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: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma and no abnormal FDG uptake.
There was no widening of the ventricles, sulci, fissures, or cisterns, and no abnormalities in local density or FDG uptake; the midline structure was not shifted.
No significant bone destruction was observed in the skull, and FDG uptake was normal.
The bilateral eyeballs had normal morphology and outline, with clear retrobulbar structures and no abnormal FDG uptake.
Slight thickening of the mucosa in the left ethmoid sinus was observed, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal wall was observed; the bilateral pharyngeal recesses were symmetrical, and FDG uptake was increased on both sides (SUVmax = 4.1).
The base of the tongue and both palatine tonsils were full, and FDG uptake was physiological.
The morphology and structure of the laryngopharynx are normal, and the parapharyngeal space is clear.
The size, shape, and density of the bilateral parotid and submandibular glands are normal, and FDG uptake is physiological.
The thyroid gland is full and of uneven density, with increased FDG uptake (SUVmax = 7.1).
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, or submental region; FDG uptake is normal.
A round, pure ground-glass nodule with indistinct borders, approximately 0.3 cm in diameter, is seen in the subpleural region of the apical segment of the right upper lobe; FDG uptake is normal.
Two small solid nodules are seen in the medial segment of the right middle lobe and the oblique fissure of the left lung; the former is larger, approximately 0.3 cm in diameter, and FDG uptake is normal.
A few patchy and linear shadows are seen in the right middle lobe; a punctate calcification and a small, round, lucid shadow with approximately 0.5 cm in diameter are seen in the right upper lobe; FDG uptake is normal.
Slight thickening of the pleura bilaterally, with no obvious pleural effusion.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions, and FDG uptake was not significantly increased.
The heart size was normal.
The breasts showed dense fibrous glands, and FDG uptake was normal.
Small, flat lymph nodes were visible in both axillae, with the hilum visible; some lymph nodes on the left side showed increased FDG uptake (SUVmax = 2.2).
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A small, round, low-density lesion approximately 0.5 cm in diameter was seen in the upper segment of the right posterior lobe of the liver, and punctate calcifications were seen in the lower segment of the right anterior lobe of the liver; FDG uptake was normal.
No dilation of the intrahepatic or extrahepatic bile ducts was observed.
Post-cholecystectomy changes were noted; FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct is not widened, and FDG uptake is normal.
The spleen is of normal shape and size, with no abnormalities in density or FDG uptake.
Both adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG uptake.
Both kidneys are of normal shape and size, with no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormalities in FDG uptake.
The renal pelvis, calyces, and ureters are not widened, and no positive stones are observed locally.
The bladder is adequately filled, with no obvious localized thickening or mass in the wall, and no positive stones are observed within the bladder.
A soft tissue nodule and mass are seen in each of the bilateral adnexa.
The left and right lesions measure approximately 2.42.01.8cm and 4.63.13.6cm respectively, with relatively homogeneous density.
No obvious necrosis or calcification is observed within them.
FDG uptake is increased, with SUVmax=16.5.
The right lesion has indistinct borders and is not clearly demarcated from the right margin of the adjacent uterus.
A soft tissue mass is seen in the rectouterine pouch, with relatively clear borders, measuring approximately 5.04.52.1cm.
The density is relatively homogeneous, with increased FDG uptake (SUVmax=21.9).
Its demarcation from the posterior margin of the cervix, sigmoid colon, and the mass in the right adnexa is indistinct.
Multiple lymph nodes were observed on the right side of the rectum, in the presacral space, on both sides of the pelvic wall, beside the left external iliac vessels, beside both common iliac vessels, beside the abdominal aorta, and behind the right diaphragmatic crus.
Some were enlarged and swollen, with the largest located retroperitoneally, measuring approximately 2.6 1.5 cm.
FDG uptake was increased, with SUVmax = 9.8.
No significant effusion was observed in the abdominopelvic cavity.
Localized nodular bulges were seen on the surface of the uterus, with isodense to slightly hyperdense nodular shadows, some protruding beyond the outline.
The largest had a long diameter of approximately 1.5 cm, and some showed increased FDG uptake, with SUVmax = 4.1.
The remaining intestinal contents were not satisfactorily filled, with no local masses observed, and FDG uptake was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was normal.
The stomach was well-filled, with slight thickening of the gastric wall in the antrum, and increased FDG uptake, with SUVmax = 2.8.
The spinal sequence is normal, with osteophyte formation at the margins of some vertebral bodies and L3/4 intervertebral disc bulging.
No abnormal uptake was observed in FDG.

Impression

1. a. Multiple space-occupying lesions in the bilateral adnexa and rectouterine pouch, multiple enlarged and swollen lymph nodes in the abdominopelvic region (as described above), increased FDG metabolism. The above suggests malignancy, with ovarian cancer and multiple metastases being highly probable. Metastatic tumors should be ruled out. Some lesions have unclear boundaries with the uterus and adjacent intestines; please consult pathology. b. Uterine fibroids with partial degeneration.

2. a. Chronic inflammatory ground-glass nodules or atypical adenomatous hyperplasia in the apical segment of the right upper lobe; chronic inflammatory solid nodules in the medial segment of the right middle lobe and the oblique fissure of the left lung. Please repeat HRCT. b. A few post-inflammatory remnants in the right middle lobe; calcifications and small air-filled cysts in the right upper lobe. c. Bilateral breast proliferative changes; reactive hyperplasia of small axillary lymph nodes bilaterally.

3. Thyroid gland is full and uneven in density with increased FDG metabolism, suggesting inflammatory uptake; please follow up with ultrasound.

4. Small cysts and calcifications in the right lobe of the liver. Post-cholecystectomy changes.

5. Manifestations of chronic gastritis.

6. Degenerative changes in the spine, L3/4 intervertebral disc bulge.

7. No obvious abnormalities seen on cranial scintigraphy. Minor chronic inflammation of the left ethmoid sinus. Physiological uptake in the nasopharynx.

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.
