Conclusion:
The pulmonary artery involvement by hydatid cyst was limited to case reports. In this case we reported a primary isolated extraluminal hydatid cyst arising from pulmonary artery with progressive dyspnea due to compression of cyst on pulmonary artery. Regarding the pandemic and symptoms that mimicked COVID-19, the patient was misdiagnosed as COVID-19 infection. However extraluminal hydatid cyst of pulmonary artery is extremely rare, it should be considered as a probable differential diagnoses in similar cases.
