case_images: The patient had an insulin-like growth factor-1 (IGF-1) level of 182 and a serum growth hormone (GH) level of 7.2 following stimulation with L-3,4-dihydroxyphenylalanine (L-DOPA; upper and lower limits 5 ng/ml and 10 ng/ml, respectively.) Imaging revealed a large sellar enhancing lesion with lateral extension [Figure 1].

case_images: His growth trajectory had jumped several percentiles in this range, both in height and weight (Refer to Figure 2).
case_images: Non-functioning adenoma and recurrent, functioning adenoma. (a) Histological examination from the first resection showed sheets of a uniform population of neoplastic cells with loss of the normal adenohypophysis architecture, x200. (b) Several cells stained positive for GH immunohistochemistry (sparse granulation), 200x. Second resection after 9 years showed similar histological features HandE, x200 (c) and a more diffuse positivity for GH immunohistochemistry (dense granulation), x200 (d)
