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, and resting, 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; and 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, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; 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.
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 uniform density; and FDG uptake was normal.
Several small lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
Lung markings were clear bilaterally; a few fibrous strands were visible in the right upper lung; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Cardiac findings were normal.
This was after PICC line insertion.
The esophagus was not dilated; the esophageal wall was not significantly thickened or swollen; FDG uptake was normal.
Both breasts were relatively dense; FDG metabolism was normal.
The liver's shape and size were normal; liver margins were smooth; the hepatic fissure was not widened; no significant abnormal density shadows were observed in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal; the gallbladder wall was not thickened; local FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureter, and no obvious abnormalities in FDG uptake.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Post-colon cancer surgery, in the left abdominal colostomy: dense suture shadows are seen in the presacral surgical area, with no obvious thickening of the local intestinal wall and no abnormalities in FDG uptake.
A mixed cystic-solid density shadow is seen in the right adnexal region, with indistinct borders, measuring approximately 5.4*3.4cm.
The solid component shows increased FDG metabolism (SUVmax=9.0), and the boundary between the edge and the post-rectal blind end is unclear.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism is normal.
A small amount of effusion is seen in the pelvic cavity.
An intrauterine device was observed in the uterine cavity, but FDG uptake was not abnormally increased.
The bladder was generally full, and no obvious positive stones were observed.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebrae.
L4/5 and L5/S1 disc herniation were observed, but FDG uptake was not abnormal.
Systemic bone marrow FDG metabolism was normal.

Impression

1. Post-colon cancer surgery: a. No obvious signs of tumor recurrence at the anastomosis site. Pelvic effusion. b. Cystic-solid mass in the right adnexal region, with increased FDG metabolism in the solid component, suggesting a high probability of ovarian neoplasia (metastasis to be ruled out). The boundary with the post-rectal blind end is unclear; please combine laboratory tests and enhanced MRI for comprehensive judgment.

2. A few old lesions in the right upper lung.

3. Mild osteophyte formation in some vertebral bodies, L4/5 and L5/S1 disc herniation.

4. No obvious abnormalities seen on brain 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.
