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 significant abnormalities in FDG uptake.
The sulci, fissures, and cisterns were slightly widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally 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 parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland density is slightly decreased; a small, round, dense shadow is visible on the medial border of the left lobe, with increased FDG uptake (SUVmax = 2.6).
No significantly enlarged lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, or submental region; FDG metabolism is normal.
A pure ground-glass nodule with relatively clear borders and a long diameter of approximately 0.3 cm is visible in the anterior segment of the left upper lobe; FDG uptake is normal.
Scattered linear shadows are seen in both lungs; FDG uptake is normal.
No pleural thickening is seen bilaterally; there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette is normal.
Both breasts are relatively dense; FDG metabolism is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
The liver parenchyma showed a uniformly decreased density, and intrahepatic vessels were not clearly visualized.
A small cystic lesion, approximately 0.3 cm in long diameter, was observed in the left lateral lobe of the liver, with no abnormal FDG uptake.
Multiple nodules were observed in and beneath the liver capsule, the largest being approximately 3.7 2.2 cm located at the right lobe capsule margin, with increased FDG metabolism (SUVmax = 8.7).
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 and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and no obvious abnormal FDG uptake was observed.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A small, round, dense shadow is visible in the left kidney, and multiple punctate, dense shadows are visible in the right kidney.
No abnormal FDG uptake was observed.
No obvious abnormalities were observed on the right adrenal gland.
The left adrenal gland appears full and shows increased FDG uptake (SUVmax = 2.6).
No esophageal dilation, wall thickening, or mass was observed, and FDG uptake was not increased.
The stomach is poorly filled, and the wall is not significantly thickened; FDG uptake is not significantly abnormal.
Partially strip-shaped areas show increased FDG uptake (SUVmax = 3.4).
Focal increased FDG uptake is observed in the anal region (SUVmax = 11.2).
Irregular masses or clumps are seen in both adnexa.
The left mass is cystic-solid and larger, approximately 7.4 6.1 cm, while the right mass is approximately 4.9 3.5 cm.
FDG metabolism is increased (SUVmax = 12.2), and the adjacent uterus is involved with indistinct borders.
Multiple patchy and nodular shadows were observed in the pelvic peritoneum, bilateral paracolic gutter, and mid-abdomen mesentery, with increased FDG metabolism (SUVmax = 16.7).
Multiple lymph nodes were observed in the retroperitoneum and bilateral inguinal regions, the largest with a short diameter of approximately 0.5 cm, some with increased FDG uptake (SUVmax = 1.2).
The bladder was generally full, and no obvious positive stones were observed.
No significant effusion was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes, L4/5 disc bulging, and L5/S1 disc herniation, but FDG uptake was normal.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Bilateral adnexal region lesions with increased FDG metabolism, suggestive of ovarian cancer involving the uterus; please correlate with clinicopathology. Multiple peritoneal seeding metastases. Liver metastases to be ruled out; enhanced MRI analysis recommended. b. Multiple reactive hyperplasia of retroperitoneal and bilateral inguinal lymph nodes.

2. a. Pure ground-glass nodule in the anterior segment of the left upper lobe, normal FDG metabolism, suggestive of atypical adenomatous hyperplasia or inflammatory nodule; annual HRCT follow-up recommended. b. A few post-inflammatory lesions in both lungs.

3. Fatty liver, small cyst in the left lateral lobe of the liver. Small kidney stone in the left kidney, multiple microlithiasis in the right kidney. Left adrenal hyperplasia.

4. Increased FDG uptake in some colonic strips, suggestive of inflammation or physiological uptake. Focal increased FDG uptake in the anal region, suggestive of hemorrhoids.

5. Slightly decreased thyroid density with calcification in the left lobe and increased FDG uptake suggest thyroiditis; ultrasound and thyroid function tests are recommended for follow-up.

6. Spinal osteophyte formation. L4/5 disc bulge, L5/S1 disc herniation.

7. Mild age-related brain changes.

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.
