No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake was normal.
Scattered multiple solid nodules and masses were observed in the left pleura and left lung, predominantly in the pleura, with some areas coalescing into masses.
The internal density was heterogeneous, containing patchy low-density lesions and plaque-like high-density lesions, with absent FDG uptake.
The remaining solid portion showed increased FDG uptake (SUVmax = 17.2).
A left thoracic drainage tube was inserted, with blurred edges along its path on the chest wall, and increased FDG uptake (SUVmax = 5.4).
An irregular soft tissue nodule measuring approximately 1.2 1.0 cm was observed in the upper lobe of the right lung, with clear borders and increased FDG uptake (SUVmax = 2.8).
A few linear shadows and patchy calcifications were seen in the upper lobe of the right lung, and a few patchy and linear shadows were seen in the middle and lower lobes of the right lung; FDG uptake was not abnormal.
Multiple enlarged lymph nodes were observed in the posterior inferior mediastinum, beside the esophagus, beside the aortic arch, in the left internal mammary chain, and in both supraclavicular fossae.
The largest, approximately 1.9 1.3 cm, was located beside the aortic arch and showed increased FDG uptake (SUVmax = 13.0).
The heart size was not significantly abnormal.
No obvious soft tissue nodules or masses were seen within the fibroadenomas of both breasts; FDG uptake was not abnormal.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG uptake was not increased.
The stomach was poorly filled, and FDG uptake in the gastric wall was increased (SUVmax = 5.2).
Intestinal distension was unsatisfactory; no local masses were observed, and FDG uptake was normal.
The liver's shape and size were normal; the liver margins were smooth, and the hepatic fissures were not widened.
The liver parenchyma showed decreased density, with several roundish low-density lesions within it; the largest, located in the left lobe, was approximately 2.3 cm in diameter, with clear borders and absent FDG uptake.
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 obvious masses were observed; FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces were clear; no obvious abnormal density shadows were observed in the parenchyma; the pancreatic duct was not widened, and FDG uptake was normal.
The spleen's shape and size were essentially normal; density and FDG uptake were normal.
The left adrenal gland was enlarged; the right adrenal gland's shape, size, and density were normal, and local FDG uptake was normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the renal parenchyma, and no obvious abnormalities in FDG uptake.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally, 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 seen within the lumen.
Postoperatively after endometrial cancer surgery, no obvious abnormal soft tissue nodules or masses are seen in the surgical area, and FDG uptake is normal.
Enlarged and swollen lymph nodes are seen in the retroperitoneal space, beside the left aorta and in the hepatogastric space; the latter is larger, approximately 1.9 1.5 cm, with increased FDG uptake (SUVmax = 10.1).
An oval-shaped low-density lesion of approximately 2.0 2.5 cm is seen beside the right external iliac vessels, with clear borders and absent FDG uptake.
No obvious effusion is seen in the abdominal or pelvic cavities.
A nodular FDG uptake is observed in the right iliac spine, with an SUVmax of 7.9 and an uptake diameter of approximately 1.1 cm.
A low-density lesion with indistinct borders is seen in the muscle layer of the left forearm, with increased FDG uptake, an SUVmax of 5.4, and an uptake size of approximately 1.1 2.6 cm.
Scoliosis is present, with osteophyte formation at the margins of some vertebral bodies, and decreased FDG uptake in the lumbosacral spine.
Increased FDG uptake is observed in the soft tissues around both shoulder joints, with an SUVmax of 4.3.

Impression

1. a. Multiple lesions with internal necrosis and hemorrhage in the left pleura and left lung; soft tissue nodules in the right upper lobe; enlarged and swollen lymph nodes in the mediastinum, upper abdomen, and bilateral supraclavicular fossae; significantly increased FDG metabolism in the above lesions; focal FDG metabolism increase in the right iliac spine. All of the above lesions are considered malignant tumors, with the possibility of primary malignant tumors in the left lung or pleura with multiple metastases; metastatic tumors cannot be ruled out. A biopsy is recommended to confirm the diagnosis. b. Postoperative endometrial cancer surgery; no clear signs of tumor recurrence were observed in the surgical area.

2. Changes after placement of the left thoracic drainage tube. Old fibrosis and calcifications in the right upper lobe; a few chronic inflammations in the right middle and lower lobes.

3. Fatty liver; liver cysts; left adrenal hyperplasia; benign cystic lesions near the right external iliac vessels.

4. Poor gastric filling, with physiological uptake by the gastric wall.

5. Post-radiotherapy changes in the lumbosacral spine. Degenerative changes in the spine. Bilateral frozen shoulder.

6. No obvious abnormalities seen on cranial scintigraphy. Minor chronic inflammation of the bilateral maxillary sinuses. Calcifications on both sides of the oropharyngeal wall.

7. The left lobe of the thyroid gland is not clearly visualized; the right lobe shows decreased density with punctate calcifications and increased FDG metabolism. Please refer to the patient's history, ultrasound, and thyroid function tests.

8. Low-density lesions in the muscle layer of the left forearm with increased FDG metabolism, possibly due to drug contamination. Clinical correlation and follow-up are recommended.

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.
