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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no significant abnormalities were observed.
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 not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple solid nodules with well-defined borders are present in both lungs, the largest being approximately 1.3 cm in diameter in the medial segment of the right middle lobe, with increased FDG uptake (SUVmax = 5.1).
Scattered linear lesions are present bilaterally, with no abnormal FDG uptake.
No pleural thickening is seen bilaterally; no pleural effusion or pneumothorax is present bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal; cardiac chamber density is lower than myocardial density.
Some arterial walls show calcification (including coronary arteries).
Both breasts are slightly dense; punctate dense shadows are seen in the right breast; FDG metabolism is normal.
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 abnormal local FDG uptake.
Normal pancreas shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
A soft tissue density nodule adjacent to the spleen, approximately 1.2 cm in diameter, with no abnormal FDG uptake.
An irregular, mixed-density mass in the upper middle part of the left kidney, with indistinct borders and uneven density, containing low-density necrotic areas, measures approximately 10.0*8.8*9.2cm.
FDG uptake is unevenly increased, SUVmax=13.1.
The mass invades the renal pelvis, calyces, and retrorenal fascia, and its boundary with the adjacent spleen is indistinct.
Small retroperitoneal lymph nodes are visible, the largest with a short diameter of approximately 0.6cm; FDG metabolism is normal.
The right kidney is normal in shape and size, with a small cystic lesion in the right renal parenchyma, approximately 0.8cm in diameter.
FDG metabolism is normal.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
Poor gastric filling, slight thickening of the cardia and antral walls, increased FDG uptake, SUVmax=3.5.
Intestinal distension was unsatisfactory, but intestinal uptake was physiological.
The uterus is absent following a hysterectomy.
No obvious abnormalities were observed in the bilateral adnexa.
Bladder distension was poor, but no obvious positive stones were seen.
Systemic bone density was decreased, spinal alignment was normal, with some vertebral marginal osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
Patchy FDG uptake was observed bilaterally around the shoulders, with SUVmax = 4.5.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Left renal mass with increased FDG metabolism, consistent with renal cell carcinoma, involving the spleen. Reactive hyperplasia of small retroperitoneal lymph nodes. b. Multiple metastatic tumors in both lungs.

2. Scattered post-inflammatory lesions in both lungs. Anemia changes, partial calcification of arterial walls (including coronary arteries).

3. Bilateral breast hyperplasia, calcification in the right breast.

4. Accessory spleen. Small cyst in the right kidney. Post-uterine surgery changes.

5. Partial chronic inflammatory changes in the gastric wall.

6. Osteoporosis, degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulge. Bilateral frozen shoulder.

7. No obvious abnormalities seen on cranial scintigraphy.

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.
