All of the following are true regarding Lung abscess, EXCEPT
Abscess > 2 cm in size require excision
If ruptures into pleura simple drainage is sufficient
Most common cause is secondary to upper respiratory tract infection
Surgery is not usually part of the treatment
(A) Abscess > 2 cm in size require excision # LUNG ABSCESS:> Abscesses in the lung do not occur unless the underlying infection has caused thrombosis of the segmental artery and vein leading to infection with tissue necrosis.> The most common causes are secondary to a chronic upper respiratory tract infection (sinusitis, dental abscess) or following bronchial obstruction from a neoplasm.> Treatment:> Most acute abscess resolve with appropriate antibiotic therapy and postural drainage.> The course of antibiotics is usually the highest permitted dose for a prolonged period.> The virulent organism may change with such a prolonged antibiotic assault and the sputum must therefore be regularly monitored.> Surgery is not usually part of the treatment.> It is better for a lung abscess to drain via the bronchus and the contents are coughed up.> Inserting a percutaneous drain creates a particularly difficult form of bronchopleural fistula.
