Female, 21 years old, with diplopia and headaches. The cerebral and cerebellar hemispheres and brainstem show normal signal intensity and morphology. No restricted diffusion is seen. The pattern of enhancement is within normal limits.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. There may be a small incidental choroidal fissure cyst on the right. The cerebellar tonsils terminate at the level of the foramen magnum but maintain a normal round contour.Signal intensity of the bone marrow is unremarkable. No significant abnormalities of the paranasal sinuses are detected. The odontoid process is mildly retroflexed and there seems to be a slight anterior shift of C2 relative to C3, findings which likely reflect normal variation.
Unremarkable evaluation of the brain with no specific findings to account for the patient's symptoms.
