Cavum septum pellucidum (CSP) is a morphological alteration of the septum pellucidum that should disappear at 3-6 months of age. CSPs that persist for longer, and non-communicating CSP, are classified as a neurodevelopmental disorders and have been associated with schizophrenia and other psychotic disorders, especially in cases with large CSPs. Prevalence rates vary according to the measurement method, and the figures range from 0,1% to 85% in the general population and from 15% to 44,8% in schizophrenia. A series of clinical features such as cognitive disorders, more negative symptoms and verbal learning and sentence comprehension disorders has been found in patients with psychotic disorders and large CSP. We present the clinical case of a 19-year old patient diagnosed with hebephrenic schizophrenia in which a CT scan revealed a giant CSP (2,6 cm) and who presented significant negative symptoms, cognitive deterioration, verbal learning and sentence comprehension disorders and important behavioural disorders.
