I run across a similiar abberations. On is internal lens flare caused by dust particles trapped inside the elements. It was a cheap camera & lens combination. I have also had static electricity do things to film. If the film is rewound too fast on certain "weather type" days static electricity will cause a strange effect. Dust in the film chamber will scratch trough a layer of film. I have seen problems caused by defective developing processes will cause scratches in the emulsion. That is just with film & developing it. No telling what can happen to scanners.
