Masterpass Chest 3 Flashcards
Correct size selection for aortic stent
approx 10% greater than native aortic diameter to ensure seal
Hibernating vs infarcted myocardium (MRI)
No delayed enhancement vs delayed hyperenhancement
Adult presenting with enlarged heart and pulmonary plethora
Suggests left to right shunt, at this age ASD
Neonate with cardiomegaly and reduced pulmonary blood flow
Pulmonary stenosis
Cardiac resync pacemaker lead location
Right atrial appendage, right ventricle, left ventricle (cardiac vein)
Syphilitic aneurysm
Saccular aneurysm of ascending aorta with thin, dystrophic wall calcification
Bleeding disorder associated with pulmonary AVM
HHT (Osler-Weber-Rendu)
Normal myocardial peak enhancement
20-30 seconds
Commonest site for intracardiac thrombus
Left atrial appendage
Reduced uptake inferiorly, similar in rest and stress images
Artefact from high rising diaphragm, especially if overweight
Involvement of which extra-nodal site of Hodgkin’s lymphoma causes worst prognosis
Small bowel
Casoni skin test diagnoses
Hydatid disease
Commonest location of hydatid disease in lungs
Right lower lobe
Intralobar vs extralobar sequestration venous drainage
Pulmonary vs systemic
Commonest location for lung rheumatoid nodules
Peripheral
Commonest cause of round pneumonia
Strep pneumoniae
Smoker, thin walled cysts and centrilobular nodules with normal intervening lung
LCH
Causes of calcified lung mets
Testis, breast, colon (mucinous adenocarcinoma), osteosarcoma, ovarian
Most sus form of calcification in lung nodule
Multiple small foci
Legionairre’s disease rarely causes
Lymphadenopathy
Lower zone emphysema in young pt
Alpha-1 antitrypsin deficiency
Hyaline membrane formation on histology
Acute Interstitial Pneumonitis
Diffuse pulmonary haemorrhage on CT
Multifocal consolidation and ground glass change
Indications for lower limb thrombolysis
Acute or acute on chronic ischaemia, graft thrombosis, thrombosed popliteal aneurysm, periprocedural thrombolysis
Type II endoleak Rx
Follow-up, likely to be self limiting
Enlarged right heart border, with prominent anteriosuperior aspect
Right atrial enlargement
Commonest cause of neonatal cyanosis
Transposition
Commonest location of tracheal diverticulum
At the level of thoracic inlet, on the right posteriolateral wall
Optimal window setting for pulmonary embolus
Width 700, Level 100
