Thrombophlebitis is a known complication of head and neck infection, which can result in propagation of infected thrombi and associated complications. While antegrade/downstream propagation of thrombus is well described-the Lemierre syndrome-thrombophlebitis can spread in atypical patterns which has specific diagnostic and treatment considerations. In this series, we highlight 6 cases of atypical thrombophlebitis patterns complicating head and neck infection, 5 of which extend intracranially. Through these pathways, head and neck infections such as oral cavity, oropharynx, or skin can be the culprit of remote, including intracranial, complications, which may be overlooked. Furthermore, understanding pathways of venous drainage and communication can help accurately diagnose thrombophlebitis patterns and associated complications.

01:30Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
01:30Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
