The Case Challenge series includes difficult-to-diagnose conditions, some of which are not frequently encountered by most clinicians but are nonetheless important to accurately recognize. Test your diagnostic and treatment skills using the following patient scenario and corresponding questions. If you have a case that you would like to suggest for a future Case Challenge, please contact us.
A 71-year-old man in generally good health begins to notice urinary problems. He gets up twice each night to urinate (nocturia), has a slow urinary stream, and has a sense of incomplete emptying. He denies urinary burning (dysuria) or blood in the urine (hematuria). Otherwise, he has no known medical conditions and takes no medication. Two years prior, he had an insurance examination, at which time his prostate-specific antigen (PSA) test result was 1.5 ng/mL.
