A 24-year-old male with PMH of testicular cancer and recent chemotherapy was admitted from an OSH with fever and given cefepime. On day 2, blood and sputum cultures became positive for MSSA, and cefepime was de-escalated to oxacillin 2 g every 4 h. A chest CT displayed cavitary lesions determined to be caused by MSSA. It was suspected that the MSSA BSI was due to septic emboli from a central line infection, and his chemotherapy port was removed. On day 8, oxacillin was discontinued, and he was initiated on ceftriaxone 2 g every 24 h. He was discharged on day 10 to complete 4 weeks of therapy. Nine days after discharge, he was readmitted with progressive shortness of breath, fever, chills, and night sweats. A pleural fluid culture yielded MSSA, so he received ceftriaxone on days 1–4 and oxacillin on days 4–7. He was discharged on ceftriaxone therapy to complete the 4 weeks.
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.
