Abstract:
Presentation of 2 cases of retroperitoneal ganglioneuroma (paravertebral and adrenal, respectively), accidentally diagnosed during ultrasound study. In none of these 2 cases diagnosis by thin-needle puncture-aspiration was possible, therefore, surgical exeresis of the lesion was performed. When diagnosis is made prior to surgery, management can be conservative with close follow-up, unless neuroblastoma is identified or there is other disease-derived pathologies present.
