SBAs for the 2A Unit 1 Flashcards
Loss of upper left heart border, preserved descending aorta outline
Lingula lesion
Uncomplicated sequestration on PET
cold
Scarring (lung) on PET
hot
Ground glass and reticular change post lung transplant
Drug toxicity
Aortic coarctation rib norching
3-9th ribs, affects sides with coarcted supply
Commonest location for atrial myxoma
Left atrium
Commonest thoracic manifestation of RA
Pleural effusion
Mediastinal enlargement in TB
Suggests primary TB
Septal thickening in TB
Suggests reactivation TB
Contrast injection site prior to IVC filter placement
Left common iliac vein, to assess for persistent left SVC
Acute extrinsic allergic alveolitis likeliest appearance
Diffuse airspace shadowing
Primaries causing cavitatory lung mets
SCC
Malignant melanoma,
Sarcoma,
Colonic carcinoma
Commonest radiographic abnormality on CXR in SLE
Pleural effusion
Prognostic indicator in CTPA
RV/LV diameter ratio
BAC usual location
Peripheral, usually subpleural
Pancoast tumour histological type
SCC (likeliest)
Oesophageal vs bronchogenic cyst
Oesophageal have thicker wall
Loss of right heart border
Right middle lobe collapse
Atrial myxoma on MRI
Hypointense to myocardium on T1, variable T2 and enhancement
Commonest CT feature of mycotic aneurysms
Perianeurysmal soft tissue mass
Contralateral shift of trachea post pneumonectomy
Suggests bronchupleural fistula
Coughing up grape-skin like material
Hydatid lung disease, calcification is rare
Myocarditis MRI findings
Epicardial patchy enhancement
Lesion obscuring the descending aorta on CXR - location
Posterior mediastinum
Progressive massive fibrosis on PET
Hot
Sarcoid lymphadenopathy
Usually spares posterior mediastinum, unlike NHL
LAM
Thin walled air containing cysts. Not cavitating
Post lung transplant acute changes, timeline
Within 1 day: hyperacute rejection
1-4 days: reperfusion oedema
1-2 weeks: acute rejection
Left atrial enlargement features
Straightening of left heart border.
Double atrial shadow on right.
Elevation of left main bronchus.
Splaying of the Carina.
Displacement of descending aorta to left.
Pulmonary fibrosis and lower lobe bronchiectasis
Sjogren syndrome
Flow of contrast towards porta hepatis during TIPSS
Suggests puncture of biliary tree
TIPSS normal shunt gradient
<12mmHg
Eisenmenger syndrome CXR features
Paucity of pulmonary vasculature,
Enlarged central pulmonary artery
RV hypertrophy.
Linear calcification of main pulmonary arteries
