Outcome and follow-up
After abscess drainage, empiric intravenous piperacillin–tazobactam 4.5g q6h was administered. However, three days later the patient´s condition deteriorated with fever of 39.0°C and CRP increased to 332 mg/l. Piperacillin-tazobactam was continued for a total of 19 days, combined with intravenous ciprofloxacin 400mg q12h for the last ten days. The patient was discharged after 20 days of hospitalization with oral ciprofloxacin 500mg q12h as monotherapy with a treatment regime for a total of eight weeks. The patient fully recovered, and all blood parameters were normal one week after discharge. Seven months after the index admission, the patient was seen in an outpatient setting due a slight discomfort from the upper right abdominal quadrant. The physical examination and all blood parameters were normal. However, a follow-up CT-scan showed slight scarring and small abscess residue at the site of the primary infection. Therefore, a second follow-up CT-scan has been scheduled.
