Structural brain abnormalities have also been found in many psychotic illnesses, including schizophrenia and there are findings of association of large ventricles with chronic and deteriorating psychosis. It is possible that a large ventricular system may increase the likelihood of catatonia with a chronic course. Cavum Septum Pellucidum (CSP) and Cavum Vergae (CV) are structural abnormalities that have been associated with Schizophrenia. This is a case report of the presence of persistent CSP and CV in a patient diagnosed with schizophrenia with catatonia. Conclusion: Although there are several reports of the findings of a persistent large CSP and CV in patients with Schizophrenia, it is questionable whether the CSP and CV are the cause of the Catatonia or their occurrence is a mere coincidence.展开更多

Intraventricular cavernomas of the body of the lateral ventricle are usually treated by the transcallosal approach. Clinical Presentation: We present a case of a fifty-eight year old man with a septum pellucidum cavernoma successfully treated operatively by means of the inferior parietal transcortical transventricular approach. This unusual and scarcely documented tumor was situated at the posterior third of the septum pellucidum. The patient had a good recovery with no focal deficit. Conclusion: Septum pellucidum cavernomas are extremely rare lesions. Inferior parietal transcortical approach is a safe alternative to the commonly used transcallosal approach for lesions of the posterior half of the septum pellucidum.展开更多

Surgery as the main therapeutic procedure for this lesion is a challenge to neurosurgeons. We analyzed the clinical characteristics and pathological features of septum pellucidum tumor in 41 patients and compared the curative effects of frontal transcortical, trans-sulcal and interhemispheric transcallosal approaches. Methods Clinical characteristics and the pathological features of septum pellucidum tumor were investigated retrospectively in 41 patients. The differences in postoperative residual rates, extents of tumors and resection of normal brain tissues after use of the three approaches in these patients were analyzed statistically. Results Septum pellucidum tumor is more likely to attack young or middle-aged persons. The tumor mainly presents itself as a central neurocytoma or cerebral low-grade glioma in pathology and manifests as intracranial hypertension clinically. No difference was found in the extent of tumor resection but significant difference in the extent of normal brain tissue resection and in postoperative disability rate among the three approaches. The transcortical approach brought about the most serious injury to brain tissue and the highest disability rate, Whereas the frontal transcallosal approach the lightest injury and the lowest disability rate. The injury to brain tissue and the disability rate brought about by the front trans-sulcus approach were between the above two approaches. Conclusions Operation is still regarded the major treatment for septum pellucidum tumor. Transcallosal and trans-sulcus approaches are fit with the concept of minimally invasive surgery, and transcallosal approach is the first choice for septum pellucidum tumor.展开更多

Here, we described a patient with childhood-onset schizophrenia who had severe psychiatric symptoms such as auditory hallucinations and persecutory delusions, and etc. We reexamined all his possible medical conditions and found that the patient had an abnormally enlarged cavus septum pellucidum （CSP） combined with cavum vergae （CV） （maximum length 〉30 mm）. Some reports suggested that abnormal CSP （length 〉6 mm） has a significant association with schizophrenia. However, abnormally large CSP or CSP/CV and related prognosis were reported rarely. This case suggested that abnormally enlarged CSP or CSP/CV may worsen the prognosis.展开更多
