PTEN and Lhermitte-Duclos disease: In the current literature, different neuroimaging features associated with PTEN mutations have been reported, including cerebellar dysplastic gangliocytoma (Lhermitte–Duclos disease (LDD)), meningioma, vascular malformations [12], localized malformations such as focal cortical dysplasia, white matter abnormalities [13], dilated Virchow–Robin spaces [14] and polymicrogyria [15].
