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: Patchy low-density shadows with clear borders were seen in the right basal ganglia, with absent FDG uptake.
No abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was seen, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was seen, and FDG uptake was not abnormal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
Post-thyroidectomy, no abnormal FDG metabolism was observed in the surgical area.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Scattered patchy opacities were observed in the left lung, with increased FDG metabolism (SUVmax = 3.9).
A few scattered punctate and linear opacities were also observed in both lungs, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was observed.
Irregular thickening of the lower thoracic esophagus wall, approximately 5.9 cm in length, with increased FDG metabolism (SUVmax = 18.5).
Several enlarged lymph nodes were observed in the mediastinum, paratracheal region, and left supraclavicular fossa, the largest with a short diameter of approximately 1.5 cm, with increased FDG metabolism (SUVmax = 16.7).
Bilateral breasts are normal, and FDG metabolism is normal.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure.
A low-density nodule, approximately 1.7 cm in length, is seen adjacent to the falciform ligament in the left medial lobe of the liver; FDG metabolism is normal.
No other abnormal density shadows or FDG uptake are observed in the remaining liver parenchyma.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder's shape and size are normal, the gallbladder wall is not thickened, and local FDG uptake is normal.
The pancreas is normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct is not widened, and FDG uptake is normal.
A spleen-like nodule, approximately 0.8 cm in length, is seen adjacent to the spleen; FDG metabolism is normal.
The spleen's shape, size, density, and FDG uptake are normal.
A cystic lesion, approximately 0.7 cm in long diameter, was observed in the right kidney, with absent FDG uptake.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was not significantly abnormal.
The left adrenal gland was slightly enlarged, with increased FDG uptake (SUVmax = 2.4).
No obvious abnormalities were observed on the right adrenal gland.
The stomach was poorly distended, with no obvious thickening of the stomach wall and no obvious abnormalities in FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The uterus was of normal shape, with no abnormal FDG metabolism.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. A mass in the lower thoracic esophagus with elevated FDG metabolism, suggestive of esophageal cancer. Metastasis to the mediastinal paratracheal and left supraclavicular lymph nodes.

2. Left lung infection. Minor chronic inflammation and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Post-thyroidectomy changes.

4. Low-density nodule in the left medial lobe of the liver, normal FDG metabolism, suggestive of hemangioma or cyst. A pseudo-lesion near the falciform ligament needs further investigation; enhanced MRI is recommended.

5. Accessory spleen. Right renal cyst. Left adrenal hyperplasia.

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

7. Softening lesions in the right basal ganglia region, suggestive of age-related brain changes.

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.
