Whole-body 18F-FDG PET/CT scan in a patient with Esophageal Cancer 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: Brain morphology and structure were normal.
Multiple punctate low-density shadows were visible in the deep bilateral cerebral regions, with no significant abnormalities in FDG uptake.
Slight widening of the sulci, fissures, and cisterns was observed.
The bilateral ventricles were symmetrical, and there was no midline shift.
The bilateral eyeballs were symmetrical, with no significant abnormalities.
The right maxillary sinus mucosa was slightly thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
FDG uptake of the oropharynx and laryngopharynx was normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
FDG uptake was normal.
One pure ground-glass nodule was observed in the posterior segment of the left upper lobe and the apical segment of the right upper lobe, with relatively clear borders.
The larger nodule had a long diameter of approximately 0.3 cm.
Multiple solid nodules were also observed in both lungs, also with relatively clear borders.
The largest nodule had a long diameter of approximately 0.3 cm.
FDG uptake was normal in all these cases.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Calcification was observed in the walls of the aorta and coronary arteries.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appears normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the local area.
The pancreas appears normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen appears normal in shape, size, density, and FDG uptake.
A small splenic nodule is visible around the spleen, but no abnormal FDG uptake is observed.
A small cystic lesion with relatively clear borders and a long diameter of approximately 0.5 cm is visible in the right kidney, but no abnormal FDG uptake is observed.
The left kidney appears normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormal FDG uptake is observed.
Bilateral adrenal gland imaging shows no obvious abnormalities.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Thickening of the lower esophageal wall in the cardia region, involving the lesser curvature of the stomach, with increased FDG uptake, measuring approximately 2.6 1.5 cm, SUVmax = 9.2; increased FDG uptake in the gastric antrum and body, SUVmax = 2.3.
Several small lymph nodes are seen in the lesser omental bursa, the largest with a short diameter of approximately 0.3 cm, showing mild FDG uptake, SUVmax = 1.1.
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
A small amount of fluid density shadow is seen in the tunica vaginalis of both testes.
Slight scoliosis of the spine, osteophyte formation at the margins of some vertebral bodies, calcification of the nuchal ligament, slight anterior displacement of the L4 vertebral body, and bulging of the L4/5 and L5/S1 intervertebral discs, with no abnormal FDG uptake.
A low-density nodule with sclerosis at the margins was observed in the anterior superior part of the right femoral head, but no abnormal uptake was detected by FDG.

Impression

1. a. Mass in the lower esophagus-cardia region, with increased FDG uptake, suggestive of cancer; please confirm with pathology. b. Chronic gastritis; endoscopic follow-up recommended. Reactive hyperplasia of lesser omental sac lymph nodes.

2. a. Pure ground-glass nodules in the posterior segment of the left upper lobe and the apical segment of the right upper lobe, with no abnormal FDG uptake, suggestive of inflammatory nodules or atypical adenomatous hyperplasia; annual HRCT recommended. b. Multiple chronic inflammatory micronodules (solid) in both lungs. Partial calcification of the aorta and coronary artery walls.

3. Accessory spleen. Small cyst in the right kidney. Small amount of hydrocele in both testes.

4. Scoliosis with degenerative changes. Mild anterior slippage of the L4 vertebral body. L4/5 and L5/S1 intervertebral disc bulges. Right femoral head herniation fossa.

5. Bilateral deep lacunar infarcts, age-related brain changes. Minor inflammation of the right maxillary sinus.

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.
