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: A few punctate low-density shadows were seen in the deep bilateral brain regions; FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
The ethmoid sinus mucosa was slightly thickened bilaterally, but the sinus walls were intact.
The nasopharyngeal wall was not thickened; FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in shape and structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was not abnormal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Multiple scattered patchy and flocculent ground-glass opacities were seen in the right lower lobe, with increased FDG uptake (SUVmax = 2.6).
A solid micronodule, approximately 0.2 cm in long diameter, with clear borders, was seen in the right middle lobe; FDG metabolism was normal.
Scattered linear opacities were seen in both lungs; punctate calcifications were seen in the left lower lobe.
No pleural thickening was observed bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar regions.
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was observed.
Irregular thickening of the lower thoracic esophageal wall was observed, with luminal narrowing, affecting a length of approximately 6.1 cm; FDG metabolism was increased (SUVmax = 22.3).
Multiple small lymph nodes were observed in the pretracheal space, aortic window, subcarinal region, and paraesophageal region of the posterior mediastinum.
The largest had a short diameter of approximately 0.5 cm.
FDG uptake was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no localized FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Several cystic lesions were observed in the left kidney, the largest with a long diameter of approximately 1.2 cm.
FDG uptake was absent in these lesions.
The right kidney is normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is normal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is full in shape, with a transverse diameter of approximately 5.1 cm, containing punctate calcifications.
Localized increased FDG uptake is seen in the right peripheral zone, with SUVmax = 7.3 and an uptake area of approximately 1.1*0.7 cm.
The bladder is generally distended, with several fine punctate dense shadows seen on the right wall.
A small amount of fluid is present in the tunica vaginalis of the left testis.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
No abnormalities were observed in FDG metabolism of any bones throughout the body.

Impression

1. A mass in the lower thoracic segment of the esophagus with increased FDG metabolism, consistent with esophageal cancer. Reactive hyperplasia of the mediastinal lymph nodes is highly probable; follow-up is recommended.

2. Multiple scattered chronic inflammations in the lower lobe of the right lung; anti-inflammatory treatment followed by a CT scan is recommended to rule out hidden lesions. Chronic inflammatory nodules (solid) in the middle lobe of the right lung. Bilateral pulmonary fibrosis, calcification in the lower lobe of the left lung. Calcification of some arterial walls (including coronary arteries).

3. Benign prostatic hyperplasia with calcification, localized high FDG metabolism in the right peripheral zone, suggestive of inflammatory changes; PSA and enhanced MRI are needed to rule out malignancy.

4. Left renal cyst. Bladder stones or wall calcifications. Small amount of hydrocele in the left testis.

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

6. A few ischemic foci in the deep bilateral cerebral regions; age-related brain.

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.
