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.

The alternate name of the cisterna magna, cerebellomedullary cistern, is derived from the opening's location. In all 15 fetuses, the enlarged cisterna magna was first seen in the third trimester (gestational age range, 26 to 37 weeks).

Mega cisterna magna refers to a normal variant characterized by a truly focal enlargement of the CSF -filled subarachnoid space in the inferior and posterior portions of the posterior cranial fossa. It is an incidental finding on neuroimaging, and no imaging follow up is necessary.

Vaak wordt de diagnose dan bij toeval gesteld wanneer om een andere reden een scan van de hersenen gemaakt wordt. Enlargement of the cisterna magna has been reported to be associated with aneuploidy. 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. Normal variation - isolated mega cisterna magna is thought to be an anatomic variant with no clinical significance (12). Bodensteiner et al.

Per our knowledge, this is the first re-port of mega cisterna magna associated with catatonic schizophrenia. CASE REPORTS Case 1: A 26-year-old unmarried man from rural background presented with the chief complaints of Mega cisterna magna is an enlarged cisterna magna (≥10 mm on midsagittal images) with an intact vermis, a normal fourth ventricle, and, in some patients, an enlarged posterior fossa (16,20,21). It represents a truly focal enlargement of the subarachnoid space in the inferior and posterior portions of the posterior fossa. We report on a patient who presented a psychotic disorder (delusional type), and mega cisterna magna. This is the first report of such an association, and it is suggested that both the psychotic disorder and the mega cisterna magna may be the expression of a single underlying neurodevelopment abnormality.

It is a non pathological enlargement of retrocerebellar cerebrospinal fluid space. It may occur due to infection or inflammation in cerebrospinal fluid. Abnormality in chromosome can lead to retrocerebellar CSF space. Cisterna magna, also known as posterior cerebellomedullary cistern, is a dilation of the subarachnoid space located in the region posterior to the medulla and caudal to the cerebellum. Mega cisterna magna is defined as a large retro- and infracerebellar CSF space greater than 10 mm on midsagittal images, with intact vermis, normal fourth ventricle, and regular torcular location.
