"Often, the presentation is relatively indolent without overt features of infection 1. Symptoms include those from mass effect (e.g. bitemporal hemianopia and headaches), endocrinological dysfunction (e.g. loss of libido, polydipsia, polyuria, amenorrhoea) and only sometimes (~25%) infective symptoms (e.g. fevers and meningism) 1,2. As such pituitary abscesses are often not diagnosed pre-operatively but rather are thought to be the far more common pituitary adenoma that not infrequently demonstrate cystic/necrotic degenerative change."

"MRI is the modality of choice for evaluating a patient suspected of having a pituitary abscess. It will demonstrate features of an abscess; peripherally enhancing mass with central high T2 signal, high DWI signal and low ADC values. It should be noted, however, that macroadenomas with haemorrhagic change may have similar appearances."
