HeadacheClinical question: Please evaluate craniocervical junctionSigns and Symptoms: Headache, dizzy, scintillations, scotomata The CSF spaces are appropriate for the patient's stated age with no midline shift. There is no evidence for Chiari malformation. The lateral ventricles are nondilated. A 3 millimeters cyst is present in the right choroid fissure.No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate a couple minor opacities. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
No obvious cause for the patient's headache is appreciated. A 3 mm cyst in the right choroid fissure is most likely incidental and of little clinical significance
