2,8-Dihydroxyadenine (DHA) lithiasis is a rare type of urinary stone disease and the deficiency of adenine phosphoribosyltransferase (APRT) activity is known to be the cause of this disease. To identify a 2,8-DHA stone is important because this stone is well managed by medical therapy. Regarding a radiological finding, previous reports have considered 2,8-DHA to be radiolucent like uric acid stone. This report is a case of radiopaque 2,8-DHA stone and proposes that the composition of urinary stones should always be investigated for adequate medical treatment.
