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.

Sie gehört zu den Fehlbildungen des Dandy-Walker-Komplexes. 2 Quellen ↑ Schneider et al., Die Geburtshilfe, Springer-Verlag, 2013 De cisterna magna, of cisterna cerebellomedullaris, is de grootste opening in de subarachnoïdale ruimte van de hersenen, tussen het spinnenwebvlies en het zachte hersenvlies. De cisterna magna bevindt zich tussen het cerebellum en de rugzijde van de medulla oblongata.

Mega cisterna magna is the enlargement of subarachnoid space containing cerebrospinal fluid. 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.
