     Pediatric Radiology CasesMost likely etiology:

    neoplastic  

     
     Pediatric Radiology CasesHistory:

    Symptoms, which are mostly seen as an overactivity of the anterior pituitary. (I.e. large size, breast secretions, hypergonadism, hyperthyroidism, and others).  

     
     Pediatric Radiology CasesPathomorphology 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.  

     
     Pediatric Radiology CasesRadiological findings:


    MRI 1 <- view MRI 1

    MRI 1: T1 native - Coronal
    Mostly hypointense or not well-marcated (isointense)





    MRI 2 <- 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.





    MRI 3 <- 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.





    MRI 4 <- 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.



     

     
     Pediatric Radiology CasesDiagnosis confirmation:

    Total constellation (Consens)  

     
     Pediatric Radiology CasesWhich DD would be also possible with the radiological findings:

    Tumor, Hemorrhage, Cyst  

     
     Pediatric Radiology CasesCourse / Prognosis / Frequency / Other :

    N/A  

     
     Pediatric Radiology CasesComments of the author about the case:

    In autopsy reports/statistics, there are 3-27% incidentalomas reported. Probably they are diagnosed as microadenomas in MRI.
