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: Normal brain morphology and structure; patchy low-density shadows in the left basal ganglia, with unclear extent and decreased FDG metabolism; punctate slightly low-density shadows in the deep brain, with no abnormal FDG metabolism; widening of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Symmetrical bilateral eyeballs with no obvious abnormalities.
No thickening of the paranasal sinus mucosa; sinus walls intact.
Nasal septum deviation; no thickening of the nasopharyngeal wall; no abnormal FDG uptake; symmetrical bilateral pharyngeal recesses; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces with no abnormal FDG uptake.
No abnormal density shadows in the bilateral parotid and submandibular glands.
Normal morphology and structure of the oropharynx and laryngopharynx.
Thyroid gland is normal in shape and size, with decreased density in nodular patterns.
Calcification is seen in the left lobe.
FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear.
Several solid nodules with clear borders are present in both lungs.
The largest nodule is located in the right middle lobe, approximately 0.5 cm in diameter.
FDG uptake is normal.
Scattered linear lesions are present in both lungs.
FDG uptake is normal.
No pleural thickening is seen bilaterally.
There is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette is normal.
Calcification is present in some arterial walls (including coronary arteries).
No abnormal density shadows are seen in both breasts.
FDG metabolism is normal.
The esophagus is not dilated.
No significant thickening or mass is seen in the esophageal wall.
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 cystic lesion, approximately 1.1 cm in diameter, was observed in the left lobe of the liver, with normal FDG uptake.
The main portal vein showed no significant 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 normal 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.
Postoperatively, the right kidney was enlarged with a mixed-density mass with indistinct borders and a low-density necrotic area, measuring approximately 10.1*7.8*9.2cm.
FDG uptake was unevenly increased, with SUVmax=4.9, involving the renal pelvis and calyces.
Retroperitoneal lymph nodes were observed, the largest with a short diameter of approximately 0.7cm; FDG metabolism was normal.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
The left adrenal gland was thickened with slightly increased FDG uptake, SUVmax=2.4.
Calcification was seen in the right adrenal gland, with no abnormal FDG uptake.
The stomach was poorly distended, with slight thickening of the cardia, part of the gastric body, and antrum walls, and mildly increased FDG uptake, SUVmax=2.3.
The intestinal tract is not satisfactorily filled, with a considerable amount of residual contents within the intestinal lumen; intestinal uptake is physiological.
The uterus is normal in shape and size, with no abnormal density shadows, and FDG uptake is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly filled, with no obvious positive stones.
Osteophyte formation with fracture at the left anterior margin of the L2 vertebral body, with increased FDG uptake (SUVmax = 8.3, uptake diameter approximately 1.3 cm).
Systemic bone density is decreased; the spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, mild anterior displacement of the L4 vertebral body, and bulging of the L4/5 and L5/S1 intervertebral discs.
Muscle atrophy is present in both buttocks and thighs.
Patchy increased FDG uptake is observed in the left shoulder periarticular region (SUVmax = 3.5).

Impression

1. a. Post-right renal cell carcinoma surgery, right renal mass with increased FDG metabolism, suggestive of tumor recurrence; reactive hyperplasia of retroperitoneal lymph nodes. b. Osteophyte formation and fracture at the left anterior margin of the L2 vertebral body, increased FDG uptake, suggestive of post-fracture changes due to osteophyte formation; follow-up is recommended.

2. Elderly brain, softening lesion in the left basal ganglia, deep lacunar ischemic lesion in the brain; follow-up with MRI is recommended.

3. Nodular goiter; ultrasound follow-up is recommended.

4. Chronic inflammatory nodules in both lungs; CT follow-up is recommended. A few post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

5. Cyst in the left lobe of the liver. Hyperplasia of the left adrenal gland, calcification of the right adrenal gland.

6. Chronic inflammatory changes in some gastric walls; follow-up with endoscopy is recommended.

7. Osteoporosis, degenerative changes in the spine, mild anterior slippage of the L4 vertebral body, L4/5 and L5/S1 intervertebral disc bulge. Bilateral gluteal and thigh muscle atrophy. Left shoulder periarthritis.

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.
