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 and small patchy low-density shadows in the deep bilateral cerebral regions, indicating decreased FDG uptake.
Some ventricles, sulci, fissures, and cisterns were slightly widened; the ventricles were symmetrical, and there was no midline shift.
Normal eyeball morphology and outline, clear retrobulbar structures, symmetrical optic nerves, and no abnormal FDG uptake.
No thickening of the paranasal sinus mucosa, and the sinus walls were intact.
No thickening of the nasopharyngeal wall, and no abnormal FDG uptake.
Symmetrical palatine tonsils, with physiological FDG uptake.
Normal laryngopharyngeal morphology and structure.
Normal morphology and density of the bilateral parotid and submandibular glands, with physiological FDG uptake.
The thyroid gland is normal in shape and size, with uneven density between the left and right lobes.
A small, slightly low-density nodule, approximately 0.8 cm in length, is also seen in the right lobe, with clear borders and normal FDG uptake.
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, or submental region.
Increased lung markings are observed bilaterally.
A soft tissue mass, approximately 8.3*4.3*5.1 cm in size, with an average CT value of 47 HU, is seen near the hilum of the right upper lobe.
The boundary between the mass and the adjacent mediastinum is indistinct in part.
The right upper lobe bronchus is truncated, and FDG uptake is increased (SUVmax = 8.6).
Patchy and linear areas of increased density are seen around and distal to the mass, with unevenly increased FDG uptake in some areas (SUVmax = 3.9).
A few linear shadows are seen in the remaining lungs, with normal FDG uptake.
Multiple nodular thickenings are seen in the right pleura, with increased FDG uptake (SUVmax = 4.3).
Right-sided pleural effusion with compression of part of the right lung.
Multiple lymph nodes are visible in the right hilum and mediastinum (prevascular, pretracheal, post-vena cava, and subcarinal).
The mediastinal lymph nodes show slightly increased density, with the largest having a short diameter of approximately 0.7 cm.
FDG uptake is increased, with an SUVmax of 5.8.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
No obvious masses or nodules are seen in either breast; FDG metabolism is not significantly abnormal.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
CT scan shows small nodular calcifications in the right lobe of the liver; FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall.
Punctate high-density lesions are observed within the gallbladder, but local FDG uptake is normal.
The pancreas is normal in shape, with no obvious 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 no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Both adrenal glands are slightly thickened, with a slightly increased FDG uptake (SUVmax = 2.8).
The stomach is poorly filled, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 5.1).
The intestines were poorly distended.
Nodular FDG uptake was observed in the upper abdomen, along the course of the small intestine (SUVmax = 9.8).
No significant thickening or masses were seen in the local intestinal wall.
The uterus was normal in shape and size, with no abnormal density shadows and normal FDG uptake.
No obvious abnormalities were seen in the bilateral adnexa.
The bladder was poorly distended, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation was seen in the abdomen or pelvis.
Increased FDG uptake was observed in the left parietal bone, multiple cervical, thoracic, lumbar, and sacral vertebrae and their appendages, bilateral scapulae, sternum, some bilateral ribs, bilateral iliac bones and acetabulum, bilateral ischial bones, right pubic tubercle, and upper left femur (SUVmax = 7.8).
Some of these areas showed uneven bone density increases, and some showed osteolytic bone destruction.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation; L3/4 intervertebral disc bulge, with no abnormalities observed in FDG uptake.

Impression

1. a. A soft tissue mass near the hilum of the right upper lobe with increased FDG metabolism, suggestive of malignancy, most likely lung cancer with obstructive changes. Please confirm the diagnosis with pathological examination. Multiple metastatic tumors in the right pleura, right pleural effusion. b. Multiple lymph node metastases in the right hilum and mediastinum. c. Multiple bone metastases throughout the body (see description for details). d. Bilateral adrenal hyperplasia is highly probable; please follow up to rule out metastasis.

2. A few post-inflammatory lesions in both lungs. Partial pulmonary edema in the right lung. Calcification of some arterial walls (including coronary arteries).

3. Calcification in the right lobe of the liver. Small gallstones.

4. Nodular FDG hypermetabolic lesions in the upper abdomen along the course of the small intestine, possibly physiological or inflammatory changes, space-occupying lesion to be ruled out, enhanced CT follow-up recommended. Chronic gastritis changes, gastroscopy follow-up recommended.

5. Spinal degenerative changes. L3/4 intervertebral disc bulge.

6. Bilateral deep cerebral ischemic lesions, mild age-related brain changes, MRI follow-up recommended to rule out micrometastases.

7. Uneven density between the left and right lobes of the thyroid gland; slightly low-density small nodules in the right lobe, FDG metabolism normal, possibly nodular goiter, 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.
