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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: Multiple nodules and patchy soft tissue density shadows in both orbits, most prominent in the left orbit, with a maximum cross-sectional area of approximately 2.8*1.5cm, showing increased FDG uptake (SUVmax=4.3).
The left eyeball was slightly protruding.
Multiple enlarged lymph nodes were also observed in the bilateral parotid region, bilateral deep cervical space, submandibular region, submental region, bilateral posterior cervical triangle, and bilateral supraclavicular fossa.
The largest was located in the right submandibular region, measuring approximately 1.7*1.7cm, with increased FDG uptake (SUVmax=4.7).
Multiple lymph nodes were observed in the bilateral axillae, bilateral hilum, mediastinum (pretracheal, posterior to the vena cava, para-aortic arch, aortopulmonary window, and subcarinal), and right supradiaphragmatic region.
The largest was located in the right axilla, measuring approximately 3.4*1.0cm, with increased FDG uptake (SUVmax = 3.7).
Multiple lymph nodes were also observed in the retroperitoneum, bilateral iliac vessels, and bilateral inguinal regions.
The largest was located in the right inguinal region, measuring approximately 3.0*2.0cm, with increased FDG uptake (SUVmax = 5.2).
The brain morphology and structure were normal, with calcification of the falx cerebri.
No abnormal density shadows were observed in the brain parenchyma, and no significant abnormalities were seen in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The bilateral ventricles were symmetrical, and there was no midline shift.
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 uptake was normal.
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear bilaterally, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the submandibular glands bilaterally.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in shape and size, but its density was slightly uneven, and FDG uptake was normal.
The lung markings were clear bilaterally.
Multiple solid nodules were observed in the right lung and the upper lobe of the left lung, the largest being approximately 0.3 cm in diameter, with no abnormal FDG uptake.
A few scattered linear lesions were observed in both lungs, with no abnormal FDG uptake.
Calcifications were present in the hilum of both lungs.
No thickening of the pleura was observed bilaterally, and there was no effusion or pneumothorax bilaterally.
The cardiac silhouette was normal.
Some arteriosclerosis was observed.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Several cystic lesions were observed within the liver, the largest being approximately 1.2 cm in diameter.
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 and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen was slightly enlarged, but its density and FDG uptake were normal.
A soft tissue density nodule was observed adjacent to the spleen, approximately 1.5 cm in diameter, with no abnormalities in FDG uptake.
Both kidneys are normal in shape and size.
A dense nodule in the left renal calyx, approximately 1.2 cm in long diameter, and a small cystic lesion in the right renal parenchyma, approximately 0.9 cm in diameter, are observed.
FDG metabolism is normal.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is normal.
Bilateral adrenal gland imaging is normal.
The stomach is adequately filled, with a considerable amount of residual contents.
No significant thickening of the stomach wall is observed, and FDG uptake is normal.
Intestinal filling is poor, with no significant thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is normal in size and density, and FDG uptake is normal.
Calcification is present in the left testicular tunica vaginalis.
The bladder is poorly filled, with no obvious positive stones.
Overall muscle uptake is high.
The spinal alignment is normal, with some vertebral marginal osteophytes and multiple lumbar disc bulges.
Localized palisade-like changes were observed in the T3 vertebral body.
Small cystic shadows were seen in the bilateral femoral head and neck, with no abnormal FDG uptake.
No abnormalities were observed on imaging of the bilateral lower extremities.
Mediastinal blood pool SUVmax = 1.1, liver SUVmax = 2.5, used for Deauville score.

Impression

1. Bilateral orbital lesions with increased FDG metabolism; multiple enlarged lymph nodes throughout the body with increased FDG metabolism (see description for details). These findings are consistent with lymphoma infiltration; follow-up examination after treatment is recommended.

2. Chronic inflammatory micronodules in both lungs. A few post-inflammatory lesions in both lungs. Calcifications in both pulmonary hilum. Partial arteriosclerosis.

3. Liver cysts. Slightly enlarged spleen, accessory spleen. Left kidney stone, right kidney small cyst. Calcification of the tunica vaginalis in the left testis.

4. Degenerative changes in the spine, multiple lumbar disc herniations. T3 vertebral hemangioma. Bilateral femoral head-neck herniation fossa.

5. Calcification of the falx cerebri; 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.
