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, 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; local density and FDG uptake were normal, and there was no midline shift.
The bilateral eyeballs had normal morphology and outline; the retrobulbar structures were clear, and FDG uptake was normal.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The soft tissue of the nasopharyngeal walls showed no significant thickening; the bilateral pharyngeal recesses were symmetrical, and FDG uptake was normal.
The base of the tongue and both palatine tonsils were full, and FDG uptake was physiological.
The laryngopharynx had normal morphology and structure, and the parapharyngeal space was clear.
The bilateral parotid and submandibular glands showed no abnormalities in size, shape, or density, and FDG uptake was physiological.
Thyroid gland is normal in shape and size, with no obvious abnormal density shadows, and FDG uptake is normal.
Multiple small, flat lymph nodes are visible bilaterally in the posterior cervical subcutaneous tissue, deep cervical space, submandibular region, and submental region, the largest with a short diameter of approximately 0.6 cm, showing increased FDG uptake (SUVmax = 3.2).
No obvious abnormal density shadows are seen in the lung parenchyma bilaterally, and FDG uptake is normal.
No obvious thickening of the pleura bilaterally, and no obvious pleural effusion bilaterally.
No obvious enlarged lymph nodes are seen in the hilar region and mediastinum bilaterally, and FDG uptake is not significantly increased.
The heart size is normal.
The fibrous glands in both breasts are dense, and FDG uptake is normal.
The liver is normal in shape and size, with smooth liver margins and no widening of the hepatic fissure.
No obvious abnormal density shadows are seen in the liver parenchyma, and FDG uptake is normal.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, the gallbladder wall was not thickened, and no positive stones or obvious masses were observed.
FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces were clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct was not widened, and FDG uptake was normal.
The spleen was of essentially normal shape and size, with no abnormalities in density or FDG uptake.
The bilateral adrenal glands showed no abnormalities in shape, size, or density, and local FDG uptake was normal.
The bilateral kidneys were of normal shape and size, with no obvious abnormal density shadows in the renal parenchyma and no obvious abnormalities in FDG uptake.
No widening of the bilateral renal pelvis, calyces, or ureters was observed, and no positive stones were observed locally.
The bladder was poorly filled, with no obvious localized thickening or masses in the wall, and no positive stones were observed within the lumen.
The uterus is normal in shape and size, with increased FDG uptake in the uterine cavity (SUVmax = 5.6).
A patchy low-density lesion with relatively clear borders, approximately 3.5 cm in long diameter, is seen in the left adnexa, with increased local FDG uptake (SUVmax = 7.1).
The esophagus is not dilated, and the wall is not significantly thickened or lumped; FDG uptake is not increased.
The stomach is well-filled, with no obvious localized thickening of the gastric wall; FDG uptake is normal.
The intestines are not sufficiently full, with no localized masses; FDG uptake is normal.
A large, multilocular cystic mass was observed in the abdominopelvic cavity.
The lower margin was indistinct from the right adnexa, while the surrounding intestinal tract was clearly defined.
The mass measured approximately 20.6 10.3 26.0 cm.
The CT value of the large cystic fluid within the mass was approximately 9 and 17 HU.
Nodular foci of soft tissue were observed attached to the cyst wall and septa, with increased FDG uptake (SUVmax = 8.9).
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneum, and FDG uptake was normal.
A small amount of pelvic effusion was present.
The spinal alignment was normal, with no obvious bone structural abnormalities, and FDG uptake was normal.

Impression

1. A large, multilocular cystic-solid lesion in the abdominopelvic cavity, with increased FDG metabolism in the solid portion, is highly suggestive of a right ovarian cystadenoma with local malignant transformation; please confirm with pathology.

2. Physiological uptake in the uterine cavity; physiological cyst in the left adnexal region; please confirm with ultrasound follow-up. Small amount of pelvic effusion.

3. No obvious abnormalities seen on cranial scintigraphy. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
