Hypoglycemia and growth hormone deficiency. There is a small focus of T1 hyperintensity on the fat-suppressed images in the midline along the stalk of the pituitary with a relatively small posterior pituitary bright spot within the sella, compatible with partially ectopic posterior pituitary gland. There is no abnormal enlargement of the pituitary gland or focal lesion identified within the gland itself. There is apparent dilatation of the lateral and third ventricles. The fourth ventricle appears to be within normal limits. No obstructing lesion is identified. The corpus callosum appears formed, but abnormally thin. Furthermore, there is diffuse paucity of white matter bulk in the cerebral hemispheres. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mild mucosal thickening in the paranasal sinuses. The skull base appears to be somewhat dysplastic.
1. Findings compatible with partially ectopic posterior pituitary gland.2. Diffuse white matter deficiency with ventriculomegaly, which may be related to growth hormone deficiency. Further evaluation with a dedicated brain MRI may be useful.3. The skull base appears to be somewhat dysplastic, which may also be related to growth hormone deficiency.
