Lemierre's syndrome is also known as the forgotten disease, and is a rare but life-threatening complication that can arise after surgical extractions of infected mandibular third molars. Owing to its rarity, oral and maxillofacial surgeons might not immediately recognise or can underestimate the pathological signs, and consequently do not apply the appropriate therapy to treat the syndrome. Here, we report on the occurrence and management of a case of Lemierre's syndrome, where the complications affected the right sigmoid sinus. Since the condition appear to be underreported and not properly highlighted, eventual systematic review and meta-analysis of the occurrence of the Lemierre's syndrome are highly recommended.
