Abstract
PURPOSE: To report a 16-year-old female patient with pituitary apoplexy in the setting of coronavirus disease 2019 (COVID-19) infection-related thrombocytopenia in the absence of preexisting pituitary macroadenoma. METHODS: The patient had been admitted because of respiratory complications of COVID-19 infection and developed thrombocytopenia, intense headache, and symptoms of cavernous sinus syndrome. RESULTS: Urgent magnetic resonance imaging of the brain depicted a pituitary apoplexy. CONCLUSION: This case indicated that thrombocytopenia due to COVID-19 could be a predisposing factor for pituitary apoplexy in the absence of underlying pituitary disease.
