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.

� Cerebellar hypoplasia - Cerebellar hypoplasia is often associated with trisomies 13, 18 and 21 (14). The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata. Cerebrospinal fluid produced in the fourth ventricle drains into the cisterna magna via the lateral apertures and median aperture. Incidental mega cisterna magna. Images at higher levels confimed the presence of a normal posterior fossa and vermis distinguishing it from a Dandy-Walker malformation. 4 article feature images from this case 10 public playlist includes this case The importance of al mega cisterna magna is primarily not to mistake it for other abnormalities. 2 article feature images from this case Intracranial epidermoid cyst The cisterna magna is also known as the cerebellomedullary cistern.

In all 15 fetuses, the enlarged cisterna magna was first seen in the third trimester (gestational age range, 26 to 37 weeks). The cisterna magna ranged from 11 to 19 mm in size (mean, 12.9 mm). All 15 pregnancies resulted in phenotypically normal liveborn infants.

Magnetic resonance imaging (MRI) was used for those foetuses with mega cisterna magna. All of the foetuses were healthy by prenatal and postnatal examination,

It runs along the cerebellum, the part of the brain that is responsible for one's movement coordination, as well as for contributing to other functions such as alertness, speech and reaction to emotions such as fear Objective: The prevalence and clinical significance of isolated mega cisterna magna in both fetuses and adults is not yet well defined. It is therefore difficult to provide reliable parental counseling in cases of a fetal sonographic diagnosis of this anomaly. Mega cisterna magna refers simply to focal enlargement of the cisterna magna, the biggest of the subarachnoid cisterns, which is located posterior and inferior to cerebellum and dorsal surface of the brain stem, medulla oblongata, and superior to foramen magnum.

There is debate as to whether mega cisterna magna (MCM) arises from a pathologic insult; recent evidence suggests that it may be on the mildest end of the Dandy-Walker continuum. However, it can be considered an asymptomatic normal variation in which the posterior fossa appears mildly enlarged on imaging, typically with prominence of the subarachnoid space (SAS) posterior to the cerebellum Epidemiology A mega cisterna magna is thought to occur in 1% of all brains imaged postnatally.
