Example of early pseudoprogression in a patient with malignant melanoma: (a) initial Positron Emission Tomography/Computer Tomography with ¹⁸F-Fluorodeoxyglucose; (b) first evaluation after four series of ipilimumab shows multiple new foci in the liver and the bones with highly increased LDH (lactate dehydrogenase); and (c) subsequent scans after completion of treatment showing complete disappearance of both new foci and the primary lesions.
