Figure 3 Pheochromocytoma. USG (a) and CT abdomen (b) of a 14-year-old male patient with headache and hypertension demonstrate bilateral suprarenal masses (thick white arrows). On ultrasound, isoechoic to hypoechoic masses were seen adjacent to bilateral kidneys and in paraaortic region on left side. On CT, enhancing bilateral suprarenal masses were seen without any calcification. The left suprarenal mass showed heterogeneous contrast enhancement with evidence of necrosis within it. The left paraaortic mass showed homogeneous contrast enhancement. Urinary/plasma VMA was raised. H&E stained slide (c) shows polygonal tumor cells with moderate amount of granular eosinophillic cytoplasm. CT, computed tomography; H & E, haematoxylin & eosin; NCCT, noncontrast computed tomography; USG, ultrasonography; VMA, vanillylmandelic acid.
