Objective: To discuss the relationship between obsessive‐compulsive symptoms and a right orbitofrontal lesion. Method: Single case report. Results: A 59‐year‐old man developed obsessive‐compulsive disorder (OCD) symptoms after his head injury. Magnetic resonance imaging brain scans showed a small contusion in the right orbitofrontal region, and single‐photon emission computed tomography revealed hypoperfusion in blood flow at the same region. Conclusion: The OCD symptoms that developed in the present case may be attributable primarily to hypofunction in the lesion localized to the right orbitofrontal area. Although caution is needed for interpretation of the observation because of our experience of only a single case, it suggests that the right orbitofrontal region may be important in forming OCD symptoms.
