  We present a systematic search for extraplanar X-ray point sources around 19
late-type, highly inclined disk galaxies residing in the Virgo cluster, based
on archival Chandra observations reaching a source detection sensitivity of
$L\rm(0.5- 8~keV)\sim10^{38}\rm~erg~s^{-1}$. Based on the cumulative source
surface density distribution as a function of projected vertical distance from
the disk mid-plane, we identify a statistically significant ($\sim3.3\sigma$)
excess of $\sim20$ X-ray sources within a projected vertical off-disk distance
of $0.92'-2.5'$ ($\sim4.4-12\ \mathrm{kpc}$), the presence of which cannot be
explained by the bulk stellar content of the individual galaxies, nor by the
cosmic X-ray background. On the other hand, there is no significant evidence
for an excess of extraplanar X-ray sources in a comparison sample of field
late-type edge-on galaxies, for which Chandra observations reaching a similar
source detection sensitivity are available. We discuss possible origins for the
observed excess, which include low-mass X-ray binaries (LMXBs) associated with
globular clusters, supernova-kicked LMXBs, high-mass X-ray binaries born in
recent star formation induced by ram pressure stripping of the disk gas, as
well as a class of intra-cluster X-ray sources previously identified around
early-type member galaxies of Virgo. We find that none of these X-ray
populations can naturally dominate the observed extraplanar excess, although
supernova-kicked LMXBs and the effect of ram pressure are most likely relevant
