Fig. 2From: Low apparent diffusion coefficient in an extracranial brain tumor: a case reportMagnetic resonance imaging from the preoperative examination (a–e) and 3 weeks after the operation (f). A mixed-signal mass (asterisk) was observed in the right cerebellopontine angle, presenting with solid and cystic components (white arrowhead) on T2-weighted coronal imaging (a). The solid component showed hypersignal on diffusion-weighted imaging (b) and significant hyposignal on the apparent diffusion coefficient map (c). After contrast injection, this mass was poorly enhanced (d). On the 3D-constructive interference in steady-state sequence (e), the VII/VIII cranial nerve complex (white arrow) was observed to be anteriorly displaced. The postoperative axial 3D-constructive interference in steady-state sequence (f) revealed a normal right cerebellar hemisphere (white curved arrow), and the VII/VIII cranial nerve complex (white arrow) returned to its expected locationBack to article page
