I did brain MRI this morning and one of the results was: there is evidence of cavum septum pellucidum what does that means?
Likely nothing wrong: The "septum pellucidum" is an anatomical structure in the brain that separates what are known as the 3rd ventricles. In the fetus, it actually begins as a "cavum" form (meaning the structure is split down the middle). Normally, it later after birth. But sometimes it doesn't or in other circumstances it may re-split (head trauma, seen in boxers as well as seen in nontraumatic conditions). ...Read more
Probably normal: The septum pellucidum is a normal midline structure in the brain. When this thin membrane is split it forms a cavity. This may represent a normal anatomic variant or a incomplete form of midline developmental anomalies such as dysgenesis of the corpus callosum. Enlarged cavum septum pellucidum have variously been associated with schizophrenia, affective disorder&other neuropsychiatric disorders. ...Read more
Cavum septi pellucid: From http://neuro.Psychiatryonline.Org/article.Aspx?Articleid=100939 - enlarged cavum septi pellucidi (csp) is a neurodevelopmental anomaly associated with schizophrenia...A small csp is common in a large proportion of healthy control subjects and is therefore considered to be a "normal variant." determination of how large a csp must be in order to reflect pathology is unclear. Normal is 1-4 mm. ...Read more
Fetal brain: Cavum septum pellucidi is a fluid-filled space less than 10 mm wide between the frontal horns of the lateral ventricles of the brain, and below the anterior portion of the corpus callosum (connects the two hemispheres of the brain). If it is not seen on fetal head ct between 18 and 37 weeks, midline malformations may be present, and a thorough exam of the fetal CNS should be done. ...Read more
