Abstract: If a properly infinite von Neumann algebra on a separable Hilbert space is approximately finite dimensional with respect to the $ \ast$-ultrastrong topology, that is, if any finite number of elements may be approximated $ \ast$-ultrastrongly by elements of a finite-dimensional sub $ \ast$-algebra, then the algebra may be expressed as the bicommutant of an increasing sequence of factors of type $ {{\text{I}}_{{2^n}}}$.
