Patchy increased FDG uptake in both shoulder periarthritis, SUVmax = 2.8.
No abnormalities observed on limb imaging.
Mediastinal blood pool SUVmax = 3.6, hepatic blood pool SUVmax = 4.6, used for Deauville score.

Impression

1. Post-lymphoma treatment, compared with our center's PET/CT examination on November 4, 2022: a. The gastric antrum wall is thicker, with increased FDG metabolism in some areas, similar to before, suggesting post-treatment changes. Some tumor activity remains to be ruled out; please combine clinical findings with a follow-up gastroscopy. b. Multiple lymph nodes are visible in both cervical, hilar, mediastinal, retroperitoneal, mesenteric, and bilateral inguinal regions. The hilar lymph nodes are larger than before, with increased FDG metabolism; the remaining lymph nodes are similar to before, suggesting possible reactive hyperplasia or inflammation. Follow-up is recommended. c. L2 vertebral compression fracture, pathological cause to be ruled out; possible post-injury changes in the L5 vertebral body, lymphoma infiltration to be ruled out. Follow-up is recommended for all of the above.

2. a. Interstitial lung changes with chronic inflammation and sequelae, chronic inflammatory nodules and plaques in both lungs, similar to previous findings; please follow up with CT scan. Bilateral breast hyperplasia with calcification. b. Post-coronary stent placement, partial arteriosclerosis (including coronary arteries), dilation of the ascending aorta; please consult a specialist.

3. Liver cyst, possible hemangioma in the left lobe of the liver; MRI examination if necessary. Gallstones, chronic cholecystitis. Left renal cyst. Left adrenal hyperplasia, similar to previous findings.

4. Cystic mass in the tail of the pancreas, FDG metabolism normal, similar to previous findings; cystadenoma to be ruled out; enhanced MRI follow-up recommended.

5. Increased FDG metabolism in some intestinal segments, considered physiological uptake or chronic inflammation. 6.a. Osteoporosis, scoliosis with degenerative changes. Old compression fractures of the T11, T12, and L4 vertebrae. L4/5 and L5/S1 intervertebral disc bulges. Old subcutaneous lesions in both buttocks. Bilateral frozen shoulder. b. Post-internal fixation of the right proximal femur fracture, changes following fractures of the right 7th, 8th, and 10th ribs and the left 10th rib.

6. Bilateral deep lacunar infarcts, white matter degeneration, senile encephalopathy. Left maxillary sinusitis.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
