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 scan showed: Multiple lymph nodes in the bilateral deep cervical spaces, submandibular region, bilateral posterior cervical triangles, and bilateral supraclavicular fossae were observed after lymphoma treatment.
The largest was located in the left deep cervical space, measuring approximately 0.7*1.1cm, with increased FDG uptake (SUVmax=2.8).
Multiple lymph nodes in the bilateral axillae were also observed, with the largest located in the right axilla, measuring approximately 0.9*1.9cm, with increased FDG uptake (SUVmax=9.5).
Multiple lymph nodes in the hepatogastric space, bilateral iliac vessels, bilateral pelvic walls, and bilateral inguinal regions were also observed, with the largest located in the right inguinal region, measuring approximately 1.8*0.9cm, with increased FDG uptake (SUVmax=7.3).
No abnormal density shadows were observed in the nasal cavity, and FDG metabolism was normal.
The brain morphology and structure were normal, with no abnormal density shadows observed in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
Both 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, and FDG metabolism was normal.
The palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology or structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, but its density was somewhat uneven, and FDG uptake was increased (SUVmax = 3.5).
Lung markings were clear bilaterally.
Multiple calcifications and linear lesions were observed in the upper lobes of both lungs and the posterior segment of the right lower lobe, most prominent in the apex of both lungs, with no abnormalities in FDG metabolism.
Scattered small speckled and linear lesions were observed in both lungs, with no abnormalities in FDG uptake.
No thickening of the pleura was observed bilaterally, and there was no effusion or pneumothorax in either pleural cavity.
The cardiac silhouette was normal.
The esophagus showed no dilation, but increased FDG uptake in the lower segment wall (SUVmax = 4.2).
Both breasts showed dense glandular tissue with no obvious masses or nodules; FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall; local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach is adequately full, with slight thickening of the gastric wall in the antrum and mildly increased FDG uptake (SUVmax = 2.4).
Intestinal fullness is unsatisfactory; no masses are observed locally, but FDG uptake is increased in some intestinal segments (SUVmax = 13.2).
The uterus is normal in shape and size, with no abnormal density shadows; FDG uptake is increased in the endometrial area (SUVmax = 5.5).
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly full, with no obvious positive stones.
The spinal alignment is normal, with mild osteophyte formation at the margins of some vertebrae.
FDG uptake of the entire skeleton is normal.
The mediastinal blood pool SUVmax = 1.8, and the liver SUVmax = 2.5, used for the Deauville score.

Impression

1. Post-lymphoma treatment: a. Multiple lymph nodes throughout the body showing increased FDG metabolism, suggestive of lymphoma infiltration; comparison with previous imaging data and follow-up are recommended. b. No space-occupying lesions were seen in the nasal cavity; FDG metabolism was normal, suggesting suppressed tumor activity.

2. Old tuberculosis in both lungs; CT follow-up is recommended. Scattered post-inflammatory lesions in both lungs. Bilateral breast hyperplasia.

3. Physiological uptake in the endometrial area is possible; please combine with specialist examination.

4. Chronic inflammatory changes in the lower esophagus, gastric antrum, and part of the intestine; please combine with endoscopic follow-up.

5. Mild osteophyte formation in the spine.

6. Uneven thyroid density and increased FDG metabolism suggest possible inflammation; ultrasound follow-up is recommended.

7. No obvious abnormalities were seen on cranial scintigraphy.

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.
