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, a whole-body PET/CT scan was performed.
The whole-body scan showed: a slightly high-density mass at the right middle cranial fossa floor, approximately 3.0 3.2 cm in size, containing irregular calcified foci.
FDG metabolism was slightly elevated, with SUVmax = 2.5.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
No widening was observed in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were normal, and the parapharyngeal spaces were clear with no abnormal 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 were normal.
Postoperative changes were observed in the left thyroid lobe; the right lobe was normal in shape and size, but its density was somewhat uneven, and FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A solid micronodule, approximately 0.2 cm in long diameter, with clear borders, was seen in the posterior segment of the right upper lobe; FDG metabolism was normal.
A few linear shadows were seen in the remaining lungs; FDG uptake was normal in all of them.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
No esophageal dilation was seen; no significant thickening or mass was seen in the esophageal wall, and FDG uptake was normal.
The bilateral breasts were normal, and FDG metabolism was normal.
The liver's shape and size are normal, with smooth borders and no widening of the hepatic fissure.
Low-density lesions are present in the liver capsule area, with increased FDG uptake (SUVmax = 6.7, the largest being approximately 3.3 cm in length).
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is absent post-operatively.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
Several slightly low-density lesions are present in the spleen, the largest being approximately 1.2 cm in length, with no abnormal FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Both adrenal glands are enlarged, with no abnormal FDG uptake.
Stomach distension is poor, with no obvious thickening of the gastric wall, and no significant abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
A cystic low-density lesion measuring approximately 4.0 3.1 cm is seen on the left side of the uterus, with localized nodular consolidation and increased FDG metabolism (SUVmax = 4.2).
The bilateral adnexa are full, with unclear structures, and increased FDG metabolism (SUVmax = 8.9).
The greater omentum, mesentery, and pelvic floor are extensively thickened, presenting as multiple flocculent, nodular, and patchy masses, with increased FDG metabolism (SUVmax = 7.9).
Several enlarged lymph nodes are seen in the portal vena cava space and retroperitoneum, the largest with a short diameter of approximately 1.5 cm, with increased FDG metabolism (SUVmax = 5.3).
Fluid accumulation is present in the abdominal and pelvic cavities.
Bladder fullness is normal, no obvious positive stones are seen inside.
Spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 disc bulging.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Bilateral adnexal regions are full, structures are not clearly visible, FDG metabolism is increased, suggesting a high probability of malignancy, either primary or metastatic. Please combine with enhanced MRI for comprehensive analysis. b. Extensive implantation metastases in the abdominopelvic cavity. Liver metastasis is possible, and capsular metastasis involving the liver cannot be ruled out. Portocaval space and retroperitoneal lymph node metastases. Abdominal and pelvic effusions. c. Cystic low-density lesion on the left side of the uterus, with local nodular consolidation and increased FDG metabolism, suggesting possible cystic degeneration of uterine fibroids, with local malignancy to be ruled out. Please combine with enhanced MRI for comprehensive analysis. d. Splenic angioma is highly probable, ultrasound follow-up is recommended. Bilateral adrenal hyperplasia.

2. Right middle cranial fossa floor mass, mildly increased FDG metabolism, suggesting a high probability of meningioma with calcification, with chondrosarcoma to be ruled out. Further enhanced MRI examination is recommended.

3. Chronic inflammatory nodules (solid) in the posterior segment of the right upper lobe. A few chronic inflammations and old lesions in both lungs. Some arterial wall calcifications.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

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.
