21 Αυγ 2024 · Typically seen as prominent retrocerebellar cerebrospinal fluid (CSF) appearing space with a normal vermis, normal 4 th ventricle, and normal cerebellar hemispheres. An enlarged cisterna magna usually measures >10 mm on midsagittal images.
The cisterna magna (posterior cerebellomedullary cistern, [1] or cerebellomedullary cistern [2] [3]) is the largest of the subarachnoid cisterns. It occupies the space created by the angle between the caudal/inferior surface of the cerebellum, and the dorsal/posterior surface of the medulla oblongata (it is created by the arachnoidea that ...
10 Ιαν 2017 · A 20 year old who had a slightly enlarged cisterna magna with a retrocerebellar cyst-like focus (*) on sagittal (left) and coronal (middle) reformats from an axial NECT (right). The falx appears to partially traverse through the cyst (arrows) on an axial image (right).
29 Μαΐ 2023 · Radiographically, the mega cisterna magna appears as a prominent retrocerebellar CSF appearing space measuring greater than 10 mm on mid-sagittal images with a normal cerebellar vermis and ventricular caliber.
These cysts posterior to the cerebellum, presenting in children younger than 5 years, are labeled developmental retrocerebellar cysts (DRCCs) under a new classification in relation to neuroendoscopy. Methods: DRCC was categorized as type 0 for asymptomatic enlarged cistern magna and was not treated.
22 Αυγ 2019 · The CT cisternogram images demonstrate the anatomy of the basal cisterns in high resolution and the site of CSF leakage can be accurately determined. The anatomy of the cranial nerves and vessels within the basal cisterns is shown in great detail.
1 Αυγ 2019 · These cysts posterior to cerebellum, presenting before five years are labelled developmental retrocerebellar cysts(DRCC) under a new classification in relation to neuroendoscopy.
