 There is hemosiderin staining involving the choroid plexus of the lateral ventricles and the fourth ventricle, as well as within debris located in the dependent portions of the occipital horns bilaterally. Additionally, hemosiderin lines the occipital lobes bilaterally (left>right). There is evidence of colpocephaly with associated white matter loss, left greater than right. The corpus callosum is diffusely thinned. These findings are compatible with periventricular leukomalacia. There is slight dysmorphism of the quadrigeminal plate, and the CSF does not demonstrate flow on the sagittal CSF flow images at the level of the aqueduct, yet the aqueduct appears patent on the sagittal fiesta images.The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. No diffusion-weighted abnormalities to suggest acute ischemia are identified. There are no extraaxial fluid collections. Flow voids are present within the major vessels indicating patency. The mastoid air cells are clear.
1.Findings most compatible with colpocephaly and periventricular leukomalacia with evidence of prior ventricular hemorrhage. 2.There is slight dysmorphism of the quadrigeminal plate, and the CSF does not demonstrate flow on the sagittal CSF flow images at the level of the aqueduct, yet the aqueduct appears patent on the sagittal fiesta images.
