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 an increased cerebrospinal fluid density shadow (approximately 3.5*1.3cm) in the left temporal pole, but FDG uptake was absent.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal, and midline structure shift was normal.
The bilateral eyeballs had normal morphology and outlines, clear retrobulbar structures, symmetrical optic nerves, and no abnormal FDG uptake.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; there was no narrowing of the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with slightly heterogeneous density; FDG uptake is normal.
Small lymph nodes are seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
Multiple pure ground-glass nodules are seen in both lungs, with a long diameter of approximately 0.3-0.4 cm and indistinct borders; FDG uptake is normal.
Multiple solid nodules are seen in both lungs, some located in the subpleural region (including interlobar pleura); the largest is located in the posterior segment of the right lower lobe, with a long diameter of approximately 0.9 cm, clear borders, and slightly rough edges; FDG uptake is normal.
A few linear opacities are seen in both lungs.
No pleural thickening is observed bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Multiple lymph nodes are seen in the bilateral hilar and mediastinal regions; the largest has a short diameter of approximately 0.5 cm, and some show increased FDG uptake (SUVmax = 4.3).
The cardiac silhouette was normal, and myocardial FDG uptake was normal.
The esophageal wall showed no significant thickening or mass, and FDG uptake was not increased.
The right upper quadrant of the breast showed increased fibrous glands compared to the left, with punctate calcifications; FDG uptake was normal.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A cystic lesion approximately 0.6 cm in long diameter was seen at the top of the diaphragm in the right lobe of the liver; FDG uptake of the remaining liver parenchyma was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder's shape and size were normal, the gallbladder wall was not thickened, and no positive stones or significant masses were observed; FDG uptake was normal.
The pancreas's shape was normal, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
Spleen morphology and size normal, density and FDG uptake normal.
Accessory splenic nodules are seen around the spleen.
Both kidneys morphology and size normal, no obvious abnormal density shadows seen in the renal parenchyma, FDG uptake normal.
No widening of the renal pelvis, calyces and ureters bilaterally, no positive stones seen.
Both adrenal glands morphology and density normal, FDG uptake normal.
Poor gastric filling, no obvious abnormality in FDG uptake.
Poor bowel preparation, sigmoid colon wall thickened, the thickest part about 1.4cm, FDG uptake increased, SUVmax=7.2, affected length about 3.9cm, serosa slightly rough.
Multiple lymph nodes are seen in the retroperitoneal para-aortic region, mesenteric space, and bilateral anterior diaphragmatic groups, the largest about 0.6cm in short diameter, some with increased FDG uptake, SUVmax=1.6.
A large, irregular, multilocular cystic-solid lesion measuring approximately 16.5*14.6*23.0cm was observed in the abdominopelvic cavity.
The lesion had indistinct borders and poor demarcation from the surrounding intestines, bladder, and uterus.
The bilateral adnexa were not visualized.
The solid component showed increased FDG uptake (SUVmax = 2.3).
Multiple peritoneal thickenings were observed in the abdominopelvic cavity, some presenting as nodules or masses, with increased FDG uptake (SUVmax = 7.9).
A small amount of pelvic effusion was present.
No abnormal density shadows or abnormal FDG uptake were observed in the uterus.
The bladder was poorly filled, but no positive stones or obvious masses were observed.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation.
Patchy high-density shadows were observed at the margins of the L5 and S1 vertebral bodies.
L4/5 and L5/S1 intervertebral disc herniation with pneumothorax were observed.
FDG uptake of all bones was normal.

Impression

1. a. Thickening of the sigmoid colon wall with increased FDG metabolism, consistent with malignant tumor (lesion activity still present). Comparison with previous images and follow-up examination are recommended. b. Multilocular cystic-solid lesions in the abdominopelvic cavity with increased FDG metabolism in the solid component, suggestive of malignant tumor with activity; ovarian cancer is the primary consideration, metastatic tumor to be ruled out. Abdominal and pelvic peritoneal seeding metastasis with activity. Small amount of pelvic effusion. c. Retroperitoneal para-aortic, mesenteric, and bilateral anterior diaphragmatic lymph nodes show increased FDG metabolism in some areas, suggesting post-treatment changes from metastatic tumors or reactive lymph node hyperplasia. Comparison with previous images and follow-up examination are recommended. d. Liver cyst; no abnormal FDG metabolic foci seen in the liver parenchyma. Follow-up with enhanced MRI is recommended.

2. a. Multiple solid nodules in both lungs, FDG metabolism normal, suggest inflammatory nodules or post-treatment changes after metastatic tumor treatment. Comparison with old images and follow-up examination are recommended. b. Pure ground-glass nodules in both lungs, FDG metabolism normal, suggest chronic inflammatory nodules or atypical adenomatous hyperplasia. Annual HRCT follow-up is recommended. Bilateral pulmonary fibrosis. Reactive hyperplasia of hilar and mediastinal lymph nodes.

3. Increased fibrous glands in the upper outer quadrant of the right breast compared to the left, with punctate calcifications. FDG metabolism normal, suggest proliferative changes. Ultrasound follow-up is recommended to rule out other possibilities.

4. Uneven thyroid density, FDG metabolism normal. Ultrasound follow-up is recommended. Reactive hyperplasia of cervical lymph nodes.

5. Spinal osteophyte formation. L5 and S1 vertebral endplate inflammation. L4/5 and L5/S1 disc herniation with pneumoconiosis and degeneration.

6. Left temporal pole arachnoid cyst; FDG scintigraphy of the brain showed no obvious abnormalities.

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.
