We report a case of somatoparaphrenia in a 41 year-old man after right temporo-parietal stroke. An elaborate system of delusional beliefs was observed concerning the initially paralysed left leg, arm, and hand. The course of these beliefs is analysed as the patient progresses from a full-blown delusional state to having excellent insight into his condition. We outline the types of explanation that seem required to understand how somatoparaphrenic beliefs can arise.
