Abstract PDF: Persistent genital arousal disorder (PGAD) is characterized by unwanted and distressing genital sensations that are not associated with concomitant sexual interest or thoughts. Several etiologies have been proposed, but the underlying mechanism of the condition remains unclear. In this report, we describe a case of PGAD presenting with primary headache associated with sexual activity (PHASA). A 57-year-old female with no history of headache experienced recurrent, unwanted episodes of genital arousal lasting 3 to 5 days for 4 years. One day, she began to experience intense genital arousal that she had never experienced before. On the fourth day of arousal, while attempting intercourse with her partner, she experienced an abrupt explosive headache, which was repeated during another session of intercourse a week later. The patient underwent laboratory tests, as well as brain magnetic resonance imaging (MRI) and magnetic resonance angiography, all of which showed normal findings. She was referred to a sexual medicine specialist and prescribed amitriptyline, escitalopram, and propranolol with a diagnosis of PGAD. Her sexual arousal gradually diminished, and when she stopped all medications 3 months later, all symptoms had disappeared. On further investigation, spinal MRI revealed a Tarlov cyst. She has been in remission for three years. This case illustrates the co-occurrence of PHASA and PGAD and suggests a possible common pathophysiology shared between these two rare disorders.
