You have a few options.
You can try CASTp (either the web service or the PyMOL plugin). I think the .pocinfo file contains information about volumes.
You could also use Voidoo (http://xray.bmc.uu.se/usf/voidoo_man.html). In the distribution, there is a script (cavity.csh) can be used to used to run voidoo to find cavities. The resulting log files have information about volumes. To visualize the cavities, the resulting .ezd files have to bee converted to .ccp4 with mapman.
Hope this helps,
