Intermittent spontaneous CSF rhinorrhea exacerbated by hormonal fluctuations associated with menstrual cycles

Abstract

Key Clinical Message This case underscores the importance of recognizing the potential link between hormonal fluctuations during the menstrual cycle and idiopathic intracranial hypertension (IIH), which could lead to spontaneous cerebrospinal fluid (CSF) rhinorrhea. Eliciting a history of intermittent clear rhinorrhea with the onset of menstrual cycle if presenting with menstrual migraines could allow for a more prompt diagnosis and treatment of IIH and CSF leak. Early diagnosis and intervention are crucial to prevent serious complications.
