Male, full-term 7-year-old infant with jerking episodes of bilateral upper extremities. A 4 mm T1 intermediate and T2 hypointense, susceptibility inducing lesion is evident along the body of the left caudate nucleus. This is located at the superior most aspect of the caudothalamic groove. No significant associated edema or mass effect is observed. There may also be a tiny focus of susceptibility overlying the right occipital horn but this is equivocal. Elsewhere, the morphology of the brain is appropriate for gestational age. No areas of edema or mass effect are detected. No large extra-axial fluid collections are observed. The ventricles are normal in size and morphology.The pituitary region is unremarkable. The brainstem, cerebellar vermis and cerebellar hemispheres are normally formed. The corpus callosum is fully formed and intact. The pattern of white matter myelination is appropriate for age.
1.A susceptibility inducing lesion is evident along the body of the left caudate nucleus which which could represent a small focus of hemorrhage. The age of this lesion is difficult to ascertain though it is favored to be subacute to chronic.2.A questionable focus of susceptibility overlying the right occipital horn would also support the possibility of a prior hemorrhagic event.3.Evaluation of the brain is otherwise unremarkable.Discussed with Dr. Elios at 12:00 PM on 6/3/16.
