• A vascular loop in the internal auditory canal was observed in 18-20% of the patients in this study; whether a loop can be responsible for a compressive syndrome is still unclear in particular referred to the vestibulocochlear nerve. • Compression by a loop on the facial nerve causes hemifacial spasm; compression by a loop on the cochlear or vestibular nerve may cause audio-vestibular symptoms. • In patients with a loop, the loop calibre, the loop position, and the number of loop-nerve(s) assessed via the multiplanar MRI reconstruction technique may help assess whether the patient will manifest audio-vestibular symptoms or hemifacial spasm.
