Whole-body 18F-FDG PET/CT scan in a patient with Prostate 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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: Normal brain morphology and structure, white matter degeneration, and punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical; a high-density nodule, approximately 0.6 cm in long diameter, was observed below the left eyeball; FDG metabolism was normal.
Slight thickening of the left maxillary sinus mucosa was observed, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
Slight thickening of the nasal septum was observed, but the nasopharyngeal wall was not thickened; both palatine tonsils were symmetrical, and FDG uptake was physiological.
Laryngopharynx morphology and structure were normal.
Bilateral parotid and submandibular glands showed normal morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Lung markings were clear bilaterally.
Several small solid nodules were observed in the upper lobes of both lungs and the posterior basal segment of the right lower lobe, the largest being approximately 0.3 cm in diameter; no abnormal FDG uptake was observed.
A roundish, air-filled cavity was observed in the apical-posterior segment of the left upper lobe.
Scattered linear lesions were observed in both lungs; no abnormal FDG uptake was observed.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Lymph nodes were visualized in the hilar region, pretracheal region, posterior to the vena cava, para-aortic arch, and para-ascending aorta; the largest had a short diameter of approximately 1.0 cm, and increased FDG uptake (SUVmax = 7.1).
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
No esophageal dilatation was observed; increased FDG uptake was observed in the lower esophageal wall (SUVmax = 3.4).
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
Multiple nodular dense shadows were seen in the gallbladder, but the gallbladder wall was not thickened, and local FDG uptake was normal.
The pancreas was normal in shape, with punctate dense shadows in the pancreatic tail; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A soft tissue density nodule, approximately 0.9 cm in diameter, was found adjacent to the spleen, and FDG uptake was normal.
Both kidneys were normal in shape and size, with punctate dense shadows in both renal calyces; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was adequately distended, with slight thickening of the gastric antrum wall and mildly increased FDG uptake (SUVmax = 1.9).
Intestinal distension was unsatisfactory, with no local masses observed, and FDG uptake was normal.
The prostate was enlarged with an irregular soft tissue mass, approximately 8.0*6.1cm in size, containing calcifications.
FDG uptake was unevenly increased, with SUVmax=5.8.
The left seminal vesicle was involved, with thickening of the adjacent posterior bladder wall.
Multiple soft tissue nodules were found in the surrounding fat spaces, pelvic floor, mesentery, and bilateral iliac vessels, the largest with a short diameter of approximately 2.1cm, showing increased FDG uptake, with SUVmax=5.5.
Calcification of the right testicular tunica vaginalis was present, and the left inguinal canal was widened, containing fat density shadows.
Overall bone density was decreased, but the spinal alignment was normal, with osteophyte formation at the vertebral margins in some areas, multiple intervertebral disc bulges, and flattening of the T11 vertebral body.
Patchy high-density shadows were present in the right iliac bone, and focal bone destruction with increased FDG uptake was observed in the left scapula, with SUVmax=2.2.
Localized increased FDG uptake was observed in the left iliac bone, with SUVmax=1.8.

Impression

1. a. Benign prostatic hyperplasia with calcification, prostatic mass with increased FDG metabolism, consistent with prostate cancer presentation, invading the left seminal vesicle and bladder; multiple metastatic lesions in the surrounding fat space, pelvic floor, mesentery, and bilateral iliac vessels. b. Left scapular metastasis is highly probable; left iliac bone metastasis is pending, right iliac bone island is highly probable, please confirm with contrast-enhanced MRI.

2. Bilateral chronic inflammatory nodules are highly probable, CT follow-up is recommended. Left upper lobe contains air sac cavity. A few post-inflammatory remnants in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Gallstones. Accessory spleen. Calcification lesion in the pancreatic tail.

4. Bilateral kidney stones. Calcification lesion in the right testicular tunica vaginalis. Left inguinal hernia.

5. Chronic inflammatory changes in the lower esophagus and gastric antrum, please confirm with endoscopy.

6. Osteoporosis, degenerative changes in the spine, multiple intervertebral disc bulges, and T11 vertebral body wedging.

7. Age-related brain abnormalities, deep lacunar infarcts, and white matter degeneration; please correlate with MRI. Chronic inflammation of the left maxillary sinus. High-density nodule below the left eyeball; please correlate with clinical findings.

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.
