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: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Mild widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
Thickening of the ethmoid sinus mucosa was observed bilaterally, but not in the remaining paranasal sinuses; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and 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, with slightly uneven density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed bilaterally in the deep cervical spaces, submandibular region, or submental region.
Both lungs show clear lung markings.
A ground-glass nodule in the apical segment of the right upper lobe, approximately 0.6 cm in long diameter, with a maximum CT value of -619 HU, shows no abnormal FDG uptake.
Small solid nodules are present in the apical segment of the right upper lobe and the medial segment of the right middle lobe, the largest being approximately 0.3 cm in diameter; no abnormal FDG uptake was observed.
Irregular patchy shadows are present in the inferior lingular segment of the left upper lobe and the subpleural region of the left lower lobe; the latter is larger and contains calcifications with indistinct borders; FDG uptake is slightly increased (SUVmax = 2.9).
A few scattered patchy and linear lesions are present in both lungs; FDG uptake is increased (SUVmax = 3.9).
The left pleura shows thickening and adhesions; FDG uptake is increased (SUVmax = 3.1); a small amount of pleural effusion is present on the left side.
No significantly enlarged lymph nodes are seen in the bilateral hilum and mediastinum.
The mediastinum is deviated to the left; the cardiac silhouette is normal.
The cardiac chamber density is slightly lower than that of the myocardium; the pericardium is slightly thickened; and some arterial walls show calcification (including the coronary arteries).
The esophagus showed no dilation, but increased FDG uptake in the lower segment wall (SUVmax = 7.5).
Both breasts exhibited dense glandular tissue and multiple calcifications, with no significant abnormalities in FDG metabolism.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and slightly decreased liver density; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormalities in FDG uptake.
Following treatment for splenic lymphoma, the spleen showed no abnormalities in shape, size, density, or FDG uptake.
A soft tissue density nodule at the splenic hilum, approximately 1.0 cm in diameter, showed no abnormalities in FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no significant abnormalities in FDG uptake.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax = 3.7), while the right adrenal gland shows no obvious abnormalities on contrast imaging.
The stomach is adequately filled, with no thickening of the gastric wall and no abnormal FDG uptake.
Intestinal filling is unsatisfactory; no local masses are seen, but continuous FDG uptake is observed in some intestinal segments (SUVmax = 18.4).
The uterus is normal in shape and size, with no abnormal density shadows and no abnormal FDG uptake.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneum.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
Generalized bone density is decreased, the spinal alignment is normal, and some vertebral body margins show osteophyte formation.
L4/5 and L5/S1 intervertebral disc bulges, with no abnormal FDG uptake.
Generalized skeletal FDG uptake is normal.
Bilateral shoulder periarticular FDG uptake is increased (SUVmax = 6.7).
The mediastinal blood pool SUVmax was 2.9, and the liver SUVmax was 4.5, used for the Deauville score.

Impression

1. a. After treatment for splenic lymphoma, no obvious space-occupying lesion was found in the spleen, and FDG metabolism was normal. Tumor activity is considered suppressed. It is recommended to compare previous imaging data and follow up. b. Left pleural thickening and adhesions, slightly increased FDG metabolism, and a small amount of pleural effusion on the left side suggest that tumor activity is likely largely suppressed. It is recommended to compare previous imaging data and, in conjunction with clinical findings, rule out residual tumor activity.

2. a. Irregular patchy lesions in the lower lingular segment of the left upper lobe and the subpleural region of the left lower lobe, accompanied by slightly increased FDG metabolism, suggest possible chronic inflammation or atelectasis. It is recommended to compare previous imaging data and follow up. b. Ground-glass nodules in the apical segment of the right upper lobe, with normal FDG metabolism, suggest inflammation or atypical adenomatous hyperplasia. Annual HRCT follow-up is recommended. c. Chronic inflammatory micronodules in the right lung. Chronic inflammation and post-inflammatory remnants in both lungs. Slight pericardial thickening, mild anemia changes, and partial calcification of arterial walls (including coronary arteries).

3. Bilateral breast hyperplasia and calcifications; ultrasound follow-up is recommended.

4. Mild fatty liver. Accessory spleen. Left adrenal hyperplasia.

5. Possible chronic inflammatory changes in the lower esophagus and part of the intestine; endoscopic follow-up is recommended.

6. Osteoporosis, degenerative changes in the spine, L4/5 and L5/S1 disc bulges. Bilateral frozen shoulder.

7. Uneven thyroid density; normal FDG metabolism; ultrasound follow-up is recommended.

8. Deep lacunar infarcts in the brain; mild age-related encephalopathy. Minor chronic inflammation of both ethmoid sinuses.

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.
