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 punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
The eyes were symmetrical bilaterally, with no obvious abnormalities.
Thickening of the mucosa of the bilateral ethmoid and maxillary sinuses was observed, but the mucosa of the remaining paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was slightly deviated, but the nasopharyngeal wall was not thickened; FDG uptake was normal.
The bilateral 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; FDG uptake was normal.
Increased FDG uptake was observed at the base of the tongue and bilateral palatine tonsils, with SUVmax = 10.5.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was full with uneven density; FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings were clear bilaterally; multiple solid nodules were present in both lungs, the largest approximately 0.4 cm in diameter; FDG uptake was normal.
A thick-walled cystic cavity, approximately 1.0 cm in diameter, was present in the posterior basal segment of the left lower lobe.
Scattered linear lesions were present in both lungs; FDG uptake was normal.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Calcification of some arterial walls was observed (including the coronary arteries).
The esophagus was not dilated; no significant thickening or mass was observed in the esophageal wall; FDG uptake was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
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.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with punctate dense shadows in the pancreatic body; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with a cystic lesion at the lower pole of the left kidney, approximately 2.7 cm in long diameter, and absent FDG uptake.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor, with thickening of the antral wall and increased FDG uptake (SUVmax = 5.4).
Intestinal distension is unsatisfactory, but intestinal uptake is physiological.
The prostate is enlarged, with a long diameter of approximately 4.4 cm, containing calcifications of uneven density and irregular soft tissue density shadows with indistinct borders, most prominent on the right peripheral side.
FDG uptake is increased (SUVmax = 6.9), involving the posterior wall of the bladder and seminal vesicles.
The posterior wall of the bladder is thickened with nodular protrusions, and FDG uptake is increased (FDG measurement is inaccurate due to urine influence) (SUVmax = 4.5).
Bilateral inguinal lymph nodes are visible, the largest with a short diameter of approximately 0.8 cm; FDG metabolism is normal.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, slight posterior displacement of the L4 vertebral body, and L4/5 intervertebral disc bulging.
No abnormalities were found in FDG metabolism throughout the bone marrow.

Impression

1. Benign prostatic hyperplasia with calcification; prostatic mass with increased FDG metabolism, consistent with prostate cancer, involving the posterior wall of the bladder and seminal vesicles, bladder mass to be ruled out. Reactive hyperplasia of bilateral inguinal lymph nodes.

2. Chronic inflammatory micronodules (solid) in both lungs. Cystic cavity in the posterior wall of the posterior basal segment of the left lower lobe, cystic lung cancer should be suspected, HRCT follow-up is recommended in 3-6 months. Scattered post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Pancreatic calcification. Left renal cyst.

4. Chronic inflammatory changes in the antrum of the stomach, please follow up with endoscopy.

5. Degenerative changes in the spine, slight posterior slippage of the L4 vertebral body, L4/5 intervertebral disc bulge.

6. Age-related brain, deep lacunar ischemic lesions in the brain. Chronic inflammation of both ethmoid sinuses and both maxillary sinuses. Inflammation of the base of the tongue and both palatine tonsils.

7. Nodular goiter; ultrasound follow-up is recommended.

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.
