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:Normal brain morphology and structure, no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG metabolism.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Normal morphology and contour of the bilateral eyeballs, clear retrobulbar structures, symmetrical optic nerves, and no abnormal FDG metabolism.
Slight thickening of the mucosa in the bilateral ethmoid sinuses, with intact sinus walls and absent FDG metabolism.
Slight thickening of the nasopharyngeal wall and symmetrical fullness of the bilateral palatine tonsils in the oropharynx, with increased FDG metabolism (SUVmax = 8.2).
No stenosis of the bilateral pharyngeal recesses or Eustachian tube openings, normal structures of the infratemporal fossa and pterygopalatine fossa, and clear bilateral parapharyngeal spaces, with no abnormal FDG metabolism.
FDG metabolism in the oropharynx and laryngopharynx was physiological.
No abnormalities were observed in the bilateral parotid and submandibular glands.
The right lobe of the thyroid gland showed uneven density, with no abnormalities in FDG metabolism.
Small lymph nodes were visible in the bilateral deep cervical spaces, the largest with a short diameter of approximately 0.6 cm, showing slightly increased FDG metabolism (SUVmax = 2.4).
Small patchy, blurred shadows were seen in the right lower lobe, with increased FDG metabolism (SUVmax = 5.8), containing regular bronchial air-filled shadows.
A pure ground-glass opacity nodule with a long diameter of approximately 0.4 cm was seen in the posterior segment of the right lower lobe, with indistinct borders and a maximum CT value of approximately -513 HU; FDG metabolism was normal.
Scattered solid nodules were observed in both lungs, with regular shapes and clear borders, with a long diameter of approximately 0.3-0.5 cm; FDG uptake was normal.
A few linear and flocculent density shadows were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Lymph nodes were visualized in the right hilar and mediastinal areas (pretracheal, posterior to the vena cava, aortic window, and subcarinal), the largest measuring approximately 0.7 cm in short diameter, with increased FDG metabolism and an SUVmax of 4.5.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
Bilateral breasts showed slightly dense fibroadenomas in some areas, and dense nodular changes in others, the largest measuring approximately 0.4 cm in long diameter, with no significant abnormalities in FDG metabolism.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
A small, low-density nodule with smooth margins, approximately 0.4 cm in long diameter, was observed in the parenchyma of the right lobe of the liver on plain CT scan, with absent FDG metabolism.
Punctate high-density shadows appeared within the bile ducts of the right lobe of the liver.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder appears normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG metabolism.
The pancreas appears normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG metabolism.
The spleen appears normal in shape, size, density, and FDG metabolism.
Both kidneys appear normal in shape and size, with punctate high-density shadows in the parenchyma of the left kidney.
The renal pelvis, calyces, and ureters appear normal, and FDG metabolism is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The upper esophagus near the thoracic inlet shows irregular thickening of the esophageal wall, resembling a mass, with a cross-sectional size of approximately 2.4*2.1*3.3cm.
FDG metabolism is increased, SUVmax=22.5, locally compressing the left lobe of the thyroid gland.
Lymph nodes are visible around the lesion and in the left supraclavicular fossa, the largest being approximately 0.6cm in short diameter, some with increased FDG metabolism, SUVmax=3.1.
The cardia wall is slightly thickened, with increased FDG metabolism, SUVmax=3.6.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall; FDG metabolism is physiological.
The greater curvature of the stomach wall is slightly thickened, with increased FDG metabolism, SUVmax=4.6.
The uterus has an irregular shape.
A mass of isodense density is seen on the left wall of the uterine fundus, with indistinct borders, a cross-sectional size of approximately 4.3*5.3cm, and relatively homogeneous density within it; FDG metabolism is background-like.
The cervix shows patchy low-density shadows with absent FDG metabolism.
No obvious abnormalities were observed in the bilateral adnexal regions.
The bladder was poorly filled, but no obvious positive stones were seen.
The lesser omental bursa and small lymph nodes para-aortic lymph nodes were visible, with a short diameter of approximately 0.3-0.4 cm; FDG metabolism was normal.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges were observed; FDG metabolism was normal.
Punctate dense bone shadows were observed in the right femoral head; FDG metabolism was normal.

Impression

  1. a. A mass in the cervical segment of the esophagus, with increased FDG metabolism, consistent with esophageal cancer. Possible metastasis to the surrounding lymph nodes and left supraclavicular fossa; please correlate with clinicopathology. The left lobe of the thyroid gland is compressed. b. Slight thickening of the cardia wall, with increased FDG metabolism, consistent with cardia cancer based on the gastroscopy report. c. Slight thickening of the gastric wall on the greater curvature of the gastric body, with increased FDG metabolism, suggesting possible inflammation; follow-up gastroscopy is recommended. d. Reactive hyperplasia of the lesser omental sac and para-aortic lymph nodes; follow-up is recommended.

  2. a. Partial active inflammation in the lower lobe of the right lung; follow-up with CT scan after anti-inflammatory treatment is recommended. Reactive hyperplasia of the right hilar and mediastinal lymph nodes; please follow up to rule out partial metastasis. b. Pure ground-glass opacity nodule in the posterior segment of the right lower lobe, suggestive of chronic inflammatory nodule or atypical adenomatous hyperplasia; CT follow-up is recommended. c. Scattered small chronic inflammatory nodules (solid) in both lungs; CT follow-up is recommended. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis (including coronary arteries). Bilateral breast hyperplasia, some showing nodular changes.

  3. Slight thickening of the nasopharyngeal wall and possible inflammation of bilateral palatine tonsils in the oropharynx; specialist follow-up is recommended. Reactive hyperplasia of bilateral deep cervical lymph nodes.

  4. Small cyst in the right lobe of the liver; calcification in the bile duct of the right lobe of the liver. Calcification in the left kidney. Uterine fibroids are highly probable; Nabothian cysts of the cervix; ultrasound follow-up is recommended.

  5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges. Small bony island in the right femoral head.

  6. No obvious abnormalities were found on cranial scintigraphy. Minor inflammation of both ethmoid sinuses.

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.
