[Extracellular inclusions in the tissue of the vascular plexus of the human brain (scanning electron microscopy of the psammoma bodies)].
Three-dimension psammoma bodies imaging was performed utilizing the scanning electron microscopy. Spheric psammoma bodies had fibers woven at different angles at their surface. The dense nucleus approximately 30 micron in diameter was positioned at their center. The data conform with the earlier offered hypotheses postulating the stromal cells of the choroid plexus to play an active part in these bodies formation, and regarding the whole process as a result of the organ mineral dystrophy.
