	Email Address:	Viewable for logged on visitors (Log on)
	Age:	N/A
	Gender:	N/A
	Region-Organ:	Head-Other or unknown
	Most likely etiology:	neoplastic
	History:	Symptoms, which are mostly seen as an overactivity of the anterior pituitary. (I.e. large size, breast secretions, hypergonadism, hyperthyroidism, and others).
	Pathomorphology or Pathophysiology of this disease :	Adenomas are more frequently found in healthy children and adolescents without any hormone defects (= incidentalomas). Localized adenomas are rarer in hyperprolactemia; in IGF/BP3 it is higher. According to definition, macroadenomas are larger than 10 mm.
	Radiological findings:	<- view MRI 1 MRI 1: T1 native - Coronal Mostly hypointense or not well-marcated (isointense) <- view MRI 2 MRI 2: T1 with contrast - Coronal After contrast application in the early phase, there is a good hypointense demarcation of the microadenoma, therefore dynamic contrast sequences are of value. <- view MRI 3 MRI 3: T1 with contrast- Sagittal Posterior pituitary is hyperintense (Signal intensity is dependent on the functionality of the posterior pituitary), the anterior pituitary shows some signal intensity. <- view MRI 4 MRI 4: T2 - Coronal Rarely hypertense in T2 weighted images. Most often T2-weighted images show no advantage. One-sided lowering of the sella floor, or lifting of the sella upper wall, asymmetry and/or elongation of the pituitary stalk.
	Diagnosis confirmation:	Total constellation (Consens)
	Which DD would be also possible with the radiological findings:	Tumor, Hemorrhage, Cyst
	Course / Prognosis / Frequency / Other :	N/A
	Comments of the author about the case:	In autopsy reports/statistics, there are 3-27% incidentalomas reported. Probably they are diagnosed as microadenomas in MRI.
