Whole-body 18F-FDG PET/CT scan in a patient with Lung 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 punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
Slight thickening of the mucosa in the bilateral ethmoid sinuses; intact sinus walls; absent FDG metabolism.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Following chemotherapy for squamous cell carcinoma of the left upper lobe, two irregular mixed-density masses were observed in the apical-posterior segment and lingular segment of the left upper lobe, containing multiple air-filled septa, with spiculations around the lesions and pleural traction.
The former is slightly larger, with a cross-sectional size of approximately 4.5*4.1cm.
The solid component shows unevenly increased FDG metabolism, SUVmax=6.0, and faint patchy shadows are seen around the lesions.
Scattered solid nodules are present in both lungs, with regular shape, clear borders, and a long diameter of approximately 0.2-0.4cm.
FDG uptake is normal.
Calcification is present in the basal segment of the right lower lobe.
Increased translucency is observed in both lungs, with a few linear and flocculent density shadows also seen in both lungs.
FDG metabolism is normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Bilateral hilar lymph nodes were visualized; the largest had a short diameter of approximately 0.9 cm, with increased FDG metabolism and an SUVmax of 3.8.
The cardiac silhouette appeared normal.
The cardiac chamber density was lower than that of the myocardium.
Calcification was observed in some arterial walls (including the coronary arteries).
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan revealed several low-density nodules within the liver parenchyma, with smooth edges; the largest had a long diameter of approximately 0.5 cm, and no FDG metabolism was observed.
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 abnormalities in local FDG metabolism.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and no significant abnormalities in FDG metabolism were observed.
Spleen morphology, size, density, and FDG metabolism were normal.
Both kidneys were normal in shape and size.
A cystic low-density lesion with clear borders and a long diameter of approximately 2.0 cm was seen in the parenchyma of the left kidney, with absent FDG metabolism.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG metabolism was not significantly abnormal.
The left adrenal junction was slightly thickened, with slightly increased FDG metabolism (SUVmax = 2.7); the right adrenal gland showed no significant abnormalities on contrast.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG metabolism was not increased.
The stomach was poorly distended, with slightly thickened gastric walls and mildly increased FDG metabolism (SUVmax = 2.4).
The intestines were poorly distended, with slightly eccentric thickening of the middle and lower rectal wall and increased FDG metabolism (SUVmax = 6.1); the remaining colon and parts of the rectum showed increased FDG metabolism (SUVmax = 3.6).
The prostate is enlarged with a high-density shadow within the parenchyma; FDG metabolism is normal.
The bladder is poorly filled, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies.
A Schmorl's node is visible at the upper margin of the L5 vertebral body.
The L4/5 and L5/S1 intervertebral discs are bulging with pneumothorax and degeneration; FDG metabolism is normal.

Impression

1. a. Following chemotherapy for squamous cell carcinoma of the left upper lung, a mass is observed in the apical-posterior segment and lingular segment of the left upper lobe, with unevenly increased FDG metabolism in the solid component, suggesting continued tumor activity. There is slight inflammation around the lesion. b. Increased FDG metabolism is observed in the hilar lymph nodes of both lungs; no enlarged lymph nodes are seen in the mediastinum. Follow-up is recommended. c. Bilateral emphysema and scattered chronic inflammatory nodules (solid) in both lungs are present. Follow-up with CT scan is recommended. Calcification in the basal segment of the right lower lobe. A few post-inflammatory remnants in both lungs. Partial arteriosclerosis (including coronary arteries). Anemia is present.

2. Slightly eccentric thickening of the rectal wall in the middle and lower segments, with increased FDG metabolism, suggests inflammation is highly likely; neoplastic lesions should be ruled out. Colonoscopy is recommended for clarification. Increased FDG metabolism in the remaining colon and rectum suggests physiological uptake or chronic inflammatory changes. Chronic gastritis.

3. Left adrenal hyperplasia is highly probable; follow-up CT scan is recommended.

4. Liver cyst. Left kidney cyst. Benign prostatic hyperplasia with calcification.

5. Degenerative changes in the spine. Schmorl's node at the upper margin of the L5 vertebral body; L4/5 and L5/S1 intervertebral disc bulge with pneumoconiosis and degeneration.

6. Age-related brain changes; deep lacunar infarcts in the brain; MRI is recommended. 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.
