Figure 1: Maximum intensity projection image (a) of the fluoro-2-deoxyglucose-positron emission tomography–computed tomography of a patient with adrenal lesion suspicious of adrenocortical carcinoma shows an area of abnormal tracer activity in the left hypochondrium (black arrow) which on the transaxial contrast-enhanced computed tomography (b) and fused positron emission tomography–computed tomography (c) images localized to a heterogeneously enhancing lesion in the left adrenal gland with fluoro-2-deoxyglucose avidity significantly higher than the liver suggesting a malignant lesion (white arrow). The standardized uptake value-peak and TLRpeak of the lesion were 12.2 and 11.1, respectively. The final histopathological diagnosis was adrenocortical carcinoma. Another patient with a similar left adrenal lesion underwent fluoro-2-deoxyglucose-positron emission tomography–computed tomography which showed a low-grade tracer avid lesion in the left adrenal which is seen on the maximum intensity projection (d, black arrow), transaxial contrast-enhanced computed tomography (e), and fused positron emission tomography–computed tomography images (f). The lesion was diagnosed on positron emission tomography–computed tomography as benign as the fluoro-2-deoxyglucose avidity was comparable to the liver fluoro-2-deoxyglucose activity on the transaxial fused positron emission tomography–computed tomography (f, white arrow). The standardized uptake value-peak and TLRpeak of the lesion were 4.8 and 1.5, respectively, which were suggestive of a benign lesion. The final histopathological diagnosis was adrenal adenoma
