Cisterna magna Radiology Reference Article Radiopaedia

Gross anatomy. The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata at and above the level of the foramen magnum. CSF produced in the ventricular system drains into the cisterna magna from the fourth ventricle via the median aperture (of Magendie) and the lateral apertures (of Luschka) 1,2.. Several vessels and nerves course through the lateral. 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) 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

  1. The cisterna magna (or cerebellomedullaris cistern) is one of three principal openings in the subarachnoid space between the arachnoid and pia mater layers of the meninges surrounding the brain. The openings are collectively referred to as the subarachnoid cisterns.The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata
  2. cisterna: [noun] cistern 3: such as. one of the large spaces under the arachnoid membrane. one of the flattened vesicles comprising the Golgi apparatus and the part of the endoplasmic reticulum studded with ribosomes
  3. 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. Repeated measurement at 36 weeks had shown a dilation of 1.2 cm
  4. The cisterna magna is >10 mm in the transverse cerebellar view. Vermis: normal. Differential diagnosis: Blake's pouch cyst (expansion of the 4 th ventricle into the cisterna magna resulting in a unilocular, avascular cyst in the posterior fossa; vermis normal in size with upward rotation), arachnoid cyst (cyst in the cisterna magna with mass effect on surrounding structures; normal vermis)
  5. Mega Cisterna Magna and Arachnoid are both types of cysts that occur in the central nervous system and contain cerebrospinal fluid, or CSF. While they are very similar, it is important to make a correct diagnosis between the two in order to ensure proper planning and treatment and in order to properly diagnosis, a clear differentiation should be made
  6. Mega cisterna magna. 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. In mega cisterna magna, unlike in DWM: The cerebellum is not usually hypoplastic

Cisterna magna is the biggest CSF filled space in brain. Prominent cisterna magna is a slight larger (more than normal) cisterna magna. It is not a pathological or diseased condition and considered as normal variant. If very large can produce symptoms due to pressure on normal brain The cisterna magna (or cerebellomedullary cistern) is a large cistern between the cerebellum and medulla.It lies between the cerebellum and the dorsal surface of the medulla. As with all cisterns of the brain, this cistern is an opening in the subarachnoid space created by the separation of the arachnoid and pia mater.. The cisterna magna (cerebellomedullary cistern) allows CSF to drain via. cisterna magna A region in the brain posterior to the medulla oblongata , below the cerebellum ; cerebrospinal fluid enters from the fourth ventricle . Synonyms [ edit Cisterna magna enlarged - >10mm. Free communication with perimedullary subarachnoid space. The cisterna may be so large that it extends laterally, posteriorly and superiorly far beyond the normal anatomic limits of the cisterna magna. The cisterna may also extend superiorly through a posterior dehiscence of the tentorium cerebelli The cisterna magna contains cerebrospinal fluid and is located behind the cerebellum in the posterior fossa of the brain. It communicates with the fourth ventricle via the foramina of Magendie and Luschka. Measurement of the anteroposterior diameter of the cisterna magna can be useful in diagnosing posterior fossa abnormalities

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. A mega cisterna magna (cisterna magna ≥10 mm; Figure 10) is known to result from a defect of the posterior membranous area during embryogenesis. 21 We speculate that in this condition, Blake's pouch probably persists and expands posterior to a normally formed cerebellum and vermis, but unlike a persistent Blake's pouch (see below), fenestration occurs late, leaving behind an expanded.

Objective: The purpose of this study was to evaluate cisterna magna size of the fetuses between 16 and 24 weeks of gestation, and to establish a normogram for cisterna magna measurements during gestation. Methods: A prospective study of normal singleton pregnancies was established. Measurement of the fetal cisterna magna was performed by transabdominal ultrasonography between 16 and 24 weeks. Mega-cisterna magna is defined as a cisterna magna > 10 mm in diameter, with no change in the cerebellar vermis .

Eleven cases of enlarged cisterna magna were found in a series of 3000 computerized tomography scans. We believe mega cisterna magna by itself is not related to any specific symptoms and may not require further study or treatment Causes of an enlarged cisterna magna include cerebellar hypoplasia, communicating hydrocephalus, and normal variation. Cerebellar hypoplasia is a frequent finding in the trisomies and therefore a careful search should be made for associated cardiac anomalies, growth retardation, and polyhydramnios
