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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; and no significant abnormalities in FDG uptake were observed.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
Increased FDG uptake was observed on the right lateral wall of the nasopharynx (SUVmax = 6.6); the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear, and FDG uptake was normal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with uniform density, and FDG uptake was normal.
Multiple lymph nodes were observed bilaterally in the deep cervical spaces, submandibular region, and submental region, the largest with a transverse diameter of approximately 0.6 cm.
Some showed mild FDG uptake, with an SUVmax of 2.7.
A small nodule with a long diameter of approximately 0.2 cm was observed in the posterior basal segment of the left lower lobe.
A few linear shadows were observed in the right middle lobe, with no abnormal FDG uptake in either lung.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed bilaterally in the hilum and mediastinum.
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
Multiple lymph nodes were observed in the right axilla, the largest with a transverse diameter of approximately 0.4 cm.
One of them showed increased FDG metabolism, with an SUVmax of 2.9.
Both breasts were relatively dense, with no abnormal FDG metabolism.
The liver had irregular edges, a smaller liver volume, slightly widened hepatic fissures, unevenly decreased liver parenchymal density, and indistinct intrahepatic vessels; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was of acceptable morphology, with increased density in the lumen accompanied by punctate dense shadows; local FDG uptake was normal.
The pancreas was normal in morphology, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
Post-splenectomy, a high-density metallic shadow was observed in the surgical area, and several splenic nodules were also seen in the splenic flexure; physiological uptake was observed on FDG.
The stomach was poorly distended, and multiple punctate metallic density shadows were visible in the gastric wall; FDG uptake was normal.
A solid mass measuring approximately 3.2 2.1 cm was observed at the upper pole of the left kidney, with heterogeneous internal density, a visible capsule, and calcification in the wall; FDG uptake was increased, with SUVmax = 3.5.
Multiple cystic lesions were observed in both kidneys; multiple dense nodules were observed in the right kidney, the largest of which had a cross-section of approximately 1.1 0.9 cm; a small dense stone was also observed in the left kidney; FDG metabolism was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The uterus was normal in shape, with no abnormal density shadows, and FDG uptake was not abnormally increased.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes; FDG uptake was normal.
The sacral canal at the S1 vertebral level was enlarged, with cystic density shadows; FDG metabolism was normal.
The right 6th anterior rib showed no bone abnormalities; FDG metabolism was increased (SUVmax = 6.2).
A small subcutaneous soft tissue nodule was observed in the right upper arm, showing increased FDG uptake (SUVmax = 8.9).

Impression

1. a. Mass on the upper pole of the left kidney, with increased FDG metabolism, strongly suggesting renal cell carcinoma; please combine with enhanced MRI for comprehensive analysis. Multiple renal cysts and stones in both kidneys. b. Absence of the spleen with metallic density shadow on the stomach wall, suggesting postoperative changes and spleen regeneration. Gallstones and cholestasis. c. Trend towards cirrhosis, no abnormal FDG metabolism seen in the liver; please combine with enhanced MRI for comprehensive analysis. d. Increased FDG metabolism in the right 6th anterior rib, suggesting possible post-traumatic changes; metastasis to be ruled out; please consider clinical history and follow up.

2. Increased FDG metabolism on the right nasopharyngeal wall, suggesting possible inflammation; specialist examination recommended to rule out tumors. Reactive hyperplasia of bilateral deep cervical spaces, submandibular, and submental lymph nodes.

3. Chronic inflammatory micronodules in the lower lobe of the left lung. A few fibrotic lesions in the middle lobe of the right lung. Reactive hyperplasia of right axillary lymph nodes.

4. Spinal osteophyte formation, sacral canal cyst at the S1 vertebral level.

5. No obvious abnormalities seen on cranial imaging. There is a high probability of reactive hyperplasia of the subcutaneous lymph nodes in the right upper arm. Follow-up examination is recommended to rule out other possibilities.

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.
