Dark spots on x-rays mean there is some fluid there.
Fluid actually is radiopaque. Therefore, it blocks the x-rays from travelling through your lungs to the film and developing (darkening) that area. It is because of this that fluid, bones, and other structures actually appear white on an xray.
Dark spots can show up due to pockets of air (hyperinflation) or even a pneumothorax (popped/deflated lung.) It is also widely known in the medical field that xrays are drawn to spots of cancerous tissue. (This is why chemotherapy is so effective.) Due to this, it could also be a cancerous tumor behind your lungs directing many of the xrays to one location, developing the film more in that area and showing up as a darker spot.
