Senile Lemierre syndrome complicated with descending necrotizing mediastinitis: A case report

Rationale: Senile patients with LS complicated with DNM are rarely seen in clinical practice, and extensive cervical incision and drainage plus administration of effective antibiotics are the basis for treatment. Currently, the treatment controversy mainly has focused on whether mediastinal incision and drainage is necessary for patients with type I DNM, and whether anticoagulation therapy is required for jugular venous emboli and distant metastatic emboli induced by LS.
