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: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no obvious abnormalities were seen.
FDG metabolism was increased in some periodontal tissues, with SUVmax = 5.6.
The bilateral maxillary sinus mucosa was thickened, but the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was not abnormal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with uniform density; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Multiple diffuse solid nodules of varying sizes are seen in both lungs, the largest being approximately 2.6 cm in long diameter; FDG metabolism is increased, SUVmax = 4.9.
A few punctate and linear lesions are seen in both lungs; FDG metabolism is normal.
The pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Multiple small lymph nodes are seen in the mediastinum; FDG uptake is normal.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated; the wall is not significantly thickened or swollen; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A low-density lesion, approximately 1.3 cm in long diameter, was observed at the top of the diaphragm, with increased FDG metabolism (SUVmax = 9.3).
No other obvious abnormal density shadows or FDG uptake were observed in the remaining liver parenchyma.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A soft tissue mass with clear borders, involving the renal pelvis, is seen at the upper pole of the left kidney.
It exhibits heterogeneous density, with an average CT value of approximately 34 HU and a size of approximately 5.6 5.3 6.5 cm.
FDG metabolism is increased, with an SUVmax of 12.6.
Extensive thickening of the perirenal fascia is observed.
Several enlarged lymph nodes are seen at the left renal hilum and adjacent to the abdominal aorta, the largest with a short diameter of approximately 1.4 cm.
FDG metabolism is increased, with an SUVmax of 14.2.
The left adrenal gland shows nodular thickening, with a long diameter of approximately 1.0 cm.
FDG metabolism is increased, with an SUVmax of 6.9.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is normal.
No obvious abnormalities are seen on the right adrenal gland.
The stomach is poorly distended, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was full in shape, approximately 5.1 cm in diameter, with punctate calcifications inside; FDG metabolism was slightly increased, SUVmax = 3.2.
The bladder was generally full, with no obvious positive stones.
No obvious fluid accumulation was observed in the abdomen or pelvis.
Calcification of the nuchal ligament was present.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Mass on the upper pole of the left kidney, with increased FDG metabolism, suggestive of renal cell carcinoma. b. Multiple lymph node metastases in the left renal hilum and para-aortic region. Extensive metastases in both lungs. Metastasis to the diaphragmatic roof of the liver. High probability of left adrenal metastasis.

2. Minor chronic inflammation and old lesions in both lungs. Slight pleural thickening bilaterally. Reactive hyperplasia of mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Benign prostatic hyperplasia with calcification, mildly increased FDG metabolism, suggestive of inflammatory or physiological uptake; follow-up PSA and ultrasound examination recommended.

4. Nuchal ligament calcification. Osteophyte formation in the cervical, thoracic, and lumbar vertebrae; L4/5 and L5/S1 intervertebral disc bulges.

5. Minor ischemic lesions in the deep bilateral brain; senile encephalopathy. Chronic inflammation of the bilateral maxillary sinuses. Inflammation of some periodontal tissues.

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.
