We report a case of Aspergillus arthritis of the shoulder in a renal transplant recipient. Cultures of three joint fluid specimens grew Aspergillus fumigatus. Itraconazole as sole treatment resulted in initial clinical and roentgenographic improvements but failed to prevent deterioration in joint function. A relapse with fatal neurologic involvement occurred. Immune deficiency-inducing risk factors for aspergillosis include neutropenia and corticosteroid therapy. Previously published cases of Aspergillus arthritis of limb joints are reviewed. The advantages and limitations of itraconazole as single drug therapy are outlined.
