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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; no abnormalities were observed in FDG uptake.
Bone destruction and soft tissue mass formation in the right mandibular ramus, approximately 4.1*3.4cm in size, with increased FDG metabolism (SUVmax=12.0).
Multiple enlarged lymph nodes were observed in the right submandibular region, bilateral supraclavicular fossa, mediastinum, hepatogastric space, hilar space, and retroperitoneum, the largest with a short diameter of approximately 1.3cm, showing increased FDG metabolism (SUVmax=8.3).
Multiple solid nodules were observed in both lungs, the largest with a long diameter of approximately 2.8cm, showing increased FDG metabolism (SUVmax=8.4).
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Calcification of some arterial walls was observed.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, and no significant thickening or mass was observed in the esophageal wall; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal 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 significant abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A large cystic-solid mass was observed in the right kidney, approximately 14.0*11.0 cm in cross-section, with increased FDG uptake in the solid portion (SUVmax=4.7), and liver compression changes.
The left kidney was normal in shape, with no widening of the renal pelvis, calyces, or ureter, and no significant abnormal FDG uptake.
The left adrenal gland was thickened, with increased FDG metabolism (SUVmax=4.7).
The right adrenal gland was not clearly visualized.
The stomach was poorly distended, with no significant thickening of the stomach wall and no significant abnormal FDG uptake.
The intestines were poorly distended, with no significant thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate is enlarged, approximately 5.2 cm in diameter, with calcifications visible.
FDG uptake is not abnormally elevated.
The bladder is generally full, with no obvious positive stones.
No significant fluid accumulation is observed in the abdomen or pelvis.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 disc bulging.
Multiple areas show elevated FDG metabolism (SUVmax = 8.3) in the left humerus, left scapula, multiple vertebral bodies and appendages, left 4th rib, and right femoral head.

Impression

1. a. Bone destruction and soft tissue mass formation in the right mandibular ramus with increased FDG uptake, suggestive of a metastatic tumor. Multiple bone metastases throughout the body. b. Multiple lymph node metastases in the right submandibular region, bilateral supraclavicular fossa, mediastinum, hepatogastric space, hilar space, and retroperitoneum. Multiple lung metastases. c. Enlarged left adrenal gland with increased FDG metabolism, suggestive of a metastatic tumor.

2. A large mass in the right kidney, suggestive of a malignant tumor, most likely renal cell carcinoma. The right adrenal gland is not clearly visualized.

3. Benign prostatic hyperplasia with calcification.

4. Osteophyte formation in some vertebrae. L4/5 and L5/S1 intervertebral disc bulges.

5. No obvious abnormalities were 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.
