Fatal Massive Pulmonary Embolism Following a Minor Ankle Injury as a Rare Cause of Sudden Unexpected Death: A Case Report

Abstract

Venous thromboembolism is a condition that includes both deep vein thrombosis and pulmonary thromboembolism. Pulmonary thromboembolism is a condition that is familiar to forensic pathologists for its common cause of sudden unexpected death. Fatal pulmonary thromboembolism following deep vein thrombosis has been previously reported as a consequence of major ankle injury but not following minor ankle injury. Here, I report the case of sudden unexpected death in a 54-year-old female without known underlying risk factors for venous thromboembolism, except for a history of minor injury at her left ankle, which possibly caused local vascular wall damage with subsequent deep vein thrombosis and eventual massive pulmonary thromboembolism.
