Itis possible that the smaller cavities are the result of ananalogous expansion of the periganglionic (pericellular)spaces. The view that all these gaps are analogous intheir origin to retention cysts, is supported by the factthat sclerosis, thickening, infiltration, and adhesion of thepia, all factors which are apt to prove obstructive to thelymph out-flow, if not to the venous return circulation, are Fig. 2.
