Lemierre's syndrome is a rare, life-threatening condition, which may be fatal if not properly treated. This disease refers to thrombophlebitis of the internal jugular vein, which is the result of bacterial sore throat infection (usually in the form of pharyngitis) that extends into the parapharyngeal space. However, it can result from other infective foci in the ear, nose, parotid glands, and paranasal sinuses. The bacteria typically responsible is Fusobacterium necrophorum. Here, we describe a case of Lemierre's syndrome that occurred in a 20-year-old female who presented with neurological deficits following a two-week history of upper respiratory tract infection. Our case displayed typical findings of this rare condition with a review of the previous literature and also to emphasize the importance of high index of suspicion to reduce the mortality of this disease.
