Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure; punctate low-density shadows were visible in the deep bilateral cerebral regions, with no significant abnormalities in FDG uptake.
Some ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The density of the thyroid gland was unevenly decreased between the left and right lobes, with no abnormalities in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Increased lung markings were observed bilaterally.
A soft tissue mass measuring approximately 5.1*3.6*3.5cm was seen in the left upper lobe, with an average CT value of 42 HU.
The mass had relatively smooth margins, although the boundary with the pleura was indistinct in some areas.
A localized bronchial truncation was observed in the left upper lobe, with increased FDG uptake (SUVmax = 8.7).
Patchy and linear shadows were visible distal to and around the mass, but FDG uptake was not abnormal.
Several solid nodules were also observed in the apical-posterior segment of the left upper lobe, the dorsal segment of the left lower lobe, and the posterior segment of the right upper lobe.
The largest nodule was located in the apical-posterior segment of the left upper lobe, with a long diameter of approximately 0.9cm, and increased FDG uptake (SUVmax = 3.7).
The interlobular septa were thickened bilaterally, and scattered patchy and linear areas of increased density were visible in both lungs, with some areas showing slight FDG uptake (SUVmax = 1.2).
The pleura was thickened bilaterally, but there was no pleural effusion or pneumothorax.
Several enlarged lymph nodes were observed in the left hilar region, the largest being approximately 1.4 cm in short diameter, with increased FDG uptake (SUVmax = 7.9).
The cardiac silhouette was normal.
The esophagus showed no dilation, wall thickening, or mass, and FDG uptake was normal.
The bilateral breasts showed relatively dense fibrous tissue, without obvious masses or nodules, and FDG uptake was normal.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A cystic low-density lesion, approximately 2.0 cm in long diameter, with clear borders and absent FDG uptake, was observed on CT scan of the lower segment of the right anterior lobe of the liver.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, with no wall thickening and no abnormal local FDG uptake.
Following pancreatic lesion surgery, the pancreatic head showed an irregular shape, with a metallic dense shadow observed beside it.
FDG uptake was normal.
No significant abnormal density shadows were observed in the remaining pancreatic parenchyma, and the main pancreatic duct was not widened.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with thickening of the perirenal fascia in the left kidney.
A small nodular high-density shadow with a long diameter of approximately 0.8 cm was observed in the left renal parenchyma, with clear borders and no abnormal FDG uptake.
Spotted high-density shadows were observed in the left renal calyx.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was normal.
No significant abnormalities were observed on bilateral adrenal gland contrast imaging.
The stomach showed an irregular shape with suture shadows at the distal end.
FDG uptake was slightly increased in part of the anastomotic wall (SUVmax = 2.0).
The residual stomach was generally full, with visible chyme shadows.
No significant thickening of the gastric wall was observed, and FDG uptake was normal.
The intestines were poorly distended, with no obvious thickening or masses in the intestinal wall.
FDG uptake was increased in some intestinal segments, with an SUVmax of 11.0.
The uterus was normal in shape and size, with no abnormal density shadows and normal FDG uptake.
No obvious abnormalities were observed in the bilateral adnexa.
The bladder was well-distended, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Focal increases in FDG uptake were observed in the distal humerus bilaterally, the left humeral head, the right 4th rib near the axilla, the left ilium, the right acetabulum, the left femoral head, the S5 vertebral body, and the left sacral wing, with an SUVmax of 6.8.
Some areas showed slightly increased bone density unevenly, and some showed osteolytic bone destruction.
The spinal alignment was normal, with some vertebral bodies showing unevenly decreased bone density and some showing osteophyte formation at the vertebral margins.
Partial calcification was observed in the nuchal ligament.
L2/3, L3/4, and L4/5 intervertebral disc bulges, and L5/S1 intervertebral disc herniation are present, with no abnormalities in FDG uptake.
A fusiform low-density lesion with a long axis of approximately 1.6 cm and an average CT value of -93 HU is visible in the right external oblique muscle, with clear borders and absent FDG uptake.

Impression

1. a. Soft tissue mass in the left upper lobe of the lung with increased FDG metabolism, consistent with lung cancer based on pathology. b. Solid nodule in the posterior segment of the left upper lobe with increased FDG metabolism, suggestive of metastasis. c. Left hilar lymph node metastasis. Multiple bone metastases throughout the body (see description for details). d. Multiple small solid nodules in the remaining lungs, with no significant FDG uptake, highly suggestive of chronic inflammatory nodules; follow-up is recommended. Interstitial fibrosis in both lungs with scattered chronic inflammation and remnants. Bilateral pleural thickening. Bilateral incomplete breast regression; follow-up with ultrasound is recommended.

2. Postoperative changes in the pancreatic mass; no abnormalities were found in FDG metabolism at the surgical site; follow-up is recommended.

3. Highly suggestive of a liver cyst. Thickening of the left perirenal fascia, possible complex cyst in the left kidney; calcification of the left renal papillae; follow-up with ultrasound is recommended.

4. a. Post-gastric surgery changes: increased FDG metabolism in part of the anastomotic wall, possibly due to physiological uptake or chronic inflammation. Follow-up with clinical findings and gastroscopy is recommended. b. Increased FDG metabolism in part of the intestinal tract, possibly due to physiological uptake or chronic inflammation. Further colonoscopy is recommended to rule out other possibilities.

5. Osteoporosis. Spinal degeneration. L2/3, L3/4, L4/5 disc bulging, L5/S1 disc herniation. Right external oblique muscle lipoma.

6. Bilateral deep lacunar infarcts, age-related brain abnormalities. MRI is recommended.

7. Unevenly decreased density in the left and right lobes of the thyroid gland, with no abnormalities in FDG metabolism. Follow-up with ultrasound is 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.
