[Drug-induced reversible cerebral vasoconstriction syndrome : Ustekinumab as possible trigger?] / Medikamenteninduziertes reversibles zerebrales Vasokonstriktionssyndrom : Ustekinumab als möglicher Auslöser?

The reversible cerebral vasoconstriction syndrome (RCVS) is a common cause of thunderclap headache. Many trigger factors, such as the intake of vasoactive and less commonly immunosuppressive medication have previously been described. This article reports the first case of the occurrence of RCVS after the intake of ustekinumab in a female patient with a history of Crohn's disease.
