Discrepant D scoring of the right supraclavicular region.
Case 63. a) Tumour involvement before treatment. b) Residual mass in this region after two cycles of OEPA. c) and d) slightly enhanced FDG uptake above background in this area. Interpretation might be complicated by a slightly enhanced FDG uptake symmetrically in the left supraclavicular area which, however, is in the surrounding of a catheter and by the inhomogeneous uptake in the mediastinum. Deauville score of the readers R1-5, respectively: 1-1-3-1-2. Courtesy Dept. Nuclear Medicine, Karolinska University Hospital, Stockholm, Sweden.

Residual uptake in the mediastinum vs. thymus.
Case 12: a) Lymphoma involvement of the upper and middle mediastinum including the thymus before treatment. b) and c) very slightly enhanced uptake as compared to the mediastinum after two cycles ChT. The interpretation might be complicated by the difficult decision whether this finding implies residual tumor uptake or physiological but inhomogeneous uptake in the thymus. Deauville score of the readers R1-5, respectively: 1-1-3-3-3. Courtesy Dept. Nuclear Medicine, Blackrock Clinic, Dublin, Ireland.

Discrepant D scoring of the neck region.
Case 44: a) Lymphoma involvement at both sides of the neck before treatment. b) and c) residual lymph node on the right neck with slightly enhanced FDG uptake after to cycles ChT. d) The residual uptake is less than in the liver, but it is difficult to decide if it is above or below the MBP uptake.

Discrepant D scoring of the mediastinum.
Case 39: a) extensive lymphoma involvement of the left side of the upper mediastinum before treatment. b) residual mass after two cycles ChT. c) highest residual FDG uptake in the dorsal part of the residuum. D) It is difficult to decide if this highest FDG uptake is above or below the liver uptake. The interpretation is complicated by the small size of the hottest part of the residuum. Deauville score of the readers R1-5, respectively: 3-3-4-4-4. Courtesy M. Reinhardt, Dept. Nuclear Medicine, Pius-Hospital, Oldenburg, Germany.

Discrepant D scoring of the right supraclavicular region.
Case 2.: a) extensive lymphoma involvement including the right supraclavicular region before treatment. b—d) enhanced FDG uptake in a right supraclavicular node clearly exceeding that of the mediastinum. It is difficult to decide if the nodal uptake is higher or less than the liver uptake. Deauville score of the readers R1-5 for the supraclavicular region, respectively: 3-4-3-3-4. Courtesy Dept.
