When one pupil is dilated when compared to the other is some sort of mass pressing on the oculomotor nerve; recall that parasympathetic tone is carried with the Oculomotor nerve to the pupil; the parasympathetic response in the pupil is constriction; if a mass is pressing on the nerve, the fibers are irritated and one would expect sympathetic tone to prevail causing dilation of that particular pupil. Among mass effect from a tumor, consider a berry anyeurism forming at the bifurcation of the posterior communicating artery from the posterior cerebral artery... the oculomotor nerve travels right between the PCA and the superior cerebellar artery... If you're suspecting a CN-III issue, also look for other signs such as muscle weakness of the medial rectus, etc...
