Figure 1.
Brain MRI of a 3.5-year-old girl. Sagittal (A) and axial T2 weighted images (B) show enlarged retrovermian cistern and left pericerebellar subarachnoid space (black and white arrowheads). Sagittal T1 weighted image (C) shows thinning of the isthmus of the corpus callosum (white arrow). Sagittal (A,C) and axial (D) images show a normal conformation of the cerebellar hemispheres and vermis. MRI remained unchanged in comparison with the previous one performed at the age of 2.4 years old, except for a progression of the myelination.
