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: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
Increased soft tissue shadows were observed in the pituitary region, with increased FDG uptake (SUVmax = 10.4).
The eyeballs were symmetrical, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal walls 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 normal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with uniform density; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Several solid micronodules are present in both lungs, approximately 0.2-0.4 cm in long diameter, with clear borders; some show mildly increased FDG metabolism (SUVmax = 1.6).
A few punctate and linear lesions are also seen in both lungs; FDG metabolism is normal.
No pleural thickening is observed bilaterally; there is no pleural effusion or pneumothorax.
Several lymph nodes are seen in the bilateral hilar regions, pretracheal spaces, aortic windows, and below the carina; the largest has a short diameter of approximately 0.6 cm; FDG metabolism is increased (SUVmax = 3.6).
The cardiac silhouette is normal.
Some arterial walls show calcification (including coronary arteries).
The esophagus is not dilated; the wall is not significantly thickened or swollen; FDG uptake is 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 no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureter.
FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is full in shape, with a transverse diameter of approximately 5.1 cm.
The density within the gland is uneven, more pronounced on the left side.
FDG metabolism is increased, with SUVmax=4.2.
The boundary between the prostate and the left seminal vesicle and adjacent bladder wall is unclear, involving the distal left ureter, resulting in dilation and hydronephrosis of the ureter and renal pelvis.
Slightly enlarged lymph nodes are seen on the left pelvic wall, with a short diameter of approximately 0.6 cm.
FDG metabolism is increased, with SUVmax=2.6.
No obvious fluid accumulation is seen in the abdomen or pelvic cavity.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
The intertrochanteric density of the right femur is uneven, FDG metabolism is increased, and SUVmax = 3.6.

Impression

1. a. Benign prostatic hyperplasia (BPH), with uneven glandular density and increased FDG metabolism, consistent with prostate cancer, involving the left seminal vesicle and adjacent bladder wall, and the distal left ureter, leading to hydronephrosis of the ureter and renal pelvis. b. Possible reactive hyperplasia of left pelvic wall lymph nodes, metastasis to be ruled out. c. Uneven density of the right intertrochanteric region of the femur, increased FDG metabolism; follow-up is recommended to rule out metastasis.

2. Pituitary lesion, increased FDG uptake, suggestive of pituitary tumor; enhanced MRI is recommended for further examination to rule out other possibilities.

3. a. Possible several chronic inflammatory micronodules in both lungs, some metastasis to be ruled out; regular HRCT follow-up is recommended for comparison. A few chronic inflammations and old lesions in both lungs. b. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Some arterial wall calcification (including coronary arteries).

4. Cervical, thoracic, and lumbar spondylosis. L4/5 and L5/S1 intervertebral disc bulges.

5. A few ischemic lesions in the deep bilateral cerebral regions, indicative of age-related encephalopathy.

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.
