OBJECTIVES: Aneurysmatic processes of the renal artery after transplant are rare entities, generally secondary to technical defects or infectious pictures. Among other presentations, dissecting aneurysm are exceptional, having a particularly difficult diagnosis due to the lack of specific clinical data which could differentiate them from other processes such as graft rejection or acute tubular necrosis, as well as the absence of characteristic representative images. METHODS: We report one case of dissecting aneurysm after a kidney transplant resulting in graft loss. RESULTS: We analyze the presentation form, diagnostic procedures, pathologic studies, and possible therapeutic options. CONCLUSIONS: Dissecting aneurysm of the renal artery is a rare entity of difficult diagnosis due to the poorness of presenting symptoms and the difficulty of finding it in routine tests, being necessary to think of it and to perform angiography as the only diagnostic test. Treatment is carried out by hilar reconstruction or transplant nephrectomy when the former is not possible.
