Imaging SBA Module 3 Flashcards
Haemochromatosis - pancreatic signal intensity
Primary - can still be normal in non-cirrhotic liver
Commonest site of oesophageal rupture
Left lateral, lower third
Cirrhosis - portal vein doppler
Hepatofugal flow in an enlarged portal vein
Pseudomembranous colitis
Bowel wall thickening with relative lack of stranding
Important rectal Ca staging
T3 - extension beyond the muscular wall into perirectal fat.
t3a<1mm, t3b1-5mm, t3c 5-15mm, t3d >15mm
N1 = 1-3 sus nodes. N2 = >3 sus nodes
Commonest finding in gastric MALT
Ulcers of varying sizes, depth and number
Active hepatic haemorrhage on CT
Focal, high attenuation linear irregular areas of attenuation (100-300HU)
Percentage of L sided rib injuries associated with underlying splenic injury
20%
Indications for TIPS
Variceal haemorrhage resistant to medical or endoscopic therapy,
Refactory ascites,\
Hepatorenal syndrome
Budd chairi syndrome
Contraindication to TIPS
Portal vein thrombosis
Massive splenomegaly DDx
Myelofibrosis,
Malaria,
Gaucher,
Lymphoma,
Kala-azar,
CML
Whipple’s disease
Migratory arthralgia,
Diarrhoea, malabsorption, weight loss, fever
CT: Pleural and pericardial effusions, sacroilitis, bulky low density lymphadenopathy, bowel mucosal thickening
Oesopageal Ca imaging pre-resection
18F-FDG PET CT
Does not use IV contrast media
Hepatic AML association with TS
Only 6%
Metallic artefact in MRCP
Can cause signal voids as artefact, leading to pseudo-filling defects
Commonest complication of liver transplant
Hepatic artery thrombosis
Causes of calcified liver mets
Usually mucinous tumours
- Colon, breast, stomach, ovary
Also melanoma, thyroid, chondrosarcoma, carcinoid, leiomyosarcoma, neuroblastoma
Bouveret syndrome
Gastric outlet obstruction due to gallstone in distal stomach or proximal duodenum.
