Clinical question: 29-year-old female with sudden onset of headaches 2 weeks ago. Signs and symptoms: As above. Nonenhanced brain MRI:No acute intracranial process and negative diffusion weighted images.Examination demonstrate prominence of the vermian folia for patient's stated age of 29. Correlate with history and risk factors.Slight asymmetry of the lateral ventricles (right larger left) midline is believed to represent an anatomic variation areaThe anatomical and morphology and the signal intensity of brain parenchyma is otherwise within normal on all MRI sequences.The signal void of major intracranial arterial branches are identified.The signal intensity of intracranial venous sinuses remain unremarkable.Unremarkable calvarium, orbits, paranasal sinuses and mastoid air cells.
1.No acute intracranial process and negative diffusion weighted series.2.Prominence of vermian folia for patient of stated age.3.Unremarkable nonenhanced brain MRI otherwise as detailed above.4.Unremarkable visualized orbits and well pneumatized all paranasal sinuses and mastoid air cells.
