cisterna magna The cranial subarachnoid space between the medulla and the cerebellum; the foramina of the fourth ventricle open into it. Cerebrospinal fluid flows from it into the spinal subarachnoid space.

In prior studies of cisterna magna enlargement, however, those fetuses with abnormal chromosomes have had other sonographic abnormalities in addition to a large cisterna magna. Abdullah Keleş, MD, Mehmet Volkan Harput, MD, and Uğur Türe, MDDepartment of Neurosurgery, Yeditepe University School of Medicine, Istanbul, TurkeyWe present Video shows what cisterna magna means. A region in the brain posterior to the medulla oblongata, below the cerebellum; cerebrospinal fluid enters from the fo The cisterna magna depth measured 5 +/- 3 mm; the largest cisterna magna measured 10 mm in depth. In the absence of other findings to suggest a posterior fossa lesion, a prominent cisterna magna is unlikely to be clinically significant. A boy had been born to a 28-year-old mother who had chronic hepatitis B virus (HBV) infection, gestational diabetes, and late prenatal care beginning at 19 weeks of gestation. At 29 weeks of gestation, an enlarged cisterna magna of 1.1 cm had been discovered on fetal ultrasonography.

The cisterna magna is also known as the cerebellomedullary cistern. A mega-cisterna magna, is a controversial entity among experts. In general however, the term is applied to non-pathological prominance (usually exceeding 10 mm in antenatal imaging) of the retro-cerebellar CSF space and not associated with cerebellar abnormalities. There is a normal vermis and normal cerebellar hemispheres. Methods: We reviewed 19,301 consecutive CT/MRI of the brain. Isolated mega cisterna magna was observed in 49 cases.

The cisterna may also extend superiorly through a posterior dehiscence of the tentorium cerebelli. Enlarged cisterna magna and the Dandy-Walker malformation: factors associated with chromosome abnormalities.
