Clinical question: chronic headaches post head-injury w/o prior imaging. Signs and Symptoms: headache Pre and post enhanced brain MR:No acute intracranial finding and negative diffusion weighted series.There is normal anatomical development and morphology of brain with normal signal intensity on all MRI sequences, including susceptibility sequence.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination. Normal signal void of all major arterial branches are identified.There is no abnormal enhancement of brain or the leptomeninges.There is normal signal intensity of the intracranial venous sinuses with normal pattern of enhancement. Normal signal intensity of calvarium and scalp without abnormal enhancement.Unremarkable images through the orbits and without abnormal enhancement.Normal signal intensity of all paranasal sinuses, mastoid air cells and the middle ear cavities.
Unremarkable pre and post enhanced brain MRI.
