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, and resting, 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.
Both eyeballs were symmetrical, with no significant abnormalities.
Thickening of the left maxillary sinus mucosa, with an intact sinus wall.
Nasal septum deviation was observed, but no thickening of the nasopharyngeal wall was seen; 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 bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A right supraclavicular fossa lymph node was visualized, with a short diameter of approximately 0.9 cm, showing increased FDG uptake (SUVmax = 6.0).
Increased lung markings were observed bilaterally.
Several solid nodules with clear borders were present in the upper lobes of both lungs and the lower lobe of the right lung, the largest approximately 0.3 cm in diameter, with no abnormal FDG uptake.
Multiple air-filled cavities were observed in the upper lobes of both lungs, and a few scattered linear lesions were present bilaterally, with no abnormal FDG uptake.
Slight pleural thickening was observed bilaterally, without pleural effusion or pneumothorax.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
Two areas of irregular thickening of the esophageal wall with increased FDG uptake were observed in the mid-thoracic and lower-thoracic segments, with SUVmax = 29.3 and 29.5, respectively, affecting areas of 3.2*2.1*4.6cm and 3.6*3.3*4.9cm, respectively.
Lumen narrowing was observed, with involvement at the cardia.
Multiple lymph nodes were visible in the paraesophageal, paracardial, and hepatogastric spaces, the largest with a short diameter of approximately 0.9cm, showing increased FDG uptake (SUVmax = 16.0).
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and no abnormal FDG uptake.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with increased density within the gallbladder.
The gallbladder wall showed no thickening, and localized FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
High-density shadows are seen in the renal pelvis, calyces, ureters, and bladder, but FDG uptake is not significantly abnormal.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax = 3.2), while the right adrenal gland shows no obvious abnormalities on contrast.
The stomach is poorly filled, with thickening of the cardia, part of the gastric body, antrum, and adjacent duodenal walls, and increased FDG uptake (SUVmax = 6.0).
The intestines are poorly filled, with no obvious space-occupying lesions, and exhibit physiological uptake.
The prostate is full, with patchy dense shadows inside, but FDG uptake is not abnormally increased.
Bilateral testicular hydrocele with small amount of fluid.
No obvious fluid accumulation in the abdomen or pelvis.
Slight lumbar scoliosis, osteophyte formation at the margins of some vertebral bodies, mild anterior displacement of the L4 vertebral body, and L4/5 intervertebral disc bulge.
Systemic bone marrow FDG metabolism was normal.

Impression

1. Space-occupying lesions in the mid-thoracic and lower-thoracic segments of the esophagus with increased FDG metabolism, consistent with esophageal cancer based on pathology; multiple lymph node metastases in the paraesophageal, perigastric, hepatogastric, and right supraclavicular fossa.

2. Chronic inflammatory micronodules in both lungs; CT follow-up is recommended. Emphysema with bullae formation in both lungs. A few post-inflammatory lesions in both lungs. Slight pleural thickening bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Gallbladder sludge-like stones or contrast agent residue. Left adrenal hyperplasia. Contrast agent residue in the urinary tract. Benign prostatic hyperplasia with calcification. Small amount of hydrocele in both testes.

4. Chronic inflammatory changes or physiological changes in some gastric and duodenal walls; endoscopic follow-up is recommended.

5. Slight lumbar scoliosis, degenerative changes in the spine, mild anterior slippage of the L4 vertebral body. L4/5 intervertebral disc bulge.

6. Age-related brain changes. Chronic inflammation of the left 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.
