Whole-body 18F-FDG PET/CT scan in a patient with Lymphoma taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the right palatine tonsil was full with increased FDG uptake (SUVmax = 5.9).
The laryngopharynx was normal in morphology and structure.
The bilateral parotid and submandibular glands had normal morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with slightly uneven density; punctate dense shadows were observed in the left lobe, but FDG uptake was normal.
Bilateral deep cervical interspace, submandibular, and submental lymph nodes were observed.
The largest was located in the right deep cervical interspace, with a short diameter of approximately 0.6 cm, showing increased FDG uptake (SUVmax = 3.9).
A nodule/patchy soft tissue density shadow was observed in the right anterior superior and middle mediastinum, with indistinct borders, measuring approximately 5.0*3.3*5.6 cm, showing increased FDG uptake (SUVmax = 4.4), and indistinct demarcation from the adjacent pericardium.
A slightly enlarged supraclavicular lymph node was observed on the left side, with a short diameter of approximately 0.8 cm, showing increased FDG uptake (SUVmax = 2.3).
A right hilar lymph node was observed, with a short diameter of approximately 1.0 cm, showing increased FDG uptake (SUVmax = 3.8).
Lung markings were clear bilaterally.
Several small solid nodules were observed in the lateral segment of the right middle lobe and the left lower lobe, the largest being approximately 0.3 cm in diameter, with no abnormal FDG uptake.
Scattered linear lesions were observed bilaterally, with no abnormal FDG uptake.
Partial pleural thickening was observed bilaterally, but there was no pleural effusion or pneumothorax.
No abnormalities were observed in the cardiac silhouette.
Calcification was observed in some arterial walls (including the coronary arteries).
No esophageal dilation, thickening, or masses were seen in the esophagus; FDG uptake was not increased.
No obvious masses or nodules were observed in either breast; FDG metabolism was not significantly abnormal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissures were not widened; liver density was unevenly decreased; FDG uptake was not abnormal.
The main portal vein showed no significant widening; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was not thickened; localized FDG uptake was not abnormal.
The pancreas was normal in shape; no significant abnormal density shadows were seen in the parenchyma; the main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The left kidney was smaller; several cystic lesions were present in the renal parenchyma, the largest being approximately 1.0 cm in diameter; FDG uptake was absent; the renal pelvis, calyces, and ureter were not widened; FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach was adequately filled, with slight thickening of the gastric wall in the antrum and mildly increased FDG uptake (SUVmax = 2.7).
Intestinal filling was unsatisfactory, with partial calcification of the colorectal segment accompanied by widespread increased FDG uptake (SUVmax = 16.1).
The uterus was normal in shape and size, with no abnormal density shadows and normal FDG uptake.
No obvious abnormalities were seen in the bilateral adnexa.
The bladder was poorly filled, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneum.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
Generalized bone density was decreased, the spinal alignment was normal, with some vertebral marginal osteophytes.
Internal fixation of the L4-5 vertebral bodies was underway.
Generalized skeletal FDG uptake was normal.
Bilateral lower extremities showed no abnormalities on contrast imaging.

Impression

1. a. Space-occupying lesions in the right anterior superior and middle mediastinum with increased FDG metabolism, suggestive of an invasive neoplastic lesion, possibly thymoma; please correlate with clinicopathology. b. Possible chronic lymphadenopathy in the left supraclavicular and right hilar regions; tumor infiltration to be ruled out; follow-up is recommended.

2. Chronic inflammatory nodules in both lungs; CT follow-up is recommended. A few post-inflammatory lesions in both lungs. Partial pleural thickening on both sides. Calcification of some arterial walls (including coronary arteries).

3. Uneven fatty liver; ultrasound follow-up is recommended. Bilateral renal cysts.

4. Post-schistosomiasis sequelae, possibly chronic inflammatory changes in the gastric antrum and part of the intestine; please correlate with endoscopy.

5. Osteoporosis, degenerative changes in the spine, post-lumbar spine surgery changes.

6. Uneven thyroid density, calcification in the left lobe; ultrasound follow-up is recommended.

7. Age-related brain, deep lacunar infarcts; please correlate with MRI. Right palatine tonsillitis. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
