empyema
Very LowTechnical/Medical
Definition
Meaning
A collection of pus in a body cavity, especially the pleural cavity surrounding the lungs.
In medical terminology, it refers specifically to a purulent (pus-containing) infection that has accumulated within a pre-existing anatomical space, most commonly used for pleural empyema (in the chest) but can also apply to other sites like joints (septic arthritis) or the gallbladder.
Linguistics
Semantic Notes
The term is almost exclusively used in medical contexts. It denotes a specific pathological condition, not just any infection. It implies the presence of a confined space filled with pus, distinguishing it from a simple abscess (which is a walled-off collection) or diffuse infection.

Examples
By Part of Speech
verb
British English
- The infection may empyematise, requiring urgent intervention. (Very rare derivative)
American English
- The cavity can become empyematous. (Adjectival form more common)
adjective
British English
- The patient presented with empyematous pleural fluid.
American English

Examples
By CEFR Level
- A severe pneumonia can sometimes lead to a complication called empyema.
- The surgeon had to operate to drain the empyema from the patient's chest.
- Thoracentesis revealed turbid, purulent fluid, confirming the diagnosis of a parapneumonic empyema.
- Video-assisted thoracoscopic surgery (VATS) is often the preferred approach for decortication in cases of organized, chronic empyema.
Learning
Memory Aids
Mnemonic
Think: 'EMP' (like an employee) + 'YEMA' sounds like 'ema' in 'ema-nation of pus'. An EMP is stuck in the chest (YEMA) with pus.
Conceptual Metaphor
The body cavity as a container (the pleural space) that becomes filled with a harmful substance (pus).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'абсцесс' (abscess), which is a walled-off pus collection in tissue. 'Эмпиема' is the correct, direct equivalent.
- Avoid literal breakdown like 'em' + 'pyema'; it's a single medical term.
Common Mistakes
- Misspelling as 'empyemia' (confusion with '-emia' meaning blood condition).
- Using it to describe any chest infection rather than a specific pus-filled cavity.
- Incorrect plural: 'empyemas' is standard, though rare.

FAQ
Frequently Asked Questions
No. An abscess is a collection of pus within newly formed tissue (a walled-off cavity). An empyema is pus within a pre-existing anatomical space, like the pleural cavity.
Yes, though less common. Terms like 'gallbladder empyema' or 'joint empyema' (septic arthritis) are used, but 'pleural empyema' is the default meaning.
Treatment typically involves antibiotics to fight the infection and drainage of the pus, often using a chest tube or surgical procedures like VATS (video-assisted thoracoscopic surgery).
It comes from the Greek 'empyēma', meaning 'abscess' or 'purulent matter', from 'empyein' (to suppurate), from 'en-' (in) + 'pyon' (pus).
