Abstract
in English, German

A 40-year-old woman was referred to our department for further investigation of a renal mass identified at an ultrasound (US) examination carried out in a private clinic because of abdominal pain. The mass was oval and hypoechoic, measured about 20 mm in diameter and was located near the left renal sinus; color Doppler showed peripheral blood flow. US examination carried out in our department using different equipment confirmed the presence of the mass but revealed intralesional blood flow suggesting aneurysm. This diagnosis was confirmed at subsequent computed tomography (CT) scanning and magnetic resonance imaging (MRI). The patient refused to undergo surgery and she is currently being monitored and has suffered no sequelae.

Una donna di 40 anni giungeva alla nostra osservazione per la rivalutazione di una formazione renale identificata ad un esame ecografico effettuato esternamente per dolore addominale. Tale formazione, ovalare ipoecogena di circa 20 mm, era localizzata a livello del seno renale di sinistra e mostrava al color Doppler segnale vascolare perifericamente. Il controllo ecografico da noi eseguito con apparecchiatura più performante confermava la presenza della formazione evidenziando tuttavia segnale vascolare al suo interno e ponendo il sospetto di aneurisma, confermato poi ai successivi esami TC ed RM. La paziente rifiutava di sottoporsi ad intervento chirurgico terapeutico ed è tuttora in follow-up senza sequele.
