Cerebral 3 ventricle colloid cyst
Cerebral 3 ventricle colloid cyst tumors occur in 10-15% of such sites - a. 3 ventricle colloid cyst of the brain is more commonly found in adults. Until the dispute is the question that it could be classified as a cyst of the brain tumors.
Cerebral 3 ventricle colloid cyst is congenital and observing cases is hereditary. Identified a specific gene that is transmitted by the autosomal - dominant mechanism. According to some sources, the brain ventricle colloid cyst III neuroepithelial cells originate in the brain and other data - endodermal localized ectopic cells or bronchial and lung tissues.
3 ventricle colloid cyst is a benign brain mass like gelatin containing thin walls. 3 ventricle colloid cyst localized in the brain side of the front part of its roof, and its projection in the intraventricular foramina of Monro.
Brain colloid cyst wall epithelium (like a cube or a column) generating mucosa (like gelatin) content, which accumulates within the cyst capsule. In children, the brain cyst may contain hemorrhages.
Cerebral 3 ventricle colloid cyst symptoms
Brain cysts are asymptomatic and rarely can cause headaches. Cyst symptoms occur most frequently in cases of complaints of headaches. Brain cyst symptoms are most commonly found in adults in the form of headache, internal pressure in the skull and acute occlusive hydrocephalus in a pair of lateral ventricles.
Other neurological symptoms of cerebral cyst include the patient's mental status changes, nausea, vomiting, dizziness, epileptic seizures, and sudden weakness in the legs. The End Abuse (weakness in the legs) may rarely be associated with other tumors of the brain and may also be corticospinal tract (leading to his feet fibers) stretching results during the hydrocephalus volume increase.
In the most severe cases of cerebral 3 ventricle cyst happens the patient's sudden death. This can be done by the mechanical pressure of the heart rhythm regulation center of the brain cyst, which was located in the hypothalamus. Acute blockade cerebrospinal fluid (liquor) by an impression of the brain in tentorial camping may become the cause of the patient's death.
Cerebral 3 ventricle colloid cyst differential diagnosis
Cerebral 3 ventricle colloid cyst differential diagnosis revealed with a wide range of 3 ventricle tumors. These tumors usually occur without the 3 ventricle of the brain and able to protect their space from brain parenchymal outside pressure. At the same time, these tumors may affect cerebrospinal fluid (liquor) block. Vascular plexus papilloma found in the 3 ventricle space in the first 20 years of life. 3 ventricle space identified in 10-30% of tumors can get into this space from the lateral ventricles through the intraventricular foramina of Monro.
Neuracitomas are intraventricular benign tumors of the nervous system that are composed of mature ganglion cells in children and young patients with lateral and 3 ventricle areas.
Microscopy is often mistakenly diagnosed neurocytomas as an oligodendroglioma or ependymoma, so its neurocytoma disease may be more common than it used to be before. Intraventricular meningiomas can be found in 15-17% of cases of children suffering from meningioma and only 1.6% of cases of adults suffering from meningioma. Meningiomas can be originally from the lateral ventricular space (rarely) or grew from the skull base on the bottom of the 3 ventricle (often).
As was described above, on the cerebral 3 ventricle major injury influence appears from brain parenchyma. The majority of these injuries developing from glial tumors, piloid astrocytomas, fibrous astrocytomas, protoplasmatic astrocytomas, subependymal giant cell astrocytomas, including multiforme glioblastomas and ependymomas. Tumor metastases can be extended on the cerebral 3 ventricle from roof, bottom, lateral margins or the vascular walls. Metastases are most often found from the lungs, large intestine, kidney, and mammary gland. In these cases (tumor cell metastases) prognosis is poor and death occurs as a result of the underlying disease progression.
Suprasellar (localized above the Turkish saddle) germinomas and craniopharyngiomas can extend on the 3 ventricle bottom from the skull base (skull in the middle fossa). Suprasellar localized pituitary gland macroadenoma also may interfere in 3 ventricle. Vision Loss and narrowing its area, endocrine pathology, and headaches - these are the most common symptoms in these cases.
Other cysts of the front part of the brain III ventricular can be epidermoid cysts, dermoid cysts, and neural cysticercosis. Epidermoid and dermoid cysts are rarely found in 3 ventricle as neurocysticercosis is common in eastern Europe, countries in Asia, Central and South America, Mexico and Africa. Developing of neurocysticercosis in the cerebral 3 ventricle followed the development of hydrocephalus inflammatory lesions such as pyogenic abscess and granulomatous diseases (tuberculosis and fungal disease) is relatively rare damage cerebral 3 ventricle. Other injuries such as sarcoidosis and histiocytosis can act on the cerebral 3 ventricle on the side of its bed and hypothalamus.
Cerebral 3 ventricle colloid cyst diagnosis
Colloid cyst contents do his research at neurovisualisation. Colloid cyst can be accidentally discovered during computed tomography of the brain, or when a patient has neurological symptoms and signs of pressure on the inner skull, causing acute obstructive hydrocephalus doctor may doubt the existence. Brain and skull base CT scan, usually, 3 ventricle shows homogeneous hyperintensity within the mass at the level of intraventricular foramina of Monroe.
Acute occlusive hydrocephalus with swelling parenchyma may occur with cerebrospinal fluid block to the direction III ventricular. On T2 regime of the brain magnetic resonance imaging (MRI) colloid cyst may be shown hypo-or hyperintensity and on FLAIR regime shows periventricular swelling and hydrocephalus in the acute stage, as intensively pronounced cerebral parenchyma around the lateral ventricle.
Cerebral 3 ventricle colloid cyst treatment
Neurosurgical intervention (surgery) is shown after the evaluation of such factors as the patient's age, her neurological symptoms, and the cyst size. The risk of sudden death based on the operation is recommended 3 ventricle 1.5 cm, and it to an over-sized cyst in young people, regardless if it is asymptomatic. Cerebral 3 ventricle cyst patients who have neurological symptoms, should be operative neurosurgical treatment.
Cerebral 3 ventricle colloid cyst as a neurosurgical treatment option includes endoscopic cyst removal, also open to a different approach to operations, such as hemispherical transcortical or interhemispheric transcallosal approach.
