 The patient is a 39-year-old woman with polymyositis/dermatomyositis on methotrexate once a week.  The patient has also been on high-dose prednisone for an urticarial rash.  The patient was admitted because of persistent high fevers without a clear-cut source of infection.  She had been having temperatures of up to 103 for 8-10 days.  She had been seen at Alta View Emergency Department a week prior to admission.  A workup there including chest x-ray, blood cultures, and a transthoracic echocardiogram had all remained nondiagnostic, and were normal.  Her chest x-ray on that occasion was normal.  After the patient was seen in the office on August 10, she persisted with high fevers and was admitted on August 11 to Cottonwood Hospital.  Studies done at Cottonwood:  CT scan of the chest, abdomen, and pelvis.  Results:  CT chest showed mild bibasilar pleural-based interstitial changes.  These were localized to mid and lower lung zones.  The process was not diffuse.  There was no ground glass change.  CT abdomen and pelvis was normal.  Infectious disease consultation was obtained.  Dr. XYZ saw the patient.  He ordered serologies for CMV including a CMV blood PCR.  Next serologies for EBV
