|Patient: 8 year old male|
|History: 8 year old male with history of precocious puberty.|
Bone age study (performed when the patient was eight years old) demonstrates advanced bone age, greater than 9 standard deviations above the mean.
CT head (performed when the patient was two years old) demonstrates a minimally heterogeneous suprasellar mass with absence of calcifications.
MR Brain demonstrates a mass immediately inferior to the optic chiasm, continuous with the hypothalamus and mammillary bodies. This lesion is somewhat heterogeneous in appearance, slightly hypointense on T1- and slightly hyperintense on T2-weighted images, without evidence of contrast enhancement.
