Whole-body 18F-FDG PET/CT scan in a patient with Gallbladder 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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple hazy patchy shadows and nodular lesions are present in both lungs, more prominent in the right lower lobe; FDG uptake is normal.
Scattered linear lesions are present bilaterally; FDG uptake is normal.
Pleural thickening is present bilaterally; there is no pleural effusion or pneumothorax.
Lymph nodes are visible in the bilateral hilar, pretracheal, para-aortic arch, aortic window, and subcarinal lymph nodes; the largest has a short diameter of approximately 0.6 cm; FDG uptake is increased, SUVmax = 6.0.
Cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is present.
No abnormal density shadows were seen in the bilateral breasts; FDG metabolism is normal.
No esophageal dilation was observed, but FDG uptake was increased throughout the esophageal wall (SUVmax = 5.4).
Irregular thickening of the gallbladder fundus wall was observed with the formation of a soft tissue mass, with indistinct borders and uneven density, measuring approximately 4.0*3.8*4.3cm.
FDG uptake was increased (SUVmax = 20.0).
Multiple flocculent shadows were seen in the surrounding fat spaces.
Adjacent liver involvement was observed, with multiple low-density nodules and masses within the liver, some fused into patches, the largest measuring approximately 9.4*6.8cm, with increased FDG uptake (SUVmax = 25.0).
Multiple lymph nodes were visualized in the hepatic hilum, the largest with a short diameter of approximately 1.4cm, showing increased FDG uptake (SUVmax = 18.3).
Small retroperitoneal lymph nodes were also visualized, the largest with a short diameter of approximately 0.8cm, with no abnormalities in FDG metabolism.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
The bilateral adrenal glands are slightly enlarged with increased FDG uptake, SUVmax=5.7.
The stomach is poorly filled, with slight thickening of the antral wall and increased FDG uptake, SUVmax=5.2.
The intestines are poorly filled, with physiological uptake; the anal canal shows increased FDG uptake, SUVmax=9.2.
The uterus is normal in shape and size, with no abnormal density shadows and no abnormal FDG uptake.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder was poorly filled, but no obvious stones were observed.
Systemic bone density was decreased, but the spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 disc bulging.
The T3 and L5 vertebral bodies showed a palisade-like appearance.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Gallbladder lesion with elevated FDG metabolism, suggestive of malignancy, most likely gallbladder cancer; please confirm clinicopathologically. b. Multiple liver metastases. Hilar lymph node metastasis. Possible reactive hyperplasia of retroperitoneal lymph nodes; follow-up recommended.

2. Chronic inflammation and post-inflammatory remnants in both lungs. Bilateral pleural thickening. Reactive hyperplasia of hilar and mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Possible bilateral adrenal hyperplasia.

4. Chronic inflammatory changes in the entire esophagus and antrum of the stomach, hemorrhoidal changes; please confirm endoscopic follow-up.

5. Osteoporosis, degenerative changes in the spine, L4/5 intervertebral disc bulge. T3/L5 vertebral hemangioma.

6. Age-related brain lesions with deep lacunar infarcts; please include an MRI scan.

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.
