Imaging findings
Following a recent tooth extraction, a patient rapidly developed an extensive cervical soft tissue infection that descended into the upper mediastinum, demonstrating features of severe descending mediastinitis with widespread inflammatory changes.
Key takeaways
Descending mediastinitis is a life-threatening complication of head and neck infections, such as those originating from dental extractions. Infection rapidly spreads along fascial planes from the neck into the mediastinum. Typical causative organisms are polymicrobial, including Streptococci and Prevotella denticola, emphasizing the need for broad-spectrum antibiotic therapy and aggressive surgical management.
