Abstract

We present a case of a female patient with reversible cerebral vasoconstriction syndrome (RCVS) arising after receiving subcutaneous injection of human placenta extract. A 44-year-old woman started taking human placenta extract with the aim of improving her menopausal symptoms, fatigue, and beauty. However, 18 days after taking human placenta extract, she had three episodes of thunderclap headache. Repeated cranial CT did not show subarachnoid hemorrhage; CSF examination showed neither xanthochromia nor inflammation. Brain diffusion weighted and FLAIR images were normal. However, magnetic resonance angiography showed multifocal segmental stenosis of the right middle cerebral artery and bilateral anterior cerebral arteries. Follow-up angiography, which performed 12 days after the oncet of thunderclap headache, revealed almost normalized flow in all cerebral arteries; we made a diagnosis of RCVS. She has had no symptoms and signs since the third attack of headache. The only identified etiologic factor was subcutaneous injection of human placenta extract started 18 days prior to onset. This is the first report of RCVS triggered by human placenta extract.<br>
