A pus-filled cavity inside lung parenchyma is called what?

• A. Abscess
• B. Cavity
• C. Pneumatocoele
• D. Granuloma

Answer: (A)

A localized pus-filled cavity within the lung tissue is an abscess. It forms when an infection causes destruction of lung parenchyma and liquefactive necrosis, leading to accumulation of pus that creates a distinct cavity. The wall of an abscess is produced by surrounding inflammatory tissue, and imaging often shows an air-fluid level where air from the bronchial tree communicates with the purulent center. This differs from a general cavity, which is any air-filled space within a lesion and isn’t necessarily filled with pus. A pneumatocoele is an air-filled, thin-walled space without pus, typically seen after certain pneumonias in children. A granuloma is a nodular lesion of organized inflammatory tissue, not pus-filled. So the pus-filled cavity inside lung parenchyma is an abscess.
