Neurosecretory bodies within the median eminence in association with pituitary tumours.

During necropsy the pituitary stalk is usually deliberately divided and the median eminence is separated from the posterior pituitary. In a series of 133 necropsies the brain was removed in a manner that preserved the integrity of the neurohypophysis and allowed histological examination of the entire neurohypophysis and the juxtaposed adenohypophysis. Neurosecretory bodies were found within the neurohypophysis in 2 patients,and in both microadenomas were found within the adenohypophysis. 2 other patients had larger tumours within the adenohypophysis but had no abnormalities within the neurohypophysis.
