A Mega cisterna magna refers to patients with enlarged CSF retrocerbellar cisterns in the posterior fossa, usually larger than 10mm in antenatal imaging. There will be normal cerebral morphology, also referred to as no abnormalities in the cerebellar. Isolated mega cisterna magna was observed in 49 cases. A battery of neuropsychological tests was performed in 18 adults with this anomaly and in 18 controls who had no brain anomaly on CT/MRI.

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).

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 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. Epidemiology A mega cisterna magna is thought to occur […] His birth weight was 4850 g, birth length was 53 cm, and birth frontal occipital circumference was 35.5 cm. The patient was admitted to the nursery, was monitored closely for hypoglycemia, and was administered the HBV vaccine and immunoglobulin.

His cerebrospinal fluid was cytologically and biochemically normal. Cranial MRI revealed 1.5 cm diametered mega cisterna magna in the retrocerebellar region. They mentioned that such marked enlargement of the cisterna magna is rare.

We present here two cases of mega cisterna magna associated with mania and catatonic schizophrenia. 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.

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. The mega cisterna magna freely communicates with the fourth ventricle and the cervical subarachnoid space (Figs 1.9 and 1.10). A mega cisterna magna is a controversial subject. In general, however, the term refers to non-pathological enlargement of the retrocerebellar CSF space, not associated with cerebellar abnormalities (normal cerebellar vermis and hemispheres). A Mega cisterna magna refers to patients with enlarged CSF retrocerbellar cisterns in the posterior fossa, usually larger than 10mm in antenatal imaging. There will be normal cerebral morphology, also referred to as no abnormalities in the cerebellar.

Megacisterna magna Es una malformación congénita consistente en una cisterna magna prominente, que puede extenderse lateral, superior y posteriormente más allá de sus límites anatómicos y que se comunica libremente con el espacio subaracnoideo perimedular. 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. [operativeneurosurgery.com] Epidemiology and Demographics The Dandy-Walker complex is a genetically sporadic disorder that occurs one in every 25,000 live births, mostly in females.

Mega cisterna magna is a condition in which the cisterna magna, the subarachnoid cistern below the fourth ventricle, is enlarged. It has been proposed to be due to a delayed rupture of Blake's pouch rather than a failed rupture.
