A 22 year-old female with a medical history of migraines and obesity who presents to the Emergency Department with a headache.

Her headache was gradual in onset, but has progressively worsened and has not been relieved with NSAIDs.

She describes the headache as dull and pounding with photophobia and phonophobia.

She also notes associated nausea but no vomiting, and no associated neurologic complaints.

She does note that she thinks during a previous ED visit at an outside hospital she was told she may have “high pressure in her head” but she does not remember the details and is not on any medication for it.

An LP was performed and the opening pressure was mildly elevated at 33 cm H2O that decreased to 18 cm H2O with removal of 20 cc of fluid.

The patient was diagnosed with Idiopathic Intracranial Hypertension and started on Diamox with outpatient neurology and ophthalmology follow-up.
