Male, 3 months old, ex-36 weeker, with Treacher-Collins syndrome and mandibulofacial dysostosis. Image quality is reduced by motion artifact on most sequences. Given this limitation, the gross morphology of the brain is within normal limits. No large structural abnormalities are suspected. No areas of parenchymal signal abnormality or restricted diffusion are seen.A subdural fluid collection is present along the left frontal lobe measuring up to 7 mm in thickness but causing little if any mass effect on the adjacent brain parenchyma. The collection follows CSF signal on all sequences other than the FLAIR sequence where it is hyperintense to CSF. No evidence of acute intracranial hemorrhage is seen. The ventricles are normal in size and morphology.The pituitary region is unremarkable. The corpus callosum is fully formed and intact. The cerebellar vermis and hemispheres are normally formed. The pattern of white matter myelination is appropriate for age.
1.A subdural collection is evident along the left frontal lobe causing little if any mass effect on the adjacent brain parenchyma. Given its signal characteristics, this collection could represent an old subdural hematoma or a proteinaceous subdural hygroma.2.The remainder of the examination is within normal limits.
