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; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally; and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region; FDG metabolism was normal.
Scattered ground-glass nodules with clear borders, approximately 0.5-0.6 cm in length, were observed in the lateral basal segment of the left lower lobe and the apical segment of the right upper lobe.
A small solid nodule with clear borders, approximately 0.3 cm in length, was also observed in the posterior segment of the right upper lobe.
FDG uptake was normal.
A small amount of pleural effusion was present on the left side.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, and the wall was not significantly thickened or swollen.
FDG uptake was not increased.
Solid nodules were observed in both breasts, the larger one being on the right side, approximately 1.1 cm in diameter.
FDG metabolism was not significantly elevated.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
CT scan revealed scattered small low-density shadows within the liver parenchyma, approximately 0.2-0.3 cm in length, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
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 showed no abnormalities in shape, size, density, or FDG uptake.
Accessory splenic nodules were visible.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
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 abnormalities in FDG uptake.
The intestines were poorly distended, with increased FDG metabolism in the rectum and anal canal (SUVmax = 14.2).
This was post-hysterectomy.
The bladder was generally full, with no obvious positive stones.
The peritoneum around the liver and spleen, as well as the peritoneum in the abdominus and pelvis, was extensively thickened and blurred.
Multiple small lymph nodes were visible in the mesentery, with increased FDG metabolism (SUVmax = 6.1).
Pelvic effusion with irregular cystic-solid density lesions, affecting both adnexa, measuring approximately 6.7*3.4cm, with increased FDG metabolism at the periphery (SUVmax = 4.2).
Spinal alignment is normal, with some vertebral body margin osteophytes.
Nuchal ligament calcification is present.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A cystic-solid mass in the pelvic cavity with increased FDG metabolism at the periphery, suggesting a high probability of neoplastic lesions (metastasis is more likely than primary malignant ovarian tumors). Inflammatory lesions (tuberculosis) need to be ruled out. Please combine laboratory tests and clinicopathological examination. b. Pelvic effusion, extensive thickening and blurring of the perihepatic and splenic capsule and peritoneum in the abdominopelvic cavity, with multiple small lymph nodes visible in the mesentery, and increased FDG metabolism, suggesting extensive involvement of the pelvic and abdominal cavities. c. No obvious abnormal FDG metabolism was observed in the pancreas and biliary system (further CA19-9 and enhanced MRI follow-up are recommended).

2. Scattered ground-glass nodules in the lateral basal segment of the left lower lobe and the apical segment of the right upper lobe, with no increased FDG metabolism, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules. A small chronic inflammatory nodule in the posterior segment of the right upper lobe, please follow up with CT. Small amount of pleural effusion in the left side.

3. Bilateral solid breast nodules, with no increased FDG metabolism, suggestive of fibroadenomas, please combine with ultrasound follow-up.

4. Small hepatic cysts. Accessory spleen.

5. Increased FDG metabolism in the rectum and anal canal, likely due to inflammatory uptake; please confirm clinical findings and repeat colonoscopy to rule out the possibility of a low-lying tumor.

6. Partial vertebral osteophyte formation. Nuchal ligament calcification.

7. No obvious abnormalities found on cranial scintigraphy.

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.
