Figure 1 Septic pulmonary embolism. A, Contrast-enhanced CT scan of the chest in a 20-year-old male patient revealed bilateral pleural effusion with cavitating nodules (B, white arrow). In addition, a small intramuscular collection was seen in paraspinal muscles on the patient’s right side (A, black arrow). Also note a small hypodense filling defect in azygous vein suggestive of thrombosis (A, white arrow). Based on these findings, a diagnosis of septic pulmonary embolism was made. Intramuscular abscesses were thought to be the primary source of infection. Blood culture and pus culture from the abscess was positive for methicillin-resistant Staphylococcus aureus.
