11-year-old female with: sexual precocity on Lupron and GH. Evaluate for pituitary abnormality. MRI Brain:There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a centrally T2 hyperintense focus with marginal FLAIR hyperintense signal along the posterior right basal ganglia, along the anterior commissure, in the expected location of a prominent perivascular space. The brain parenchyma otherwise appears unremarkable. There is no evidence of abnormal enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is a small left maxillary sinus mucus retention cyst.MRI Pituitary:Dedicated images through the sella demonstrate a normal height of the pituitary gland. There is diffuse heterogeneous enhancement pattern involving the pituitary gland which can be expected for this age group. No mass is seen within the pituitary gland. There is minimal deviation of the pituitary stalk to the right which is most likely a normal variant. The suprasellar cistern, optic chiasm, cavernous sinuses and intracranial portions of the optic nerves appear unremarkable.
Brain parenchyma and pituitary gland are without abnormalities.
