bilateral vestibular schwannoma
Neurofibromatosis
type 2: proptosis as the initial presentation. T1WI axial image showing bilateral cerebellopontine angle (CPA) hypointense masses (s). Another left sphenoid wing, extraaxial in the medial temporal lobe, T1 isointense mass (m) with intraorbital extraconal extension (e) with left globe proptosis.
Neurofibromatosis
type 2: proptosis as the initial presentation. Note the intraorbital extension of meningioma (e) along the lateral wall of the orbit. Optic nerve and its sheath appear normal.
Neurofibromatosis
type 2: proptosis as the initial presentation. On GRE, blooming black dots in schwannoma (encircled) suggest microscopic haemorrhages.
Neurofibromatosis
type 2: proptosis as the initial presentation. Optic nerve and sheath are normal (arrow). m = meningioma, s = vestibular schwannoma. e = intraorbital extension of meningioma.
Neurofibromatosis
type 2: proptosis as the initial presentation. Note the intense enhancement of schwannomas (s). Meningioma (m) also shows avid enhancement but slightly less as compared to schwannoma. Meningioma encased left internal carotid artery (thick arrow) and middle cerebral artery (thin arrow).
Neurofibromatosis
type 2: proptosis as the initial presentation. T2WI showing heterogenously hyperintense bilateral CPA masses (s) causing widening of internal acoustic meatuses with intracanalicular extension(*). Meningioma (m) is isointense on T2 with intraorbital extension (e).
Neurofibromatosis
type 2: proptosis as the initial presentation. Intense enhancement of bilateral CPA schwannomas and left sphenoid wing meningioma. Note meningioma extending to intraorbital extraconal space.

Neurofibromatosis
type 2: proptosis as the initial presentation. Intense enhancement of bilateral CPA schwannomas (s) and left sphenoid wing meningioma (m). Note meningioma extending to intraorbital extraconal space (e).
Neurofibromatosis
type 2: proptosis as the initial presentation. Enhancement of meningioma is slightly less than schwannoma.
