Non-thrombotic Pulmonary Embolism Due to Liver Hydatic Cyst: A Case Report

Abstract

Background: A non-thrombotic pulmonary embolism is defined as embolization to the pulmonary circulation. It may be caused by microorganisms, foreign bodies, different cell types or gas in the pulmonary circulation. Pulmonary hydatid cyst-induced embolization is a rare complication of heart or liver hydatid cysts. Case Report: We describe the fatal case of a 15-year-old boy without any known prior illness who was admitted to the hospital after feeling unwell and dropping to the ground while playing ball. During the autopsy, a lesional mass, with dimensions of 13x6 cm, was observed in the left lobe of the liver. The histomorphological examination of pulmonary sections showed scolices observed in pulmonary vessel lumina, thus a non-thrombosis hydatid embolism was diagnosed. Based on the findings, the cause of death was recorded as a non-thrombotic hydatid embolism. Conclusion: The present case is interesting because a non-thrombotic pulmonary embolism rarely results in sudden death, and a definitive diagnosis was possible only by a histopathological examinatio
