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 punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
The left lens was located posteriorly to the eyeball; no obvious abnormalities were seen in the right eye.
The bilateral maxillary sinus mucosa was thickened, containing multiple cystic shadows; the remaining paranasal sinuses showed no thickening, and the sinus walls were intact.
The nasal septum was deviated; the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx appear normal in morphology and structure.
The thyroid gland is normal in shape and size, but its density is somewhat uneven; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Increased lung markings are present bilaterally, with multiple solid nodules in both lungs, with clear borders; the largest is approximately 0.4 cm in diameter.
FDG uptake is normal.
Multiple air-filled cavities are present bilaterally, along with scattered linear lesions; FDG uptake is normal.
The pleura is thickened bilaterally, but there is no pleural effusion or pneumothorax.
Multiple lymph nodes are seen in the bilateral hilar regions, pretracheal spaces, para-aortic arch, aortopulmonary window, and below the carina; some are calcified, with the largest having a short diameter of approximately 0.9 cm.
FDG uptake is normal.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
Postoperative esophageal tumor surgery: No obvious space-occupying lesions were observed in the esophageal wall, and FDG metabolism was normal.
Liver morphology and size were normal; liver margins were smooth; hepatic fissures were not widened; plain CT scan showed no obvious abnormal density shadows in the liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
Gallbladder morphology and size were normal; gallbladder wall was thickened; local FDG uptake was normal.
Pancreas morphology was normal; no obvious abnormal density shadows were observed in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys morphology and size were normal; no obvious abnormal density shadows were observed in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
The stomach was adequately full, with a significant amount of residual contents; the stomach wall was not significantly thickened, and FDG uptake was normal.
Intestinal fullness was poor; the intestinal wall was not significantly thickened or lumpy, and FDG uptake was physiological.
The prostate was full, with punctate dense shadows; FDG uptake was not abnormally increased.
Bilateral inguinal canals were widened, containing fatty components.
The bladder was poorly full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
Overall muscle uptake was high; the spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Post-cervical spine surgery, with C5-7 vertebral body internal fixation using metal fixation, there were numerous surrounding artifacts.
Bilateral multiple rib bone tortuosity, FDG metabolism normal.
Left gluteal and thigh muscle atrophy.
Systemic bone marrow FDG metabolism normal.

Impression

1. Post-esophageal tumor surgery, no obvious space-occupying lesions were found in the esophageal wall, and FDG metabolism was normal. A follow-up gastroscopy is recommended.

2. Chronic inflammatory micronodules in both lungs. Emphysema in both lungs, a few post-inflammatory remnants in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Pleural thickening bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Benign prostatic hyperplasia with calcification. Widening of the bilateral inguinal canals, inguinal hernia to be ruled out; please correlate with clinical findings.

4. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge. Post-cervical spine surgery changes. Multiple old rib fractures bilaterally. Atrophy of the left gluteal and thigh muscles.

5. Senile brain, deep lacunar infarcts. Chronic inflammation of the bilateral maxillary sinuses with submucosal cysts.

6. The left lens is located in the posterior part of the eyeball; a 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.
