Aseptic Lymphocyte-Dominated Vasculitis-Associated Lesion as Early as Six Weeks After Total Hip Replacement: A Case Report.

CASE: A 40-year-old man who underwent total hip replacement on the left side with a metal-on-metal (MOM) implant reported swelling at the operative site within 6 weeks of the arthroplasty. Tissue sampled during the revision arthroplasty showed an aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL).

CONCLUSION: ALVAL is a widely recognized complication of MOM hip implants and needs to be considered early, even in completely asymptomatic patients with normal metal ion levels and normal radiographs.
