Headache [R51], Reason for Study: ^Reason: evaluate for structural abnormality History: severe intermittent headache and extended periods of unresponsiveness in former 26 week infant with heroin/cocaine exposure Brain MRINo evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Brain MRV3D MRV brain without-gadolinium enhancement with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus. There is however intra sinus linear signal voids especially at the level of distal superior sagittal sinus indicating intra-sinus fibrous strand which are normal findings.
