a: A chest X-ray showed infiltration in middle and lower lesions of both lungs on admission. b: Chest CT images showed low attenuation area (LAA) throughout in upper lobe and small thin-walled cavities surrounded by GGO on admission.

A chest X-ray showed infiltration in middle lesions of both lungs (Fig. 1a). A chest CT scan showed low attenuation area (LAA) throughout in upper lobe and small thin-walled cavities surrounded by GGO (Fig. 1b).
The course of the hospitalized. High dose methylprednisolone (500 mg/day) was administrated on day 11-13, and gradual decrease after day 14. After treatment, HHV-6 DNA decreased but CMV-antigen increased on day 26. PSL: predonisolone, mPSL: methylprednisolone, AZM:azithromycin, MEPM: meropenem, MCFG: micafungin, VRCZ: voriconazole, GCV: ganciclovir, HHV-6: Human herpes virus 6, CMV: cytomegalovirus.

High dose methylprednisolone (500 mg/day) was administrated on day 11-13. However, multiple cavities rapidly emerged predominantly in the upper and middle lobes on day 12 (Fig. 3a and b), when positive conversion of GM test was identified.
Chest CT images showed multiple nodules without cavities one year after discharge from the hospital.
