Pelvic plain radiographic images were suggestive of a deformed left femoral head, narrowed hip space, and osteophyte hyperplasia (Figure 1).
MRI of the hip joint shows a patchy hyperdense focus in the left acetabulum, a small amount of fluid signal shadow in the bilateral acetabulum, and no obvious swelling in the surrounding soft tissues.

Magnetic resonance imaging (MRI) revealed left acetabular bone marrow edema and a small amount of fluid in both hip joints (Figure 2).
Chest radiographs show no obvious substantial lesions in both lungs.

Chest radiograph showed no significant substantial lesions in both lungs (Figure 3).
Lung computed tomography shows multiple pulmonary balloon lesions, and a Staphylococcus aureus infection was considered.

Pulmonary computed tomography revealed multiple pneumonocytocystic changes in the lungs, suggestive of S. aureus infection (Figure 4), and joint puncture and blood culture confirmed the aforementioned suspicion. Considering the patient's condition, we suspected S. aureus bacteremia had spread to various parts of his body, including the lungs (Figure 4) and brain (Figure 5).
Head MRI shows abnormal signals in the left frontal lobe. Combined with the medical history, hemorrhagic infarction caused by bacterial embolism was considered. No obvious abscess cavity is seen, and the hemorrhage is in the subacute stage.
