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: Normal brain morphology and structure, with a few patchy low-density shadows in the deep brain regions; FDG uptake was not significantly abnormal.
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 and showed no significant abnormalities.
A submucosal cyst was present in the left maxillary sinus, with an intact sinus wall.
No thickening of the nasopharyngeal wall was observed; FDG uptake was not abnormal; both 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 not abnormal.
Both palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; calcifications with a long diameter of approximately 0.2-0.3 cm were observed in the right lobe and isthmus; FDG uptake was not abnormal.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, with normal FDG metabolism.
A mixed ground-glass nodule with clear borders and a long diameter of approximately 0.6 cm was seen in the posterior basal segment of the left lower lobe, and another ground-glass nodule with clear borders and a long diameter of approximately 0.5 cm was seen in the posterior segment of the left lower lobe, with normal FDG uptake.
Several solid small nodules with clear borders and a long diameter of approximately 0.2-0.7 cm were observed in both lungs, with no increased FDG metabolism.
Partial bronchiectasis with thickened bronchial walls and multiple patchy high-density shadows around the bronchi.
Scattered cystic lucent shadows were observed in both lungs.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
One lymph node was observed each next to the trachea in the superior mediastinum and next to the descending aorta in the posterior mediastinum, the larger one with a short diameter of approximately 0.8 cm, and increased FDG metabolism (SUVmax = 6.6).
Calcification of some arterial walls (including coronary arteries) was observed.
The cardiac silhouette was normal.
Thickening of the mid-thoracic esophagus with soft tissue shadows, measuring approximately 4.5*3.4*4.8cm, with increased FDG metabolism (SUVmax = 19.0).
Liver morphology and size are normal, with smooth liver margins and no widening of the hepatic fissure.
CT scan shows a low-density shadow approximately 0.3cm in length in the right posterior lobe of the liver, with no abnormal FDG uptake.
Calcification is present in the right lobe of the liver.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with slightly increased density within the gallbladder; 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.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with small punctate dense shadows in both kidneys; the renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal glands show no significant abnormalities on contrast.
The stomach is poorly filled, with slight thickening of the gastric wall in the antrum.
FDG metabolism is mildly increased, with SUVmax=3.7.
The intestines are poorly filled, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
A low-density mass is seen on the mesentery in the right lower quadrant, with a CT value of approximately 19 HU and a size of approximately 2.8*2.0 cm; FDG metabolism is not increased.
The prostate is enlarged, with a transverse diameter of approximately 5.9 cm, uniform density, and unevenly increased FDG uptake, with SUVmax=2.7.
The bladder is generally full, with no obvious positive stones.
Calcification is present in the tunica vaginalis of the left testis.
Increased fat density is seen around the root of the mesentery, containing multiple small nodules, with a long diameter of approximately 7 mm; FDG uptake is not abnormal.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with calcification of the nuchal ligament.
Osteophyte formation is present at the margins of some vertebral bodies; L4/5 and L5/S1 intervertebral disc bulges are present.
Narrowing of the L2/3 and L4/5 intervertebral spaces.
Multiple pneumothoraxes in the lumbar intervertebral discs.
No abnormal FDG metabolism was observed in the entire skeletal system.
A fat density shadow measuring approximately 4.6*1.8cm was observed on the medial side of the right scapula; FDG metabolism was not increased.

Impression

  1. Thickening of the mid-thoracic esophagus with soft tissue mass, increased FDG metabolism, consistent with esophageal cancer. Metastasis to the right paratracheal and para-aortic lymph nodes in the superior mediastinum and posterior mediastinum.

  2. Mixed ground-glass nodules in the posterior basal segment of the left lower lobe and ground-glass nodules in the posterior segment of the left lower lobe, with no increased FDG metabolism, both suggestive of chronic inflammatory nodules. Several solid chronic inflammatory nodules in both lungs, please follow up with CT scan. Changes in chronic bronchitis and emphysema in both lungs.

  3. Calcification of some arterial walls (including coronary arteries).

  4. Cyst in the right posterior lobe of the liver. Calcification in the right lobe of the liver. Cholestasis in the gallbladder.

  5. Slight thickening of the gastric wall in the antrum, with mildly increased FDG metabolism, suggestive of inflammatory uptake, please follow up with gastroscopy.

  6. a. Localized low-density lesion in the right lower abdomen above the mesentery, with normal FDG metabolism, suggestive of benign lesion, please follow up. b. Increased fat density and multiple small nodules around the root of the mesentery, with no abnormal FDG uptake, suggest panniculitis is highly likely; please correlate with clinical findings and conduct follow-up examinations.

  7. Small kidney stones in both kidneys. Benign prostatic hyperplasia, with unevenly increased FDG uptake, suggests chronic inflammation is highly likely; PSA testing is recommended.

  8. Spinal degenerative changes. L4/5 and L5/S1 intervertebral disc bulges. L2/3 and L4/5 intervertebral space narrowing. Multiple pneumothorax in the lumbar intervertebral discs. Lipoma on the medial side of the right scapula.

  9. A few ischemic foci deep in the brain. Submucosal cyst of the left maxillary sinus. Calcifications in the right lobe and isthmus of the thyroid gland; please follow up with ultrasound.

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.
