[Aspergillar prosthetic hip infection with false aneurysm of the common femoral artery and cup migration into the pelvis].

We report a case of Aspergillus fumigatus infection of a total hip arthroplasty. This rare infection was demonstrated at surgical revision of a loosened prosthesis with migration of the cup into the pelvis associated with a false aneurysm of the femoral artery. A vascular time was required before the orthopedic revision. This case illustrates the importance of the preoperative work-up in the event of cup migration. The double approach was required in our patient to control and repair the vascular structures. The difficult treatment of Aspergillus fumigatus is also discussed.
