Cavum Septum Pellucidum Symptoms, Causes, Cyst, Treatment

Cavum septum pellucidum is sometimes associated with the cavum vergae (CV). Septum pellucidum is laminated with thin vertical membrane separating right and left ventricle. It is basically cerebro spinal fluid filled between the area of septum pellucidum, common anatomical variation. It is present in normal fetus. It may also referred as 6th ventricle. Cavum vergae is the posterior extended portion of the cavum septum pellucidum, but it may somtime exist separately. Anteriorly it is cavum septum pellucidum, outside it is related to corpus callosum, superiorly it is related to the body of corpus callosum, inferiorly it is related to transevrese fornix.

Cavum Septum Pellucidum Symptoms


Not proper symptoms are shown. Physical examination did not shown any abnormal symptoms. Sort of headache may diagnose this pattern by drawing headache chart. Headache may be of tension type or we can say migraine. it may last for 15 days or up-to 3 months. Headache may be of aggravated type or by some physical activity like climbing stairs or walking. Nausea, vomiting, photophobia and phonophobia may also seen. Patient who has headache with these symptoms fulfills the criteria of cavum septum pellucidum. From case history, patient may feel chronic daily headache (NSAIDs will not provide relief). Their symptoms may be connected with CNS abnormalities.

Cavum Septum Pellucidum Causes


Causes of cavum septum pellucidum are mostly connected with other CNS disorders like shizophrenia, post traumatic disorder, chronic brain trauma, seizures, personality changes and traumatic brain injuries. Extentsion of lesion in the cavum destroys the vessels causing suppression of the septum triangle and also optic nerve pathways.

During fetal 12th week of development, space in cavum septum pellucidum forms and round about at 20th week this space starts to close, this closure ends at near birth. This fusion will lead to development of other brain portions. If this closure will not be on time, limbic development interrupts, preservation will be shown into adulthood.

Cavum Septum Pellucidum Cysts


These are the rare lesions. In its transverse diameter it will increase and gradually increase more with time. The outer layer margins will become convex. They compress the midbrain and cause obstruction on large scale leading to hydrocephalus. They also effect the drainage of occipital temporal portion of lateral ventricles.

Sypmtoms of cavum septum pellucidum cysyt increase in intracranial pressure, morning headache becomes worse with time. Ultrasound, CT scan and MRI diagnose the cyst. No such treatment is required. If the patient is suffering from hydrocephalus then CSF shunting will be done and catheter drainage of the cyst will be required.

Cavum Septum Pellucidum Treatment


Dihydroergotamine is recommended for the migraine, or any preventive medication will be given for chronic migraine. Βeta antagonist with calcium channel blocker, anti depressants and anti-convulsants are used to avoid the cardiovascular and cerebral damage and in order to improve the patient’s life. Sometime neurosurgery will be performed. If the patient is suffering from hydrocephalus then CSF shunting will be done and catheter drainage of the cyst will be required. Vraniotomy and open fenestration will be performed, stereotactic fenestration (perofrmed under local anesthesia) , neuroendoscopic surgery (reduce hazard of injury to anatomical sturcutures and allows better control of bleeding) will be performed.
