The chest X ray in Q-fever: a report on 69 cases from the 1989 West Midlands outbreak.
Acute and serial chest radiographic appearances of Q-fever in a large UK outbreak in the West Midlands are described. In 69 acute films (taken within 20 days of onset of illness), 10% of films were normal. Appearances in 62 abnormal films were varied and, in contrast to some previous reports, showed no features that might distinguish Q-fever pneumonia from pneumonias of other origins. Analysis of serial films in 47 cases showed that complete radiographic resolution frequently took up to 6 months, longer than has been described previously. Initial appearances deteriorated over the first 2 weeks of radiographic surveillance in 20% of cases. No relationship was found between the extent of radiographic change and the age of the patient or the presence or absence of respiratory symptoms. Age did not affect time to resolution.
