Sensorineural deafness sensorineural hearing loss (SNHL) has been rarely reported in patients following both general and regional anesthesia. It can be conductive or sensorineural, unilateral or bilateral, and transient or permanent. There are a number of potential etiologies described for postoperative SNHL however its occurrence as a prodrome of stroke has never been described before. Here, we report such a case. Our patient, after a 3 h-long laparoscopic surgery for common bile duct exploration, reported vertigo and sensorineural deafness after 4 h postoperatively. An otolaryngology examination revealed bilateral dull tympanic membrane with bilateral profound sensorineural hypoacusis on pure tone audiometry. Computed tomography (CT) at this stage was not significant. However in the next 24 h, she developed features of posterior stroke, which was confirmed on magnetic resonance imaging (MRI). By this case report, we would like to highlight that though a rare entity, sudden vertigo followed by bilateral sensorineural deafness in the immediate postoperative period could be a warning sign of an impending brainstem or cerebellar infarction/stroke. An immediate MRI rather than a CT scan is better for diagnosis and further management of these patients.
