Sickle cell patient with persistent severe headaches, evaluate for signs of increased pressure and/or lesions MRI brain:No restricted diffusion to suggest acute ischemia. The signal intensity of the brain parenchyma is within normal limits. There is no abnormal enhancement within the brain parenchyma. The ventricles, sulci, and basal cisterns are normal in size. There are no masses, mass effect or midline shift. The cerebellar tonsils are normal in position. There is no evidence of intracranial hemorrhage or extraaxial fluid collections. Polypoid mucosal thickening of the maxillary sinuses. The remaining paranasal sinuses and mastoid air cells are grossly aerated. The orbits are unremarkable.MRA brain:MRI angiogram is somewhat motion graded yet demonstrates patent anterior and posterior intracranial circulations without evidence of flow limiting stenoses, significant atherosclerosis, or aneurysms.
