Presentación atípica de absceso retroperitoneal secundario a apendicitis aguda evolucionada / Atypical presentation of a retroperitoneal abscess secondary to a developed acute appendicitis

Secondary retroperitonitis after a developed acute appendicitis (without intraperitoneal involvement) is an unusually event. But otherwise manifested as inguinal tumoration, in a patient without previous inguinal hernia, is still less frequent. The fact that the retroperitoneal abscess founded the disection of the structures of the inguinal canal (without previous hermiation) by the retroperitoneal abscess simulating the clincal presentation of a strangulated inguinal hernia, supported to perform this presentation.
