Fatal pyothorax: a rare complication of retropharyngeal abscess.

Fatal pyothorax following a massive acute retropharyngeal abscess in an adult is reported. Acute non-tuberculous retropharyngeal abscess usually develops following a penetrating injury due to a foreign body or endoscopy. Microbial isolates are mixed and consists of aerobic and anaerobic organisms. It may lead on to mediastinitis since there is a potential communication between the two spaces. Immediate cervical, pleural and mediastinal surgical drainage along with appropriate antibiotics can be life saving.
