PET-CT 29/04: appearance of multiple areas of discrete opacity bilateral in pulmonary parenchyma, predominating in the base (SUVmax: 3.7-right base. The comparative analysis with a previous examination of 03/18/2020 shows: the degree of glycolytic hypermetabolism persists without significant variation associated with reduced dimensions, in heterogeneous tissue formation. The findings are compatible with uptake above mediastinal, but below or equal to uptake in the liver with nodal or extranodal sites with or without a residual mass indicating a non-progressive disease with a complete metabolic response to lymphoma treatment. The appearance of multiple areas of ground-glass opacities sparse by the bilateral pulmonary parenchyma, predominantly at the right base, suspicious for viral pneumonia
