PET Scan readings - Pre- and Post-treatment

Andrea39

Here are the readings from my pet scans. Kindly let me know how do you find these results. (History: Right tonsil Hpv + cancer with lymph nodes involved)

Key excerpts from the report below: 

1. Previously noted enlarged right cervical lymph nodes have significantly decreased in size. For reference, right level II measures 1.0 cm (short axis) with the activity of 3.1 SUV (previously 2.4 cm, 9.2 SUV), right level III node measures 0.6 cm (short axis) with the activity of 3.0 SUV, previously (3.0 cm, 11.3 SUV).

2. There is a mild asymmetric increased uptake in right lingual and palatine tonsils with the activity of 4.7 and 4.1 SUV respectively (previously it was 9.2 SUV). Diffuse hypermetabolic soft tissue thickening with SUV of 5.4 is seen in the supraglottic region causing mild narrowing of the laryngeal lumen; it is asymmetrically more on the right side. Findings most likely due to post radiation changes. However, would recommend ENT consultation to rule out underlying disease process.

3. Previously noted small subcentimeter right inguinal nodes showing hypermetabolic activity are again seen. For reference, index node measures 0.8 cm with the activity of 3.3 SUV.

Conclusion: Interval reduction in the soft tissue thickening hypermetabolic activity involving the tonsillar regions with interval reduction in the size of right cervical nodes and resolution of left inguinal lymph nodes. Interval development of hypermetabolic soft tissue fullness in the supraglottic region is most likely due to post radiation changes, however, ENT consultation is advised to rule out the underlying recurrent disease. The small subcentimeter right inguinal lymph nodes are still metabolically active and most likely reactive.
