Zahra Bajalan Social Determinants of Health Research Center, Qazvin University of Medical Sciences, Qazvin, Iran 2018 03 13 2018 07 22 Vestibular Schwannoma (VS) is a brain tumor arising from the internal auditory canal, growing towards the cerebellopontine angle. Diagnosis and management of these tumors during pregnancy may present a therapeutic challenge. Herein, we report a case, of a huge VS presented in pregnancy by nonspecific symptoms. Thus, despite increased intracranial pressure and its possibly dangerous sequela, the patient delivered full-term vaginally. Finally, three months after delivery, VS underwent retrosigmoid microsurgical removal. The postoperative period was uneventful, with total hearing loss in her left ear and, transient paralysis of the left seventh cranial nerve. Gynecologists and Obstetricians should consider brain tumors in the differential diagnosis of CNS symptoms in the prenatal period, if there are no pregnancyrelated etiologies to explain. https://crcp.tums.ac.ir/index.php/crcp/article/view/188 https://crcp.tums.ac.ir/index.php/crcp/article/download/188/282
