 Brain: There is a subdural collection over the left posterior occipitoparietal area that extends over the posterior right occipital lobe and is near CSF signal on T1 and T2 weighted imaging; finding are favored to represent chronic subdural hemorrhages. The septum pellucidum is present anteriorly with thinning/absence in the midportion, which may be due to prior hydrocephalus. No hydrocephalus is seen on the current examination. The lateral ventricles are mildly dysmorphic and there is diminished supratentorial white matter in the parietooccipital lobes bilaterally. A developmental venous anomaly is noted in the right parietal lobe. There is no midline shift or mass effect. No evidence of heterotropia. There is minimal diffuse dural enhancement, which may be reactive to the subdural collections. There is no diffusion abnormality. Pituitary: Dedicated images through the sella demonstrate a grossly unremarkable pituitary gland with normal T1 shortening of the posterior pituitary and normal diffuse homogenous enhancement. There is no obvious hypoplasia of the optic nerve or chiasm. There is mild calvarial deformity involving the posterior planum sphenoidale, which appears mildly depressed without evidence of platybasia.
1.The pituitary is within normal limits for age without findings to suggest hypoplasia or adenoma. No evidence of heterotopia as questioned. 2.Dysmorphic lateral ventricles with septum pellucidum present anteriorly and very thin/deficient in its midportion, finding which may be related to prior hydrocephalus. Priors may be helpful for confirmation if available. No findings to suggest hydrocephalus on the current study.3.Bilateral subdural fluid collections are nonspecific but favored to represent chronic subdural hematomas.4.Diminished white matter in the parieto-occipital region.5.Focal calvarial deformity involving the posterior planum sphenoidale which is angulated inferiorly. No evidence of platybasia.
