Patient 2. Upper row - before tuberculostatic therapy: high FDG uptake in several mediastinal and one right axillary (arrow) lymph nodes. Additionally, further lymph nodes with high FDG uptake, especially in the left paraaortal (arrow head) region. Lower row - 7 month follow up after initiation of tuberculostatic therapy: No FDG uptake in the right axillary lymph nodes and significant regression of FDG uptake of the paraaortal lymph nodes after therapy. All PET positive lymph nodes had a morphological correlate and showed a significant size reduction after therapy in contrast enhanced CT (not shown).
