Acute porphyria, though rare, has well-known neurological sequelae. Vasospasm rarely complicates exacerbations of acute intermittent porphyria, but has not been previously reported in hereditary coproporphyria. We describe a porphyric crisis in a woman with previously undiagnosed hereditary coproporphyria (triggered by rifampicin), leading to vasospasm and stroke.
