Whole-body 18F-FDG PET/CT scan in a patient with Ovarian 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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
A small cystic lesion was seen in the left maxillary sinus, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Partial atelectasis in the left lower lobe; a soft tissue nodule measuring approximately 1.3 0.8 cm was seen near the diaphragm in the left lower lobe, with increased FDG metabolism (SUVmax = 5.6); several small solid nodules were observed in the remaining lungs, with a long diameter of approximately 0.2?.4 cm and clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
A small amount of pleural effusion was observed bilaterally; multiple nodular FDG-enhanced areas were observed in the bilateral pleura (SUVmax = 5.9).
Several slightly enlarged lymph nodes were seen in the left hilum, the largest with a short diameter of approximately 0.5 cm; FDG metabolism was increased (SUVmax = 5.9).
The cardiac silhouette was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
Bilateral mammary glands showed dense fibroadenomas, with physiological FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant 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.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG uptake is normal.
Bilateral adrenal glands show no obvious abnormalities on contrast imaging.
Stomach distension is poor, with no obvious thickening of the gastric wall, and FDG uptake is normal.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Two cystic-solid masses were observed in the bilateral adnexa, the right one being slightly larger, measuring approximately 7.2 4.1 cm.
The solid portion showed increased FDG metabolism (SUVmax = 11.4).
Multiple flocculent and nodular soft tissue masses were observed in the greater omentum, mesentery, right paracolic gutter, subcapsular region of the liver and spleen, left diaphragmatic crura, sigmoid mesentery, pelvic floor fascia, and rectouterine pouch.
The largest mass was approximately 5.3 3.5 cm, showing increased FDG metabolism (SUVmax = 12.8).
Multiple enlarged lymph nodes were observed in the bilateral pelvic walls, adjacent to the bilateral external iliac vessels, para-aortic region, right renal hilum, cardiophrenic angle, and left internal mammary chain.
The largest lymph node had a short diameter of approximately 1.8 cm, showing increased FDG metabolism (SUVmax = 13.6).
A small amount of fluid was present in the abdominal and pelvic cavities.
An intrauterine device (IUD) was observed in the uterine cavity.
The bladder was generally full, and no obvious positive stones were observed within it.
The spinal alignment is normal, with minor osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Bilateral adnexal region cystic-solid lesions, with increased FDG metabolism in the solid portion, suggestive of malignancy, most likely ovarian cancer; please correlate with clinicopathology. b. Multiple peritoneal seeding metastases in the abdominopelvic cavity. Multiple lymph node metastases in the bilateral pelvic walls, retroperitoneum, cardiophrenic angle, and left internal mammary chain. Bilateral pleural metastases. Small amount of effusion in the abdomen and pelvis. c. Soft tissue nodule near the diaphragm in the left lower lobe, with increased FDG metabolism, highly suggestive of metastasis.

2. Several small chronic inflammatory nodules (solid) in both lungs are possible; CT scan is recommended to rule out metastasis. A few chronic inflammations and old lesions in both lungs. Reactive hyperplasia of the left hilar lymph nodes is possible; follow-up is recommended. Small amount of pleural effusion in both cavities, with partial atelectasis in the left lower lobe.

3. Bilateral breast proliferative changes.

4. Mild osteophyte formation in the cervical, thoracic, and lumbar spine. L4/5 and L5/S1 intervertebral disc bulge.

5. No abnormalities found on cranial scintigraphy. Submucosal cyst 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.
