Pulmonary aspergilloma and pulmonary actinomycosis are rare pulmonary infectious diseases. Clinical manifestations of pulmonary aspergilloma and pulmonary actinomycosis include chronic cough, fever, chest pain, haemoptysis and other pathologies, but some patients may be asymptomatic. We report a case of a healthy 33-year-old woman without any underlying diseases, who was admitted to Zhongxing Branch of Taipei City Hospital, Taiwan, for intermittent haemoptysis and right upper chest pain, which had persisted for several months. A chest radiograph revealed a focal consolidation in the right upper lobe (RUL) of the lung, which grew in size over time. A sputum study and bronchoscopy revealed no positive findings, although malignancy could not be ruled out. Thus, the patient received a wedge resection of the RUL lesion. Subsequent, pathological examination demonstrated the presence of pulmonary aspergilloma and pulmonary actinomycosis. The patient's symptoms resolved after resection of the RUL lesion.
