 The ventricles and sulci are within normal limits. There is a cavum septum pellucidum et vergae. There are prominent cystic areas in the frontal periventricular white matter corresponding to the questioned abnormality on recent fetal MRI. The one on the left measures up to 1.6 cm while the one on the right measures up to 1.2 cm, located along the superolateral aspect of the frontal horns, with mild mass effect on the presumed ventricular margins. These are of CSF signal intensity on all sequences. The basal cisterns remain patent. There is no midline shift or mass effect. There is irregular T1 hyperintensity, T2 hypointensity, and associated susceptibility in the supracerebellar cistern, appearing below the tentorium, felt to relate to likely subacute blood products. There are no areas of pathological enhancement. There is no diffusion abnormality. No extra-axial fluid collection is identified. Myelination appears appropriate for corrected age.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is a questioned defect along the posterior aspect of the palate, which may represent a cleft palate.
1. Redemonstration of eft greater than right nonenhancing CSF signal intensity cystic structures along the superolateral aspects of the frontal horns, with mild mass effect on the adjacent ventricular margin. These are favored to represent periventricular cysts of the newborn, such as connatal or subependymal cysts, and not felt to relate to periventricular leukomalacia. Follow-up imaging may be obtained as clinically indicated.2. Prominent subacute blood products just under the tentorium in the supracerebellar cistern. While somewhat unusual in location, these may be related to subdural hemorrhage from birth.3. Cleft palate suggested. Please correlate with direct inspection.
