Pleurisy vs Pulmonary Embolism

Clinical comparison — shared symptoms, key differences, distinguishing diagnostic tests, treatment pathways, and when to seek urgent evaluation.

Condition Overview

Condition A

Pleurisy

Pleurisy is inflammation of the pleural membranes surrounding the lungs, causing sharp chest pain that worsens when breathing deeply or coughing.

Condition B

Pulmonary embolism is a life-threatening blockage of the pulmonary arteries, usually by clots from deep vein thrombosis. Sudden shortness of breath, chest pain, and rapid heart rate are classic presentations requiring emergency treatment.

Shared Symptoms — Why They're Confused

Both conditions present with 3 overlapping symptoms, making clinical differentiation essential.

chest pain shortness of breath cough

Key Clinical Differences

Pleurisy

Sharp pleuritic chest pain worsening on inspiration
Usually follows viral URI or autoimmune disease
Pleural friction rub on auscultation
No haemodynamic compromise

Pulmonary Embolism

Pleuritic chest pain with dyspnoea and tachycardia
Associated DVT symptoms (leg swelling, tenderness)
May cause haemoptysis
Right heart strain on ECG (S1Q3T3)

Distinguishing Diagnostic Tests

Test	Pleurisy	Pulmonary Embolism
D-dimer	Normal or mildly elevated (non-specific inflammation)	Significantly elevated — high sensitivity for PE
CT-PA	Normal pulmonary vasculature; pleural thickening or effusion	Filling defects in pulmonary arteries
ECG	Normal or sinus tachycardia only	S1Q3T3 pattern, right bundle branch block, sinus tachycardia

Treatment Approaches

Pleurisy

•NSAIDs or colchicine for viral pleurisy
•Treat underlying cause (autoimmune, bacterial)

Pulmonary Embolism

•Anticoagulation (DOAC or LMWH)
•IVC filter if anticoagulation contraindicated

When Doctors Consider Each Diagnosis

🔵 Consider Pleurisy when:

→Pleuritic pain after URTI, autoimmune history, normal D-dimer

🟢 Consider Pulmonary Embolism when:

→Dyspnoea disproportionate to pain, DVT risk factors, elevated D-dimer
