Cerebrotendinous xanthomatosis in an adult male (CT and MRI)

Download

Cerebellar parenchymal abnormalities in a 40-year-old man with cerebrotendinous xanthomatosis. (A) and (B) Axial CT images show low-density lesions in both cerebellar hemispheres. (C) The axial T1-weighted image shows low-intensity areas in the dentate nuclei and the deep cerebellar white matter bilaterally. (D) The axial T2-weighted image shows hyperintensities in the bilateral cerebellar deep white matter and hyperintensities in the deep white matter of the cerebellum bilaterally. (E) The axial FLAIR image shows low-signal intensity consistent with cerebellar vacuolation in the same areas. (F) Susceptibility-weighted imaging reveals hypointensities in the bilateral dentate nuclei compatible with microcalcifications. (Source: Ma C, Ren YD, Wang JC, et al.
