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

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: Normal brain morphology and structure, with patchy, slightly low-density lesions in the deep brain regions, and patchy/stripy low-density lesions in the bilateral basal ganglia, indicating absent FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal, and there was no midline shift.
The eyes were symmetrical with no obvious abnormalities.
Thickening of the mucosa of the right ethmoid sinus and left maxillary sinus was observed, while the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and the palatine tonsils were symmetrical, showing physiological FDG uptake.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with uniform density, and no abnormal FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
Multiple solid nodules are present in both lungs, the largest being approximately 0.4 cm in diameter.
No abnormal FDG uptake was observed.
A few air-filled cavities are present in the upper lobes of both lungs.
Scattered calcifications and linear lesions are present in both lungs.
No abnormal FDG uptake was observed.
Pleural thickening is present bilaterally, but there is no pleural effusion or pneumothorax.
Lymph nodes are visible in the hilar region, pretracheal region, posterior vena cava region, aortic window, para-aortic arch region, and subcarinal region.
The largest has a short diameter of approximately 1.1 cm, with increased FDG uptake (SUVmax = 5.8).
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the wall is not significantly thickened or swollen.
No increased FDG uptake was observed.
The liver is normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions are present in the liver, the largest being approximately 4.7 cm in long diameter, with absent FDG uptake.
The main portal vein is not significantly widened.
The gallbladder is absent, with compensatory dilation of the common bile duct.
The pancreas is normal in shape but decreased in density; 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; a cystic lesion is present in the right kidney parenchyma, approximately 1.0 cm in diameter; FDG metabolism is normal; the renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no significant abnormalities on contrast imaging.
The stomach is adequately distended, with slight thickening of part of the gastric wall; FDG uptake is increased, SUVmax = 3.6.
The intestines are not adequately distended; no local masses are observed; continuous FDG uptake is increased in part of the intestinal tract, SUVmax = 5.3.
An irregular soft tissue mass of the prostate, with indistinct borders, measures approximately 6.7*5.2*5.8cm, containing calcifications.
FDG uptake is unevenly increased, with an SUVmax of 6.4.
The boundary between the mass and the adjacent bladder and rectum is indistinct.
Multiple enlarged lymph nodes are present in the bilateral pelvic walls, bilateral iliac vessels, and retroperitoneum, some fused into clusters, the largest with a short diameter of approximately 3.3cm.
FDG uptake is unevenly increased, with an SUVmax of 4.6.
Generalized bone density is decreased.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, posterior slippage of the L2 and L3 vertebral bodies, and multiple lumbar intervertebral disc bulges with pneumoconiosis and degeneration.
FDG uptake of the entire skeleton is normal.
Visualization of both lower extremities is normal.

Impression

1. a. Irregular prostatic lesion with elevated FDG metabolism, highly suggestive of prostate cancer; please combine PSA and MRI for comprehensive analysis; benign prostatic hyperplasia with calcification. b. Multiple lymph node metastases in bilateral pelvic walls, bilateral iliac vessels, and retroperitoneum are highly probable; lymphoma to be ruled out.

2. a. Chronic inflammatory micronodules in both lungs; CT follow-up is recommended to rule out other complications. Mild emphysema in the upper lobes of both lungs; chronic inflammation and post-inflammatory remnants in both lungs. b. Chronic inflammatory lymph nodes in the hilar and mediastinal regions of both lungs. Pleural thickening bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Multiple liver cysts. Post-cholecystectomy changes; compensatory dilatation of the common bile duct. Fatty infiltration of the pancreas. Right renal cyst.

4. Chronic inflammatory changes in part of the gastric wall and intestinal tract; please combine endoscopic follow-up.

5. Osteoporosis; degenerative changes in the spine; posterior slippage of L2 and L3 vertebral bodies; multiple bulging lumbar intervertebral discs with pneumothorax and degeneration.

6. Age-related brain abnormalities, deep lacunar infarcts, bilateral basal ganglia softening, and chronic inflammation of the right ethmoid sinus and left maxillary sinus.

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.
