Predominantly extraaxial astroblastoma: imaging and proton MR spectroscopy features.
J. Jeffery Baka, Suresh C. Patel, Joseph R. Roebuck, David Hearshen · PubMed · 1993
The CT, angiographic, MR, and proton MR spectroscopy findings in a case of astroblastoma, a rare neoplasm of glial cell origin, are presented. Of particular interest is the predominantly extraaxial location of the tumor. CT and MR demonstrated a complex mass consisting of a solid nodule and a peripheral septated cystic component. The extraaxial nature of the mass was suggested on MR.
