RESUMO
OBJECTIVE: To report on a 6-year-old patient with an infected simple renal cyst. METHODS/RESULTS: A 6-year-old girl was admitted on three occasions for acute infectious syndrome and right lumboabdominal pain. The ultrasound scans showed a simple cyst in the right kidney which contained cellular elements. The patient was treated with antimicrobials on each occasion and the symptoms disappeared a few days later. On her third admission surgery was decided due to the recurrent clinical symptoms, a persistently high erythrocyte sedimentation rate and the presence of intracystic cellular elements, which raised the suspicion of intracystic abscess or tumor. The patient was submitted to surgery; the cyst was drained, resected and the internal wall marsupialized. The postoperative period was unremarkable and the patient is asymptomatic 10 months after surgery. CONCLUSION: The case described herein is uncommon; to our knowledge, a similar case has not been reported in the literature.
