Imaging SBA Module 1 Flashcards
Rebound thymic hyperplasia vs recurrent lymphoma
Chemical shift MRI.
Thymic hyperplasia demonstrated reduced signal in out of phase, in keeping with fat
Pericardial effusion on CXR
Globular heart
Vascular access for endovascular treatment - considerations
Don’t want access site too close to target site
Mediastinal mass - localising on CXR
Hilar vessels visible - not middle mediastinum.
Paraspinal lines obliteration suggests posterior mediastinum
Chest amyloid
Multiple tracheal and pulmonary nodules.
Multifocal irregular tracheal narrowing.
Recurrent infections
Arterial graft thrombosis Rx
Recombinant TPA 15mg bolus + 2ml/hr
Bronchiolitis obliterans
Risk factors - connective tissue disease and transplant.
Imaging: patchy groundglass and centrilobular nodules.
Bilateral, subpleural and lower zone dominant.
Also bronchiectasis
Contrast volume and rate for coeliac axis angiography
30ml @ 5ml/s
Pulmonary LCH findings
Centrilobular, poorly defined, peribronchiolar micronodules sparing lung bases with normal intervening lung and lung volumes
Aortic sinuses of valsalva - location
2cm above the coronary vessels
Cardiac resynchronisation devices - CXR
Leads sit in right atrium, apex at right ventricle and coronary sinus over left ventricle
Rx for type 1 endoleak
Angiographic coil deployment or glue sac embolisation
Hodgkin lymphoma staging system
Ann Arbor:
1 - discrete area of lymphadenopathy
2 - more than one area of lymphadenopathy on same 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
Pacemaker wire descending left of the heart
Persistent left SVC
Chronic/subacute lung symptoms which resolve on admission
Hypersensitivity pneumonitis
Bicuspid aortic valve
Cardiomegaly, systolic murmum, widened superior mediastinum.
Valve may calcify
Fibroid passage
Commonest complication post uterine fibroid embolisation.
Pain, infection, bleeding.
Most common in fibroids in contact with endometrial surface
Radiation induced tumour
aka Radiation Induced Lung Disease.
Classically a distinct line between normal lung and abnormal (fibrosis, consolidation, collapse) corresponding to the radiation field
T staging of lung cancer
T1 <3cm
T2 3-7cm
T3 >7cm
T4 - multiple ipsilateral lobes or mediastinal or carinal involvement
Round atelectasis
Adults (pneumonia is kids).
Round mass with volume loss and pulling bronchovascular bundle towards the lesion
Bronchial carcinoid tumour
No gender prediliction, tend to affect younger adults.
No invasion, no lymph nodes, solitary.
Histology: sheets of glands with calcification and amyloid deposition
Active intercostal bleeding on CT - next step
Immediate cardiothoracic referral
Common patterns of pulmonary drug toxicity
Diffuse Alveolar disease
NSIP
COP
Eosinophilic pneumonia
Pulmonary haemorrhage
NOT UIP
