Obsessive-compulsive disorder (OCD) is a common anxiety disorder which can be chronic and sustained. An OCD suferer experiences intrusive and repetitive thoughts, impulses, and behaviors, which ultimately cause extreme discomfort. We report a case of a patient that primarily presented with lower urinary tract symptoms who was subsequently treated with antibiotics. Nonetheless, the symptoms persisted. In subsequent consultations, the patient clarifed the compulsive nature of his symptoms and was treated as a case of OCD. Terefore, it is crucial for physicians to correctly identify the nature of the symptoms to manage the disorder properly and to avoid unnecessary consultation and treatment. To the best of our knowledge, this is the frst report of other presentations of OCD.
