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, with a few patchy low-density shadows in the deep brain regions; 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, with no obvious abnormalities.
There was slight mucosal thickening in the bilateral maxillary sinuses, but the sinus walls were intact.
The nasopharyngeal walls were not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Physiological uptake was observed in the bilateral palatine tonsils.
Several small nodules were seen in the bilateral parotid glands, the largest being approximately 0.7 cm in long diameter, with increased FDG metabolism (SUVmax = 12.7).
No abnormal density shadows were seen in the bilateral submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly uneven density; a low-density nodule and punctate calcifications were seen in the right lobe, approximately 0.8 cm in diameter.
FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Scattered solid micronodules were seen in both lungs, with clear borders, approximately 0.2?.3 cm in diameter; FDG uptake was normal in all lungs.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Mediastinal lymph nodes were visible; the largest had a short diameter of approximately 0.5 cm, with increased FDG metabolism (SUVmax = 5.6).
Calcification of some arterial walls (including coronary arteries) was observed.
The cardiomegaly was present.
The esophagus was not dilated; no significant thickening or mass was seen in the esophageal wall, and FDG uptake was normal.
No obvious abnormal density was observed in either breast, and FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A low-density shadow with a long diameter of approximately 0.5 cm was observed in the left lobe of the liver, with clear borders; 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 normal in shape and size, with thickened gallbladder walls; FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
A slightly low-density soft tissue mass, approximately 2.6 x 3.9 cm in size, is seen in the upper part of the right kidney.
The mass has indistinct borders, and FDG metabolism is increased (SUVmax = 4.2), involving the renal pelvis.
A punctate dense shadow is seen in the left renal calyx.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with slight thickening of the gastric wall in the antrum.
FDG metabolism is mildly increased (SUVmax = 4.2).
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The uterus is normal in shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism is seen in the bilateral adnexa.
The bladder wall shows no abnormal thickening, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdominopelvic region or retroperitoneal area.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
Bone destruction with soft tissue shadow in the right 8th posterior rib and right T8 adnexa, approximately 3.8*2.8cm in size, with increased FDG metabolism and SUVmax=4.1; bone destruction with a large soft tissue mass in the right iliac bone, approximately 10.8*8.6cm in size, with increased FDG metabolism and SUVmax=5.3.
Bilateral pars interarticularis fracture at L5, anterior displacement of the L4 and L5 vertebral bodies, partial vertebral body marginal osteophyte formation, and L1-S1 intervertebral disc bulge.
No obvious abnormalities were found in the lower extremities.

Impression

1. a. Bone metastases in the right 8th posterior rib, right adnexa of T8, and right iliac bone. b. Right renal mass with increased FDG metabolism, highly suggestive of renal cancer; enhanced MRI is recommended for further examination.

2. Minor chronic inflammation of bilateral maxillary sinuses. Reactive hyperplasia or adenolymphoma of bilateral parotid lymph nodes; ultrasound follow-up is recommended.

3. Scattered chronic inflammatory micronodules (solid) in both lungs; follow-up CT is recommended. Reactive hyperplasia of mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries). Cardiac enlargement.

4. Small hepatic cysts. Chronic cholecystitis. Left renal calculi.

5. Physiological changes or inflammatory lesions in the gastric antrum; gastroscopy follow-up is recommended.

6. Bilateral pars interarticularis fracture of L5, anterior slippage of L4 and L5 vertebral bodies. Spinal osteophyte formation. L1-S1 intervertebral disc bulge.

7. A few ischemic lesions deep in the brain, age-related brain changes.

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

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.
