I present five cases of acute onset hypoacusia (four unilateral and one bilateral), all of different physiopathological mechanisms and vascular territories, secondary to either arterial or venous causes. First case is a 39-year-old male with Left Middle Inferior Pontine Syndrome (Foville Syndrome) with associated Vertebro-Basilar Insufficiency (VBI) secondary to Spontaneous Vertebral Artery Dissection (SVAD) and secondary hypoacusia. Case two, is a 76-year-old female with right Anterior Inferior Cerebellar Artery (AICA) Syndrome generating a lateral pontine infarct with hypoacusia as an initial presentation. Case three, is a 77-year-old male presenting a left Superior Cerebellar Artery (SCA) infarct with hypoacusia as an initial presentation. Case four, a 79-year-old female patient presenting sudden onset bilateral hypoacusia secondary to Basilar Artery (BA) thrombosis. Finally, case five, is a 23-year-old post-partum female presenting a right Transverse Venous Sinus Thrombosis (CVST) presenting with acute hypoacusia as only clinical manifestation.
