It would be more likely to be the exit point of a miniature black hole. The entry point would likely be a very small hole.*
I call these exit wounds; the physics is that the exiting hypervelocity thing sets up a shock wave moving matter out of the way, and it's the shock wave excavates the material in the hole. (Even a black hole does this; a decent sized one (say 10^10 kg) is very small, so not much matter would be eaten during a transit of the Earth. It does, however, pull matter towards it and its wake sets up an explosive shock wave that fractures and evacuates material.)
* A black hole the mass of the Sun would have a radius of ~ 3 km, so one the mass of the Earth is a few mm, and a likely primordial black hole, with a mass of maybe 10^10 kg, would have a radius of 10^-17 m, or well below the size of an atomic nucleus. Such a small black hole would not "eat" much in its passage through the Earth, which might take 20 - 40 seconds or so, because not much would actually hit it. It's gravitational wake, however, would be another matter. Such a primordial black hole would leave a tiny entrance wound, but a large exit wound.
