Solitary Sclerotic Fibroma of Right Cerebellopontine Angle

Sclerotic fibroma (storiform collagenoma) is a fibrotic tumor that occurs mainly in patients with Cowden syndrome, but it can also occur in isolation, as detailed in previous reports. Here we present a case of a solitary sclerotic fibroma in cerebellopontine angle. Brain magnetic resonance imaging revealed a lesion showing hypointense signal on both T1 and T2. The lesion was not enhanced after administering gadolinium. The tumor was removed integrally by surgery.
