Moderate symmetrical fluid dilatation of the lateral ventricles overlying the bilateral choroid plexi is noted. The 3rd and 4th ventrices grossly looks normal. No midline shift of the intra-cranial structures or obvious space occupying lesion. The brain parenchyma, sulci and the gyri are normal. No intra-cranial haemorrhage or sub-dural effusion. Corpus callosum, cavum septum pellucidum, falx cerebri, cerebellum, posterior fossa, vermis, thalami and peri-callosal vasculature plus vein of Galen are uneventful.
Trans-cranial spectral Doppler evaluation of the circle of Willis shows elevated resistive indices within the right and left middle cerebral arteries (Rt = 0.95; Lt = 0.95) with absent end diastolic flows bilaterally.
