 Brain MRI:The lateral ventricles are prominent with irregular borders associated with white matter volume loss and a very thin corpus callosum.Assuming a 4 month old gestational age brain (correcting for 28 weeks prematurity in this 7-year-old male), there is diffuse hypomyelination.There is a punctate focus of susceptibility hypointensity at the expected location of the right terminal matrix, and questionably in the similar location on the left. Additionally, there is evidence for old hemorrhagic products layering within bilateral occipital horns.The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The mastoid air cells are clear. Complete spine MRI:Bibasilar atelectasis is presumed secondary to the patient's sedated status.There are no fractures or subluxations. The marrow signal is benign. The cord is normal in signal. The cervicomedullary junction is normal. The cerebellar tonsils are in appropriate position. The conus is normal in signal and morphology and terminates at L2. The visualized paraspinal contents are unremarkable. There are no segmentation anomalies or stenoses.
1.The lateral ventricles are prominent with irregular borders associated with white matter volume loss and a very thin corpus callosum consistent with periventricular leukomalacia.2.Diffuse hypomyelination for age.3.There is a punctate focus of old hemorrhage at the expected location of the right terminal matrix, and questionably in the similar location on the left. Additionally, there is evidence for old hemorrhagic products layering within bilateral occipital horns.4.Negative complete spine MRI.
