Figure 1. Imaging of a patient with periodontitis who developed cerebral sinus thrombosis and pulmonary embolism. (A) Gadolinium-enhanced T1-weighted magnetic resonance image reveals filling defect in the left transverse sinus, indicating thrombus formation within the dural sinus. (B) Magnetic resonance venogram shows absence of flow signal in the left transverse and sigmoid sinuses and internal jugular vein. (C) Chest computed tomography shows multiple pulmonary nodules with cavitation, which is compatible with septic emboli.
