Pituitary [[microadenoma]], its a [[pituitary neuroendocrine tumor]] less than 10 mm in diameter.

At the time of diagnosis, 90 % of [[prolactinoma]]s in women are [[microadenoma]]s, vs. 60 % for males probably due to gender-specific differences in symptoms resulting in an earlier presentation in females.

===== Follow-up recommendations ===== 

No [[consensus]] exists regarding follow-up [[recommendation]]s for suspected [[pituitary microadenoma]] in [[child]]ren. To address this knowledge gap, Borghammar et al. from [[Lund]] investigated the growth potential of pituitary solid and [[cyst]]ic lesions <10 mm in children and evaluated the accuracy of [[magnetic resonance imaging]] (MRI) measurements.

Non-functioning pituitary microadenoma in children has small size variations, often below the spatial resolution of the scanners. They suggest lesions <4 mm only for clinical follow-up, lesions 4-6 mm for [[MRI]] after 2 years, and ≥7 mm MRI after 1 and 3 years, with clinical follow-up in between. If no progression, further MRI should only be performed after new clinical symptoms or hormonal disturbances.
