Abstract
Retroperitonal teratomas are rare. We report on a case of a retroperitoneal secondary localisation of a gonadal teratoma in a patient who had developed primary testicular teratoma 12 years previously. The retroperitoneal mass was detected with an abdominal CT requested for the management of a non-specific abdominal pain. CT and MRI examinations showed cystic retroperitoneal masses combined with calcifications and peripheral enhancement. Review of the literature is presented, including the common differential diagnoses to be considered.
Highlights
Retroperitoneal teratomas are uncommon in the adult population: primary retroperitoneal teratomas represent 1 to 11% of the retroperitoneal neoplasms [1]
A retroperitoneal mixed mass was detected with CT
Detailed anamnesis revealed a previous testis teratoma 12 years previously, converting the initially primary retroperitoneal mass as a high suspicion of secondary location of the initial teratoma, which was confirmed by surgery
