We highlight a case of intracranial hypertension secondary to exogenous testosterone in a female-to-male transgender patient and present a systematic review of similar cases. Our review identified 19 female-to-male transgender individuals with intracranial hypertension. The mean age was 24.2 years and most common presenting symptom was headache (78.9% of patients). The most frequently associated ocular symptoms were transient visual obscurations (42.1%) and blurred vision (21.1%). Onset of symptoms occurred concurrently with exogenous testosterone therapy in 89.5% of the patients. The most common treatments were acetazolamide (89.5%), topiramate (31.6%), and alteration in hormone regimen (21.1%); four cases required surgery. These findings aid clinicians treating intracranial hypertension in patients undergoing gender affirmation therapy in a conscientious, patient-centered manner.
