Female, 22 years old, with type 1 diabetes, 23 weeks pregnant, with persistent headache, worse when supine. MRI:The cerebral and cerebellar hemispheres and brainstem show normal signal intensity and morphology. No restricted diffusion is seen.No evidence of parenchymal edema, mass, or mass effect is seen. There is no evidence of intracranial hemorrhage or abnormal extra-axial fluid. The ventricular system is normal in caliber and morphology. Signal intensity of the bone marrow is unremarkable. No significant abnormalities of the paranasal sinuses are detected.MRA:The intracranial arterial vasculature demonstrates normal morphology and caliber. No significant stenosis or occlusion is seen. No aneurysms are detected within the limitations of technique.MRV:The dural venous sinuses and major deep intracranial veins demonstrate flow related signal compatible with patency.
1.Unremarkable MRI evaluation of the brain with no specific findings to account for the patient's headaches.2.No abnormalities are detected on either the MRA or MRV.
