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