Re: Head T2 weighted cross-section of the brain the cross section shows an obvious orbital asymmetry with the left eye ball being smaller and a low intensity structure is seen passing thru the center of the vitreous the asymmetry of soft tissues is partly becos of true asymmetry of the soft tissue and bony skeleton of the face ( possibly in conjunction with the orbital pathology ) and partly becos the section has gone obliquely i.e thru slightly diff. levels on both sides. can't comment about brain pathology without seeing additional sections. Diagnosis : Left sided micropthalmia with persistent hyperplastic primary vitreous ?
