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 ventricular system was enlarged, with widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The 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.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
A low-density nodule with relatively clear borders and a long diameter of approximately 0.6 cm was observed in the left lobe of the thyroid gland.
No abnormal FDG uptake was detected.
The right lobe of the thyroid gland was normal in shape and size, with uniform density, and no abnormal FDG uptake was detected.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
No abnormal FDG metabolism was detected.
Bronchiectasis was observed in the posterior segment of the left upper lobe and the apical segment of the right upper lobe, with patchy consolidation and calcification around the bronchi.
FDG uptake was increased, with SUVmax = 3.1.
Multiple solid nodules were observed in both lungs with relatively clear borders.
The largest nodule had a long diameter of approximately 0.3 cm, and some showed higher density and calcification.
No abnormal FDG uptake was detected.
Several small air-filled cysts were observed in the right lower lobe.
No abnormal FDG uptake was detected.
Scattered linear shadows were observed in both lungs.
No abnormal FDG uptake was detected.
The pleura was slightly thickened bilaterally, with punctate calcifications visible on the right side.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The pericardium was slightly thickened, and partial calcification was observed in the walls of the aorta and coronary arteries.
Following pacemaker implantation, the cardiac chamber density was lower than that of the myocardium.
Both breasts were relatively dense, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen showed no abnormalities in shape or size, with punctate calcifications observed internally, and FDG uptake was normal.
The right renal pelvis is enlarged, containing soft tissue density shadows with increased FDG uptake, measuring approximately 4.5 3.3 cm, with an SUVmax of 13.6.
The right renal parenchyma shows heterogeneous density with high-density shadows.
Multiple lymph nodes are seen in the right renal hilum and retroperitoneum, the largest with a short diameter of approximately 1.1 cm, showing increased FDG metabolism, with an SUVmax of 7.2.
The left kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is not increased.
The stomach is poorly filled, and the gastric wall is not significantly thickened; FDG uptake is not significantly abnormal.
A small air-filled sac is visible in the descending duodenum, with physiological FDG uptake.
The uterus is of normal shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
A cystic lesion with relatively clear borders, approximately 3.8 2.7 cm, is seen in the left adnexa; no abnormal FDG uptake is observed.
No abnormal FDG metabolism is seen in the right adnexa.
The bladder is generally full, with no obvious positive stones.
No obvious fluid accumulation is seen in the abdomen or pelvis.
Scoliosis, decreased bone density in all bones, osteophyte formation at the margins of some vertebral bodies, wedge-shaped change and slight posterior displacement of the L2 vertebral body, and bulging of the L3/4, L4/5, and L5/S1 intervertebral discs; no abnormal FDG uptake is observed.
Increased FDG metabolism in both shoulder joint capsules, SUVmax = 1.6.

Impression

1. Right renal pelvis mass with increased FDG uptake, suggestive of malignancy, most likely renal pelvis carcinoma; please correlate with clinicopathology. Multiple lymph node metastases in the right renal hilum and retroperitoneum. Residual contrast agent in the right renal parenchyma.

2. a. Bronchiectasis with infection in the apical-posterior segment of the left upper lobe and the apical segment of the right upper lobe; multiple chronic inflammatory micronodules with calcifications in both lungs; small air-filled cysts in the right lower lobe; a few post-inflammatory lesions in both lungs. b. Slight pleural thickening with right-sided calcification. Slight pericardial thickening; partial calcification of the aorta and coronary artery walls, post-pacemaker implantation changes; mild anemia.

3. Duodenal diverticulum in the descending part.

4. Splenic calcifications. Left ovarian cyst; ultrasound follow-up recommended.

5. Low-density nodule in the left lobe of the thyroid gland; no abnormal uptake was observed on FDG, suggestive of nodular goiter; ultrasound and thyroid function tests are recommended.

6. Osteoporosis. Scoliosis with bone hyperplasia. L2 vertebral body wedge-shaped deformity with slight posterior slippage. L3/4, L4/5, and L5/S1 intervertebral disc bulges. Bilateral frozen shoulder.

7. Senile cerebral atrophy.

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.
