Hemoptysis. Is it caused by Pasteurella multocida infection or congenital pulmonary artery anomalies?

INTRODUCTION: infection is the second most frequent localization and usually manifests as pneumonia. Unilateral absence of pulmonary artery (UAPA) is a very rare congenital anomaly. Adult patients with UAPA are usually asymptomatic or their symptoms are nonspecific. CASE REPORT: in sputum. The organism was also isolated from nasopharyngeal swab of her dog. During hospitalization, she was also diagnosed with UAPA and chronic obstructive pulmonary disease (COPD). DISCUSSION: infection while it is common in cases of UAPA due to existing developed collateral circulation especially in older patients. CONCLUSIONS: infection and not UAPA which was more likely to be the case.
