Nanosomia, therefore a tumor in the hypophysial region or a maldevelopment of the pituitary gland must be ruled out.

In addition, absence epilepsy and mental retardeation - therefore diagnostic imaging to rule out an intracerebral tumor or an intracranial anomaly.

MRI 1: T1-SE saggital before contrast media: Depiction of a round hyperintense structure in the course of the pituitary stalk.



<- view MRI

MRI 2: T1-SE saggital after contrast media: Depiction of a round hyperintense structure in the course of the pituitary stalk. The anterior pituitary shows a normal position and contrast media absorption.

MRI 3: T1-SE coronal before contrast media: Depiction of a round hyperintense structure in the course of the pituitary stalk.

MRI 3: T1-SE coronal after contrast media: Depiction of a round hyperintense structure in the course of the pituitary stalk. The anterior pituitary gland (adenohypophysis) shows a normal position and contrast media absorption.
 

Imaging including endoscopy  

N/A  

The diagnoses of a pituitary infantilism was made based on the STH deficiency shown in laboratory findings.
For other symptoms (epilepsy, mental retardation), there were no imaging correlations as to the cause of such.
