Primary Isolated extraluminal Hydatid Cyst of Left Pulmonary Artery
Mimicking COVID-19 Infection
Abstract
Hydatid cyst of pulmonary artery is extremely rare. There were few
reports of intramural involvement of pulmonary artery secondary to
cardiac or lung hydatic cyst in literature. To the best of our knowledge
there was no report of primary isolated extraluminal hydatid cyst of
left pulmonary artery. A twenty-eight–year-old female presented to the
hospital with complaint of progressive dyspnea. The patients had no
common COVID-19 infection symptoms. The RT-PCR for COVID-19 RNA was
negative. Spiral chest CT-scan demonstrated a cystic mass sized 83×34 in
middle mediastinum. Intraoperatively, the intrapericardial mass arising
from left pulmonary artery and extended to the hilum of left atrium. The
mass was resected and pathology report noted a hydatid cyst. The
postoperative course was uneventful and the patient was discharged with
administration of albendazol for 3 months. However hydatid cyst primary
isolated extraluminal hydatid cyst of pulmonary artery are extremely
rare, in cases with pulmonary artery stenos or hypertension
manifestation should be considered as a probable differential diagnoses.
Regarding to ongoing COVID-19 pandemic the present case misdiagnosed
with coronavirus infection.
