A 68-year-old female had positive blood cultures for MSSA and a paraspinal abscess, which was subsequently drained, and a TEE displayed a large vegetation on the right atrial junction. She was initially treated with oxacillin 2 g every 4 h from days 5 to 12. Negative blood cultures were obtained on day 9. On discharge (day 13), ceftriaxone 2 g every 24 h was initiated for completion of 6 weeks of therapy from first negative blood culture. Follow-up computed tomography (CT) scans showed that the paraspinal abscess resolved.
A 19-year-old male admitted for possible meningitis presented with numbness and fever and developed acute paraplegia secondary to a spinal abscess. Surgical and blood cultures revealed MSSA on day 1, then the patient developed sepsis secondary to a pulmonary septic embolus. Vancomycin was discontinued, and oxacillin 2 g every 4 h was initiated on day 4. He had negative blood cultures on day 6. On day 14, he was discharged to rehabilitation on ceftriaxone 2 g every 24 h for 8 weeks.
