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 and patchy slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Enlargement 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; bilateral lenses were not clearly visualized; no other obvious abnormalities were observed.
Slight thickening of the left maxillary sinus was observed; the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
Nasal septum was deviated; the nasopharyngeal wall was not thickened; FDG uptake was normal; bilateral pharyngeal recesses were symmetrical; the openings of the Eustachian tubes were not narrowed; the structures of the infratemporal and pterygopalatine fossae were normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed bilaterally in the neck.
Enlarged lymph nodes were present in the left supraclavicular fossa, the largest measuring approximately 2.2*1.3cm, with increased FDG uptake (SUVmax=4.2).
Increased lung markings were observed bilaterally, with multiple solid nodules in both lungs, with clear borders; the largest, located in the medial segment of the right middle lobe, measured approximately 0.9cm in diameter, with no abnormal FDG uptake.
Multiple air-filled cavities were observed bilaterally, along with scattered calcifications and linear foci; FDG uptake was normal.
A small amount of pleural effusion was observed bilaterally.
Multiple lymph nodes were observed in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest had a short diameter of approximately 1.2cm, with increased FDG uptake (SUVmax=4.2).
The heart is enlarged, with pericardial effusion and a cardiac chamber density lower than that of the myocardium.
Calcification is present in some arterial walls (including the coronary arteries).
Bilateral gynecomastia is present.
The esophagus shows no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver is normal in shape and size, with smooth borders, no widening of the hepatic fissure, and small cystic lesions (approximately 0.5 cm in diameter) within the liver; FDG uptake is normal.
The main portal vein is not significantly widened, and there is no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size.
A cystic lesion, approximately 5.6 cm in diameter, is present in the left kidney, with absent FDG uptake.
Bilateral renal pelvis and upper ureter are dilated with fluid accumulation, but FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
The stomach is poorly distended, with a considerable amount of residual contents.
No significant thickening of the stomach wall is observed, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no significant thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is enlarged, with a long diameter of approximately 5.1 cm, containing punctate dense shadows.
An irregular, patchy soft tissue density shadow is seen on the right side of the prostate, with indistinct borders and increased FDG uptake (SUVmax = 4.2), covering an area of approximately 5.8*3.3 cm, with indistinct demarcation from the adjacent bladder.
Multiple enlarged lymph nodes are visible near the right iliac vessels and in the retroperitoneum, the largest being approximately 3.0*2.2 cm in size, also showing increased FDG uptake (SUVmax = 5.3).
Increased muscle uptake throughout the body is observed.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
A high-density lesion is present on the right side of the sacrum, approximately 1.2 cm in diameter.
Local cortical bone distortion is observed on the right clavicle, with no abnormalities in FDG metabolism.
No abnormalities are seen on limb imaging.
Uneven FDG metabolism is observed in the bone marrow.

Impression

1. Benign prostatic hyperplasia with calcification; a mass on the right side of the prostate with increased FDG metabolism; multiple enlarged lymph nodes in the right iliac vessels, retroperitoneum, and left supraclavicular fossa with increased FDG metabolism. Malignancy is suspected, with prostate cancer with multiple metastases being the primary consideration. Please confirm with pathology.

2. Chronic inflammatory nodules in both lungs; CT follow-up is recommended to rule out other possibilities. Bilateral emphysema. Scattered post-inflammatory lesions in both lungs. Reactive hyperplasia of hilar lymph nodes bilaterally; mediastinal lymph node metastasis to be ruled out; follow-up is recommended. Small amount of pleural effusion bilaterally. Pericardial effusion. Anemia changes; calcification of some arterial walls (including coronary arteries). Bilateral gynecomastia.

3. Small liver cyst. Left renal cyst. Bilateral dilated effusion of the renal pelvis and upper ureter.

4. Degenerative changes in the spine, L4/5 and L5/S1 disc bulges. Right sacral islet. Possible old fracture of the right clavicle; please refer to medical history.

5. Age-related brain abnormalities, deep cerebral ischemia; please follow up with MRI. Chronic inflammation of the 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.
