A 35-year-old man presents with headache and visual disturbances. He denies any fever, weight loss, or other symptoms. His vital signs are within normal limits, and the rest of the physical examination is unremarkable.
These symptoms could be caused by a variety of conditions, including migraines, glaucoma, or a neurological condition like a brain tumor or pseudotumor cerebri. However, without more information, including a more detailed ophthalmologic and neurological examination and possibly imaging studies, it is impossible to confidently diagnose his condition.
