At this time he also started to mutilate his fingers leading to tendon injuries and severe grazing. After detailed discussion with the patient and his family and consideration of his case by an independent Mental Health Review Tribunal he was referred to the Atkinson Morley's Neurosurgical Unit for bilateral limbic leucotomy where considerable experience has been built up over the last twenty years with this procedure.9 While waiting for the opera- tion to be carried out he began to damage his nose and carry out forced Valsalva man- oeuvres leading to extensive petechial http://jnnp.bmj.com/ haemorrhages.
