A case of 18-year-old girl student with pneumonia to M. pneumoniae was reported.
She was admitted to this hospital in October 1976 with a history of cough, sputum and fever for six days. The chest X-ray revealed a homogeneous infiltration on the right lower lung field.
During the next two weeks she was in a critical condition with dyspnea, cyanosis and remittent fever. On the 23th day the chest X-ray revealed a cavity (1.8×1.6 cm) on the right lower lung field.
The laminagraphy revealed the cavity to be intrapulmonary. The complement fixation titre to Mycoplasma pneumoniae was 1: 1280. Cole agglutination test was 512x. She was treated with E.M. and Betamethasone.
But after two years her X-ray revealed the same cavity yet.
