Ancient schwannoma

Ancient schwannomas are long-standing, benign (WHO grade I) slow growing schwannomas with advanced degeneration. These can have calcification, hyalinization, and cystic cavitation that can be identified on imaging. The term “ancient” has been traditionally used to describe schwannomas showing degenerative changes and diffuse hypocellular areas 1-3.

Although microscopically these tumours can have nuclear pleomorphism they should not be misinterpreted as being malignant 4
