Clinical presentationMRI featuresMacro-/microscopic anatomy

162/M
[14]
Ataxia, adiadocokinesiaNot reportedFirm tumor, with dural adhesion to the tentorium cerebelli
271/M
[11]
AtaxiaMultiple lesions; perifocal edema; homogenous enhancement after gadolinium injection; broad base in contact with the dura materFirm, hemispheric well-circumscribed tumor, adherent to the dura; the superficial portion appeared sharply demarcated from the adjacent cerebellar tissue, intralesional hemorrhage/necrosis.
380/M
[15]
Intracranial hypertensionSolid, homogeneously enhancing mass in the vermis and left cerebellar hemisphere; peritumoral edema causing mass effect and compression on the IV ventricleFirm and pseudo-encapsulated lesion without attachment to pia or dura; marginal hemorrhage and intralesional necrosis
470/F
[12]
Intracranial hypertensionCerebellar intra-axial lesion, with a smooth and slightly lobulated outer layer; minimal peritumoral edema; heterogeneous enhancement after gadolinium injectionRelatively well-circumscribed and firm mass with areas of necrosis and hemorrhage
568/M
[6]
Not reportedNot reportedDiscrete lesion with GBM-like characteristics
611/F
[13]
Ataxia, intracranial hypertensionIrregularly enhancing lesion located in the cerebellar vermis but characterized by bilateral extension; homogenous enhancement after gadolinium injectionFirm lesions reaching the surface of the cerebellum; white, glistening with areas of hemorrhage and necrosis
757/M
[16]
Intracranial hypertensionSolid lesion, isointense to the brain parenchyma on T1WI, hyperintense on T2WI, peripheral homogeneous enhancement after gadolinium injectionFirm intra-axial lesion without attachment to the dura mater
871/F
[17]
Intracranial hypertensionSolid, homogeneously enhancing, hemorrhagic mass in the cerebellopontine cisternWell-circumscribed mass with intralesional hemorrhage
933/F
[present case]
Intracranial hypertensionHomogenously enhancing cortical-subcortical lesion localized on the right cerebellar hemisphere, responsible for perilesional edema and characterized by evidence of dural infiltrationWell-circumscribed and firm mass; white, glistening, with intralesional evidence of necrosis
