"intracochlear schwannoma: tumour confined to the cochlear (see: intracochlear schwannoma)"
"T1: slightly hyperintense to normal intralabyrinthine fluid"
"T2: hypointense to normal intralabyrinthine fluid"
"T1 C+ (Gd): vivid enhancement"
"multifocal: for tumours located in multiple locations either on the same side or bilaterally. Each tumour should be described."
"The term inner ear schwannoma is preferred over intralabyrinthine schwannoma on account of the term "labyrinth" sometimes being used to denote only the vestibular labyrinth 4."

"transfundal without modiolar involvement: intravestibular tumours with growth extending through the macula cribrosa into the internal acoustic meatus (formerly known as transmacular intravestibular schwannomas) 2,4"
"transfundal with modiolar involvement: tumours with growth extending through the modiolus into the internal acoustic meatus (formerly known as transmodiolar intracochlear schwannomas) 2,4"
"A tumour can extend from the inner ear into the middle ear through the semicircular canals of the stapes footplate. These tumours have been termed variably transotic, although in this classification system, as this occurrence does not add management complexity it has been deemed an unnecessary term 4. Nonetheless, the presence of such extension should be identified and described in reports."
Expected headings
"Classification"
"MRI is the modality of choice for assessment of potential intralabyrinthine schwannoma as it allows not only identification but also localisation of the tumour within the labyrinth. Adequate assessment requires high-resolution, high-contrast T2-weighted images (e.g. FIESTA or CISS)."
