Enlargement of the vestibular aqueduct at cone-beam CT: ELST or EVA?

Abstract

The radiological diagnosis of enlarged vestibular aqueduct (EVA) can be challenging. Pathologies like the EVA and early stage endolymphatic sac tumor (ELST) can be difficult to differentiate as clinical characteristics are similar and these pathologies are rare. The cone beam CT (CBCT) is a new imaging technique with low radiation dose and high-resolution power that can be used to study patients affected by EVA or ELST. The present paper will take into account the imaging features that can help in distinguishing the above-mentioned pathologies when studied by mean of CBCT.
