The pineal gland and Rosenthal fibres.
115 pineal glands, collected from patients who died from various neurologic and visceral diseases, were studied. The Rosenthal fibres (RF) forming gliosis is consistently evident in the subependymal tissue around the gland, in the pineal recessus and in the intrapineal glial proliferation. In several instances the focal gliosis exhibited a central cystic degeneration. The RF-forming gliosis of the pineal gland appears independent of the basic diseases and of the process of atrophy and degeneration of the gland parenchyma. The embryonic development of the pineal gland could explain why the formation of RF may be considered a quasi-physiologic process of this region.
