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 without significant 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 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: Normal in shape and size, with slightly uneven density; FDG uptake not abnormal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Several miliary nodules were seen in both lungs, approximately 0.2-0.3 cm in long diameter, with clear borders; FDG metabolism not abnormal.
A few patchy opacities and linear lesions were also seen in both lungs; FDG metabolism not abnormal.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette was normal.
Some arterial walls showed calcification.
The esophagus was not dilated; the esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
Liver: No significant abnormalities were seen in shape and size; liver margins were smooth; hepatic fissures were not widened; no significant abnormal density shadows were seen in the liver parenchyma on plain CT scan; FDG uptake was not abnormal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
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 abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
An irregular mass measuring approximately 5.5 4.3 cm was observed in the left renal pelvis and calyces, with increased FDG metabolism (SUVmax = 7.2), and dilation and hydronephrosis of the left renal pelvis and upper ureter.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, and ureter, and no obvious abnormal FDG uptake.
Both adrenal glands were slightly enlarged, with no abnormal FDG uptake.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is full in shape, with a transverse diameter of approximately 5.1 cm, and punctate calcifications are seen inside.
FDG metabolism is increased, with SUVmax=3.2.
Bladder distension is normal, and no obvious positive stones are seen inside.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
No abnormalities are seen in FDG metabolism in the whole bone marrow.

Impression

1. Mass in the left renal pelvis and calyces, with increased FDG metabolism, strongly suggestive of renal pelvis cancer; please correlate with clinicopathology. Dilatation and hydronephrosis of the left renal pelvis and upper ureter.

2. Chronic inflammatory miliary nodules in both lungs; follow-up CT scan recommended. A few chronic inflammatory lesions and old lesions in both lungs.

3. Calcification of some arterial walls.

4. Benign prostatic hyperplasia with calcification, increased FDG metabolism in the gland; follow-up PSA and ultrasound recommended. Bilateral adrenal hyperplasia.

5. Osteophyte formation in the cervical, thoracic, and lumbar vertebrae. L4/5 and L5/S1 intervertebral disc bulges.

6. No abnormalities found 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.
