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: The brain morphology and structure were normal, with no abnormal density shadows 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.
The eyeballs were symmetrical, with no significant abnormalities.
Slight thickening of the mucosa of the bilateral maxillary and ethmoid sinuses was observed, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, 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 abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
FDG metabolism was increased in the tongue and left vocal cord, with SUVmax = 4.2.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Solid micronodules, approximately 0.2-0.3 cm in long diameter, with clear borders, were observed in the right middle lobe and the anterior basal segment of the right lower lobe; FDG metabolism was normal.
A few speckled, calcified, and linear lesions were also observed in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The liver is normal in shape and size; the liver margins are smooth, and the hepatic fissure is not widened; multiple cystic lesions are observed within the liver, the largest with a long diameter of approximately 3.0 cm; FDG uptake is absent.
The main portal vein is not significantly widened; no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, with slight thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen is normal in shape, with punctate calcifications visible within, and no abnormalities in FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
No obvious abnormalities were observed in the bilateral adrenal glands upon imaging.
Irregular thickening of the esophageal wall in the lower thoracic segment (below the carina), affecting a length of approximately 5.1 cm, with increased FDG metabolism (SUVmax = 9.3).
Multiple enlarged lymph nodes were observed in the right upper mediastinum near the trachea, at the left thoracic inlet, on the lesser curvature of the stomach, and beside the left mesentery.
The largest was found in the former, measuring approximately 6.5 5.6 cm, with increased FDG metabolism (SUVmax = 11.5).
Poor gastric filling, with no significant thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Continuous increased FDG metabolism was observed in the descending colon, sigmoid colon, and rectum (SUVmax = 4.5).
The prostate gland was of normal size and shape, with punctate calcifications observed, but no abnormal FDG metabolism was observed.
The bladder was generally full, with no obvious positive stones.
No significant fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
There is localized decreased bone density in the right vertebral arch at T1, increased FDG metabolism, and SUVmax = 3.4.

Impression

1. a. Mass in the lower thoracic esophagus, with increased FDG metabolism, suggestive of esophageal cancer. Multiple lymph node metastases in the mediastinum, lesser curvature of the stomach, and left paramesentery. b. Decreased bone density in the right vertebral arch of T1, with increased FDG metabolism, metastasis to be ruled out; MRI recommended.

2. Chronic inflammatory nodules (solid) in the right middle lobe and anterior basal segment of the right lower lobe. A few chronic inflammations and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Liver cyst; splenic calcification.

4. Continuous increased FDG metabolism in the descending colon, sigmoid colon, and rectum, suggestive of inflammatory or physiological uptake; colonoscopy recommended.

5. Prostatic calcification.

6. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge.

7. Cranial scintigraphy showed no abnormalities. Mild chronic inflammation of the bilateral maxillary sinuses and bilateral ethmoid sinuses.

8. Increased FDG metabolism in the tongue and left vocal cord, suggesting possible inflammatory uptake; specialist examination is recommended.

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.
