Thoracic Oncology, Mediastinum and Pleura
Evaluate pulmonary, mediastinal and pleural masses, malignant spread and biopsy pathways.
How to prepare for the current Final FRCR Part A
Build general-radiology breadth, then practise integrating clinical context, anatomy, multimodality findings, technique and management to select the single best answer.
Core concepts
Concept 1
Localise a lesion to lung, mediastinal compartment, pleura or chest wall before ranking benign, inflammatory and malignant causes.
Exam cue: Localise the abnormality and identify the organ, compartment, tissue or vessel before naming a diagnosis.
Concept 2
Use contrast CT, PET-CT, MRI and image-guided sampling according to local invasion, nodal or distant disease and tissue requirements.
Exam cue: Use age, clinical setting, tempo and the complete multimodality pattern to rank the most likely explanation.
Concept 3
Describe resectability-relevant imaging features and the safest high-yield target without assigning an exact TNM stage where the linked RCR guidance excludes it.
Exam cue: Select the examination or intervention that changes management while accounting for contrast, radiation, access and urgency.
Concept 4
Apply normal and variant anatomy, modality technique, image quality and relevant imaging science to thoracic oncology, mediastinum and pleura.
Risk pitfalls and guardrails
Equating tracer avidity with malignancy or selecting a necrotic, inaccessible or unnecessarily hazardous biopsy target.
Guardrail: Check justification, contraindications, coagulation or access, dose and complication rescue before selecting the technique.
Do not choose a merely plausible SBA option before comparing every option with the full clinical and imaging context.
Guardrail: Re-read the command word and compare every option; the task is to select the best available answer, not the first plausible one.
Memory anchors
Mediastinal mass: first decision
Localise by compartment and identify organ of origin before using age and tissue characteristics.
Pleural malignancy clues
Nodular circumferential pleural thickening, mediastinal pleural involvement and chest-wall invasion are concerning.
PET-CT limitation
Inflammation can be avid and some indolent or small tumours can be relatively non-avid.
Cancer imaging answer level
Know features that change operability and management; do not assume a specific TNM label is required.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A 66-year-old smoker has a central lung mass. CT shows tumour encasing more than half the circumference of the left main pulmonary artery and obstructing the upper-lobe bronchus. What is the most important next imaging goal?
A 58-year-old woman has an anterior mediastinal mass containing fat, fluid and coarse calcification. What is the most likely diagnosis?
