Whole-body 18F-FDG PET/CT scan in a patient with Renal 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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
Multiple enlarged lymph nodes were observed in the left deep cervical space and left supraclavicular fossa, the largest measuring approximately 1.3 cm in short diameter, with increased FDG uptake (SUVmax = 7.0).
The thyroid gland was normal in shape and size, but its density was somewhat uneven; FDG uptake was not abnormal.
The lung markings were clear bilaterally, with calcification in the posterior segment of the left upper lobe and scattered linear lesions in both lungs; FDG uptake was not abnormal.
Bilateral pleural thickening was present, but there was no pleural effusion or pneumothorax.
Multiple lymph nodes were visible in the hilar region, mediastinum, and left axilla, the largest measuring approximately 0.8 cm in short diameter, with increased FDG uptake (SUVmax = 5.9).
The cardiac silhouette was normal, but the cardiac chamber density was lower than that of the myocardium; some arterial walls (including the coronary arteries) showed calcification.
Both breasts showed dense glandular tissue, with punctate dense shadows seen in the right breast; FDG metabolism was not abnormal.
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities in liver shape and size, smooth liver margins, no widening of the liver fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan; no abnormal FDG uptake.
No obvious widening of the main portal vein, and no dilation of intrahepatic or extrahepatic bile ducts.
No abnormalities in gallbladder shape and size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Normal pancreas shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
No abnormalities in spleen shape, size, density, or FDG uptake.
Increased FDG metabolism in the upper pole of the left kidney, with an uptake area of approximately 2.9*2.1cm, SUVmax=6.3, and slightly increased density on the same CT slice.
A slightly low-density lesion, approximately 0.8 cm in diameter, was observed in the middle of the right kidney.
FDG metabolism was normal.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was poorly filled, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake was increased, with SUVmax = 2.6, more pronounced in the antrum.
Intestinal filling was unsatisfactory, with linear calcification of part of the colorectal wall and increased FDG uptake in some parts of the intestine, with SUVmax = 4.3.
The uterus was normal in shape and size, with no abnormal density shadows and no abnormal FDG uptake.
No significant abnormalities were observed in the bilateral adnexa.
The bladder was poorly filled, with no obvious positive stones.
A small amount of pelvic effusion was present.
Multiple enlarged lymph nodes were observed bilaterally in the retroperitoneal space, around the major blood vessels in the diaphragmatic crura, in the mesentery of the abdominoperineal cavity, beside the bilateral iliac vessels, in the bilateral pelvic walls, and in the bilateral inguinal regions.
Some of these lymph nodes were fused together in clusters.
The largest node, located retroperitoneally, measured approximately 5.8 x 3.8 cm.
FDG uptake was increased, with an SUVmax of 10.3.
The spinal alignment was normal, with some vertebral body margin osteophytes and multiple lumbar intervertebral disc bulges.
No abnormalities were observed on imaging of the bilateral lower extremities.
Subcutaneous edema was present in the abdomen and buttocks.
Focal FDG uptake was observed in the right segment of the L5 vertebral body, with an SUVmax of 3.9.

Impression

1. a. Multiple enlarged lymph nodes throughout the body with increased FDG metabolism (see description for details), consistent with metastatic lesions based on pathology. b. Focal increased FDG metabolism in the right part of the L5 vertebral body, highly suggestive of metastatic lesions; close observation is recommended.

2. Increased FDG metabolism in the upper pole of the left kidney; slightly increased density on the same CT scan, suggestive of a space-occupying lesion; further enhanced MRI of both kidneys is recommended. Slightly low-density lesion in the middle of the right kidney; no abnormal FDG metabolism; highly suggestive of a cyst.

3. Calcification in the upper lobe of the left lung. A few post-inflammatory lesions in both lungs. Bilateral pleural thickening. Anemia changes; partial calcification of arterial walls (including coronary arteries).

4. Bilateral breast hyperplasia; calcification in the right breast.

5. Schistosomiasis intestinal changes; possible chronic inflammatory changes in part of the gastric wall and intestinal tract; endoscopic examination is recommended. Small amount of pelvic effusion.

6. Degenerative changes in the spine, multiple bulging lumbar intervertebral discs. Subcutaneous edema in the abdomen and buttocks.

7. Age-related brain conditions, deep lacunar infarcts.

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.
