Neuropsychiatric symptoms and diagnosis of grey matter heterotopia : A case - based reflection

A 39-year-old, unemployed Caucasian male was arrested for assault with intent to cause grievous bodily harm involving an incident of extreme violence which occurred in a psychiatric ward where he was being treated as an involuntary mental health care user under the Mental Health Care Act No. 17 of 2002.1 Because of his history of treatment for mental illness, he was sent for psychiatric observation in terms of Sections 77, 78 and 79 of the Criminal Procedures Act No. 51 of 1977, as amended.2 The observation was done at Weskoppies Hospital, a tertiary psychiatric hospital in Pretoria, South Africa. During this period of evaluation, he was diagnosed with an interesting underlying condition of grey matter heterotopia (GMH), which had previously been misdiagnosed as tuberous sclerosis (TS).
