Imaging SBAs unit 1 Flashcards
Obese pt, large epicardial fat pad on CXR
Mediastinal Lipomatosis
Recurrent lymphoma vs Thymic hyperplasia
In/out of phase MRI. Thymic hyperplasia will demonstrate fat
Important consideration for angioplasty site of access
Needs sufficient distance between puncture site and target
Hilum overlay sign
Hilar vessels still visible through mediastinal mass, proving mass is not in middle mediastinum
Aplastic anaemia most commonly caused by
Thymoma
Pericardial calcifications often caused by
Constrictive pericarditis
Pulmonary nodule follow up <8mm
High risk –> PET
Low risk –> CT 1 year
Post procedure thrombosis of arterial graft, Rx
Recombinant tissue plasminogen activator, 15mg bolus + 2mg/hr infusion
Fluoro appearance of successful canalisation of portal vein in TIPS
Contrast flows via large vessels to liver periphery
Bilateral, subpleural and lower zone patchy ground glass and centrilobular nodules.
Associated with connective tissue disorders and transplant
Bronchiolitis Obliterans
General tips for injection rates/volumes for angiography
Larger vessels need higher rates and volumes of contrast.
Distal lower limb needs more volume but somewhat limited rate due to pain
Centrilobular, poorly defined peribronchiolar nodules, sparing the bases. Normal intervening lung
Langerhans Cell Histiocytosis
Aortic sinuses of valsalva - location
2cm above the coronary vessels
Widened upper mediastinum, high density material adjacent to aorta with preserved fat plane between them
Ligamentum arteriosum (developmental remnant)
IR wire - Cobra
Reverse facing curve, good for general use and visceral angiography
Sidewinder wire
Shepherd’s crook, good for visceral angiography
Benson
Angulated tip, good for arch vessel cannulation
SOS Omni
Reverse facing curve, good for renal artery angiography
Marfans pt, 1cm pneumothorax, Rx
Cardiothoracic team referral (May need bullectomy)
Osteosarcoma, ?mets. Next Ix
Bone scan, followed by CT chest for staging
Tuberous sclerosis vs LAM
Tuberous sclerosis has lower zone fibrosis
Endoleak types
Type 1: leak at graft attachment site
Type 2: Sac filling from branch vessel
Type 3: leak through defect in graft
Type 4: Leak through graft fabric porosity
Type 5: Expansion of sac without demonstrable leak
Type 1 endoleak Rx
Coil or glue embolisation (angiographically)
Hodgkin Lymphoma staging
Ann Arbor
1: discrete area of lymphadenopathy
2: More than one area on one side of diaphragm
3: Lymphadenopathy on both sides of diaphragm
3E: Adenopathy above diaphragm with extralymphatic involvement
3S: Adenopathy above diaphragm with splenic involvement
4: Adenopathy on both sides of diaphragm with extralymphatic spread
Dyspnoea, responsive to steroids.
Mosaic attenuation in middle zones with focal basal opacities
Hypersensitivity pneumonitis
Previous radiotherapy. Fibrosis with an area of focal consolidation
Radiation induced tumour
Lung tumour T staging
T3: 2 tumours in same lobe
T4: Tumours in different lobes
M1: Tumours in different lungs
Minimal common iliac artery diameter for EVAR
8mm
Commonest interstitial lung disease picture in RA
NSIP
Round pneumonia vs round atelectasis
Round pneumonia occurs in kids
Round atelectasis occurs with asbestos
Lupus pernio
Purple rash on ears and cheeks, associated with sarcoid
Histology: Gland like sheets with calcification and amyloid deposition
Carcinoid
Cavitating lung mass with spontaneous pneumothorax in young person
Osteosarcoma met
Young, pulmonary and hepatic nodules, liver failure
Sarcoid
Smoker, widespread ground glass and early fibrosis sparing upper lobes
Desquamative interstitial pneumonia
Trauma, rib fractures, extravasation from intercostal vessel, Rx
IR embolisation
Contraindication to uterine fibroid embolisation
Current use of GnRH, causes the uterine artery to become too small to catheterise. Wait 3 months without them
Pt with central line, diaphragmatic elevation, cause
Phrenic nerve palsy, associated with central line insertion
