Pulmonary septic emboli
 Discussion of Pulmonary septic emboli
- Septic emboli are seen most commonly in:
- Patients with infective endocarditis
- Patients with infected venous catheters or pacemaker leads
- Patients with periodontal disease
 Imaging Findings for Pulmonary septic emboli
- The CT appearance of septic emboli includes nodules and wedge-shaped subpleural opacities with or without cavitation and the feeding vessel sign.
- The feeding vessel sign consists of a distinct vessel leading directly into the center of a nodule. This sign has been considered highly suggestive of septic embolism, the prevalence varying from 67-100% in various series (note: the feeding vessel sign also occurs in pulmonary metastasis).
