title: Infected simple renal cyst. Case report.
abstract: OBJECTIVE
  To present a new case of an infected simple renal cyst, its diagnosis and the treatment carried out.
  
  
  METHODS
  30 year-old female patient admitted to the Internal Medicine ward suffering a prolonged fever syndrome. On physical examination she presented tachycardia and pain in the left hypochondrium on deep palpation. Abdominal ultrasound revealed the existence of a great size left renal cyst with a highly echogenic content; this liquid hyperdensity was confirmed by simple and i.v. contrast CT scan.
  
  
  RESULTS
  Cyst punction was performed through a lumbar via, getting approximately 400 millilitres of a clear and odourless yellow liquid; then it was sclerosed with ethanol. The microbiological study of the extracted liquid was negative. The patient's clinical evolution has been satisfactory and renal ultrasound controls were normal.
  
  
  CONCLUSIONS
  Faced with a simple infected renal cyst whose location allows percutaneous lumbar approach, punction with synchronic sclerosis plus parenteral antibiotic therapy with ciprofloxacin is the recommended treatment.
