48 yr. old female[barely] My MRI in 2009, showed a small, intersellar arachnoid cyst. Maybe this was misdiagnosed because the are so rare? Read this on report, the Neurologist said it was normal and didn't mention a cyst.. MRI in 2012, shows empty sella,pituitary atrophy. Is it really "empty" or is this the enlarged cyst?
