaly Hepatitis pyelonephritis (renal disease) appendicitis Pneumonia
LUQ could be 6
ruptured spleen gastric ulcer aortic aneurysm perforated colon pyelonephritis (renal disease) pneumonia
aortic aneurysm could be
LUQ
LLQ
early appendicitis pain would be
LLQ
pain from UC most likely
LLQ
MEckels diverticulitis would be associated with pain in
RLQ
presentation of cholecystitis
cholecystitis - cystic duct - gallstones
RUQ pain
exacerbated by eating
+/- weird LFTs
first line for suspected cholecystitis
US
followed up by MRCP / ERCP
presentation of pancreatitis
epigastric/diffuse ab pain
high serum amylase
causes of acute pancreatitis
Idiopathic Gallstones (common) Ethanol (most likely) Trauma Steroids Mumps Autoimmune Scorpion bite Hyperlipidemia/triglyceridemia ERCP Drugs
define pseudocyst
thin walled structure/cavity of epithelium, indicative of pancreatitis
first line investigation for suspected perforation
erect CXR
followed by CT
describe pain of appendicitis
central ab pain
later localised in RIF
may be referred pain to left side (rosvings sign)
appendicitis in female patient, what else should be considered
gynaecological pathology
first line for appendicitis
US
diverticulitis is classicly
LIF
lower ab pain
t/f diarrhoea and PR bleeding associated with diverticulitis
true
would expect elevated inflam markers
vascular causes of abdominal pain would most likely be ____ onset and associated with ____ pain and _____
sudden onset
associated back pain and hypotension
patient presents with distended abdomen, if bowel source is suspected what is the first line investigation
AXR
distended abdomen due to fluid, what is the first line investigation
US
CT scan to investigate acute haematemesis, which contract oral or IV would be used
IV
+/- angiography and intervention
protocol for lower GI bleed
same as upper
CT +/- angiography and intervention
dysphagia investigated by
endoscopy
when would a change in bowel habit lead to a PR exam
presence of ab pain, anaemia, weight loss
radiological investigations of a change in bowel habit would be
barium enema CT colonography (better)
small bowel disease suspected, what type of investigation
fluoroscopic contrast study
will show if stricutre/wall thickening/ fistulation
known small bowel crohns/ large bowel with small bowel crohns would be investigated usiing q
MRI
what type of scann can localise active inflammation
radio-labelled white cell scan
associated symptoms of jaundice
weight loss
ab pain
ascites
itch
if jaundiced what is the first line iinvestigation
US
good at determining intra/extra biliary tree dilation, less reliable at cause - MRCP +/- ERCP next step
