Case report: Be alert to parvovirus infection in patients with unexplained anemia after cerebral hemorrhage surgery

This case underscores the potential severity of PVB19 infection following cerebral hemorrhage surgery, particularly when accompanied by unexplained anemia. Accurate diagnosis requires a high index of suspicion and the use of advanced diagnostic tools. Management primarily involves IVIG therapy and supportive care. This case highlights the importance of expanding the differential diagnosis in postoperative patients presenting with unexplained anemia and multi-organ dysfunction, as early recognition of atypical infections may improve clinical outcomes.
