Acute intermittent porphyria with atypical neuropathy

The patient we have described had lower extremity numbness, paresthesias, constipation, urinary retention, and sexual dysfunction. Laboratory evaluation confirmed a diagnosis of acute intermittent porphyria (AIP). Vitamin B6 and glucose therapy initiated resolution of symptoms. The sensory neuropathy described here is unusual, and we believe sexual dysfunction is a previously unreported manifestation of AIP.
