  A hypersurface $M$ in $\mathbb{R}^n$, $n \geq 4$, has central ovaloid
property if $M$ intersects some hyperplane transversally along an ovaloid and
every such ovaloid on $M$ has central symmetry. We show that a complete,
connected, smooth hypersurface with central ovaloid property must either be a
cylinder over a central ovaloid or else quadric.
