"As is the case with the rest of the pineal gland, pineocytomas do not have a well-formed blood brain barrier and as such enhance vividly with contrast 6."

"Under light microscopy, pineocytomas are composed of small cells similar in appearance to normal pinealocytes, arranged in sheets; pineocytomatous pseudorosettes are characteristic and not seen in normal pineal gland tissue 9."
