MORENO RUIZ, Nelson Leandro. Differential diagnosis of pulmonary mass: round pneumonia. rev.fac.med. [online]. 2011, vol.59, n.1, pp.42-45. ISSN 0120-0011.

The presence of a round lesion in radiography of the thorax should always lead to neoplasia being suspected; however, round pneumonia should be taken into account in differential diagnosis. It is an unusual form of pneumonia which is presented in adults, only being seen in 1% of cases, and may be associated, or not, with symptoms of acute infection and can only be accurately diagnosed by radiological and not by clinical evolution. The case of a patient having symptoms of acute infection and a round radiological lesion is presented. The patient received antibiotic treatment leading to improvement of the clinical picture, but without radiological changes leading to a pulmonary biopsy being made
