Morphological differences among cavum septi pellucidi obtained in patients with schizophrenia and healthy individuals: forensic implications. A post-mortem study.

Cavum septi pellucidi (CSP), especially when longer than 6 mm, has been recognized as a neurodevelopmental anomaly associated with schizophrenia. The present post-mortem study was designed to determine the importance of linear parameters of CSP and to evaluate the possible differences of CSP in schizophrenic patients (n=25 out of 110 CSP+ brains) and normal persons (n=40 out of 110 CSP+ brains). According to our results, schizophrenia patients had significantly longer and wider CSP than normal individuals. Also, statistical analysis revealed a higher suicide rate in CSP-positive patients with schizophrenia.
