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 in FDG uptake were observed.
No widening was observed in the ventricles, sulci, fissures, or cisterns; no abnormalities were observed in local density or FDG uptake; and no midline shift was observed.
The bilateral eyeballs showed normal morphology and contours; the retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and no significant abnormalities in FDG uptake were observed.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; increased FDG uptake was observed on both sides (SUVmax = 6.4); the bilateral pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube opening; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and no abnormalities in FDG uptake were observed.
The bilateral palatine tonsils and the base of the tongue were full; and increased FDG uptake was observed (SUVmax = 11.9).
No abnormalities were observed in the morphology and structure of the laryngopharynx.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Multiple lymph nodes are seen in the bilateral deep cervical spaces and submandibular region, the largest being approximately 1.2 cm in short diameter; some show increased FDG uptake (SUVmax = 4.5).
The chest is symmetrical, with clear lung markings.
Several solid nodules, approximately 0.4 cm in long diameter, are seen in the left lower lobe; FDG uptake is normal.
The trachea is midline, and the trachea and segmental bronchi are patent.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions; FDG uptake is normal.
The pleura is not thickened bilaterally, and there is no pleural effusion or pneumothorax.
The cardiac silhouette is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is normal.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
The liver parenchyma has decreased density, with a CT value of approximately 49 HU; FDG uptake is 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, no positive stones or obvious masses, and normal 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 normal FDG uptake.
The spleen was normal in shape and size, density, and FDG uptake.
A soft tissue density lesion protruding beyond the renal contour was observed at the lower pole of the left kidney, with indistinct borders, measuring approximately 3.1*3.0cm, with a CT value of approximately 26 HU, uneven FDG uptake, and SUVmax=2.9.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and normal FDG uptake.
The renal pelvis, calyces, and ureters were normal bilaterally, and no positive stones were observed.
The adrenal glands were normal in shape and density bilaterally, and normal FDG uptake was normal.
Small lymph nodes, approximately 0.4 cm in short diameter, were observed in the retroperitoneum, mesentery, and bilateral inguinal regions; FDG uptake was normal.
No significant fluid accumulation was observed in the abdomen or pelvis.
Gastric distension was poor, with increased FDG uptake in some gastric walls (SUVmax = 4.0).
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, but increased FDG uptake was observed in some intestinal segments (SUVmax = 6.8).
The prostate gland was normal in shape and size, approximately 3.9 cm in transverse diameter, with calcifications in the parenchyma; FDG uptake was not significantly increased.
Bladder distension was poor, with no obvious positive stones observed.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, L4/5 disc bulging, and L5/S1 disc herniation with posterior calcification.

Impression

1. a. Mass at the lower pole of the left kidney, with uneven FDG metabolism, highly suggestive of a neoplastic lesion; please confirm with contrast-enhanced MRI. b. Reactive hyperplasia of the retroperitoneal, mesenteric, and bilateral inguinal lymph nodes is highly likely; please follow up.

2. Chronic inflammatory nodule in the lower lobe of the left lung; please confirm with CT.

3. Fatty liver, no abnormal FDG metabolic foci seen in the liver parenchyma. Prostatic calcification.

4. Increased FDG metabolism in parts of the gastric wall and intestinal tract, possibly due to physiological uptake or chronic inflammation; please confirm with endoscopy.

5. Partial vertebral osteophyte formation. L4/5 disc bulge, L5/S1 disc herniation with posterior margin calcification.

6. Uneven thyroid density; please confirm with ultrasound.

7. No obvious abnormalities seen on cranial scintigraphy. Chronic inflammation of the nasopharynx, bilateral palatine tonsils, and base of the tongue. Reactive hyperplasia of the bilateral deep cervical spaces and submandibular lymph nodes.

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.
