spon·gi·o·blas·to·ma
(spŭn'jē-ō-blas-tō'mă),1. A glioma consisting of cells (elongated, spindle-shaped, and sometimes pleomorphic, with one or two fibrillary processes) that resemble the embryonic spongioblasts, occurring normally around the neural canal of the human embryo; it grows relatively slowly, usually originating in the brainstem, optic chiasm, or infundibulum; infiltrates adjacent structures or causes compression of the third and fourth ventricles. Spongioblastomas were formerly subclassified as spongioblastoma polare and spongioblastoma unipolare.
2. Obsolete term for glioblastoma multiforme.
