Whole-body 18F-FDG PET/CT scan in a patient with Colon 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 a few patchy low-density shadows in the deep brain regions; no significant abnormalities were observed in FDG uptake.
Widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; no abnormalities were observed in FDG uptake.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; no abnormalities were observed in FDG uptake.
Scattered solid nodules with clear borders, approximately 0.3-0.5 cm in long diameter, with normal FDG uptake.
Thickening of the interlobular septa with cystic lucent shadows in both lungs, and multiple linear and patchy high-density shadows in both lungs.
No pleural thickening, and no pleural effusion or pneumothorax.
Multiple supraclavicular and mediastinal lymph nodes bilaterally, the largest approximately 0.9 cm in short diameter, with increased FDG metabolism (SUVmax = 4.8).
Calcification of some arterial walls (including coronary arteries).
Cardiac enlargement.
No esophageal dilatation, but increased FDG metabolism in the middle and lower esophagus (SUVmax = 4.9).
Disproportionate liver shape with irregular borders, widened hepatic fissures, and multiple nodular FDG-enhanced areas around the liver and at the porta hepatis, the largest measuring approximately 1.4 x 0.9 cm (SUVmax = 6.7).
Calcification in the right lobe of the liver.
No significant widening of the main portal vein, and no dilatation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened.
Local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen was normal in shape and size, with a few calcifications within the spleen and nodular FDG metabolism around the spleen, with a long diameter of approximately 0.6 cm and an SUVmax of 4.1.
Both kidneys showed mild atrophy.
A dense shadow with a long diameter of approximately 0.3 cm was seen in the right kidney, and a low-density lesion with clear borders and no FDG uptake was seen in the left kidney, with a diameter of approximately 3.0 cm.
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 poorly distended, with no obvious thickening of the stomach wall and no obvious abnormality in FDG uptake.
Intestinal distension was poor.
Soft tissue shadows with multiple calcifications in the sigmoid colon, measuring approximately 2.1*1.3cm, were observed in the intestinal wall, with increased FDG metabolism (SUVmax = 12.2).
Multiple nodules with increased FDG metabolism were found in the abdominopelvic cavity (SUVmax = 9.6, the largest approximately 2.0cm in length), involving adjacent intestinal walls.
Soft tissue shadows with increased FDG metabolism (SUVmax = 6.6) were seen in the left inguinal region.
The prostate was of normal size and homogeneous density, with no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
Calcifications and fluid accumulation were observed in the right testicular tunica vaginalis.
Several soft tissue nodules were seen in the right lower quadrant of the abdominal wall, the largest approximately 1.6*1.0cm, with increased FDG metabolism (SUVmax = 12.2).
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Increased local FDG metabolism in the soft tissues surrounding the right hip joint (SUVmax = 5.9).
Decreased bone density throughout the body; flattening of the T10 vertebral body with osteophyte formation at some vertebral margins.
Calcification of the nuchal ligament.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. Multiple peritoneal metastases in the abdominopelvic cavity (including perihepatic, hilar, and perisplenic areas); right lower abdominal wall metastasis; left inguinal region metastasis. b. A mass in the sigmoid colon with increased FDG uptake, suggestive of malignancy, most likely colon cancer; please follow up with colonoscopy.

2. Liver cirrhosis. Calcification in the right lobe of the liver. A few calcifications in the spleen.

3. Scattered chronic inflammatory nodules in both lungs; please follow up with CT scan. Interstitial lung changes with emphysema in both lungs. Chronic inflammation and sequelae in both lungs. Reactive hyperplasia of bilateral supraclavicular and mediastinal lymph nodes.

4. Cardiac enlargement. Calcification of some arterial walls (including coronary arteries); please follow up with coronary CTA.

5. Highly probable inflammatory uptake in the middle and lower esophagus; please follow up with gastroscopy.

6. Mild renal atrophy in both kidneys. Left renal cyst. Right renal calculus. Calcification and hydrocele in the right testicular tunica vaginalis.

7. Osteoporosis. Compression changes in the T10 vertebral body. Spinal degeneration. Right hip periarthritis.

8. A few ischemic foci deep in the brain, age-related brain changes.

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.
