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 punctate low-density shadows visible in the deep bilateral cerebral regions; FDG uptake was not significantly abnormal.
The ventricular system was slightly enlarged, with widening of the sulci, fissures, and cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
The right maxillary sinus mucosa was slightly thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, 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 bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx morphology and structure were normal.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and no abnormalities were observed in FDG uptake.
Multiple enlarged lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, the largest with a short diameter of approximately 1.0 cm.
Some of these lymph nodes showed increased FDG metabolism, with an SUVmax of 6.9.
A soft tissue mass was observed in the left upper lobe near the hilum, with indistinct borders and irregular edges.
It measured approximately 6.0 3.8 cm and had heterogeneous internal density.
The lesion was mostly located in the apical-posterior segment and lingular segment of the upper lobe.
The bronchus in the lower lingular segment of the upper lobe was involved and truncated.
The boundary between the lesion and the adjacent interlobar pleura and hilar tissue was unclear.
FDG uptake was increased, with an SUVmax of 24.4.
Patchy shadows were visible around the lesion.
Multiple small nodules were observed in both lungs, the largest being approximately 0.3 cm in length.
Multiple small, round, high-density shadows were also seen in the right lung; FDG metabolism was normal.
Scattered linear and flocculent density shadows were observed in both lungs, mostly located subpleurally; FDG metabolism was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Multiple enlarged lymph nodes were observed in the left hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest being approximately 0.9 cm in short diameter; FDG metabolism was increased, with SUVmax = 6.1.
Calcification was observed in the walls of the aorta and coronary arteries.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The liver's shape and size were normal; the liver margins were smooth, and the hepatic fissure was not widened.
A small cystic lesion, approximately 0.5 cm in length, was seen in the left medial lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Small splenic nodules were observed around the spleen, but FDG metabolism was normal.
A small cystic shadow was seen in each kidney, the right one being larger and denser, with a long diameter of approximately 0.6 cm; FDG uptake was normal.
Bilateral adrenal gland contrast was normal.
The stomach was poorly distended, with thickening of the gastric fundus and body mucosa and increased FDG uptake (SUVmax = 6.1).
Strip-shaped FDG uptake was observed in the terminal ileum (SUVmax = 7.7).
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder is generally full, and no obvious positive stones are seen.
Multiple nodular shadows are seen in the abdomen (paragastric antrum, mesenteric, retroperitoneal, and presacral), with smooth margins.
The largest is located paragastric antrum, measuring approximately 1.4 1.8 cm.
Some nodules show increased FDG metabolism, with SUVmax = 6.7.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes, calcification of the nuchal ligament, and L3/4 and L4/5 intervertebral disc bulging.
FDG uptake is normal.
The T9 vertebral body shows a palisade-like appearance with decreased FDG uptake.
Nodular decreased density shadows are seen at the anterolateral margin of the right femoral head, with no abnormal FDG uptake.
Focal increased FDG uptake is seen at the lateral margin of the left acetabulum, with SUVmax = 5.8.

Impression

1. a. A mass near the hilum in the left upper lobe of the lung, with increased FDG metabolism, suggestive of lung cancer with surrounding obstructive inflammation; please correlate with clinicopathology. Multiple lymph node metastases in the left hilum and part of the mediastinum are possible. b. Multiple chronic inflammatory nodules in both lungs; follow-up CT is recommended. Multiple calcifications in the right lung, interstitial inflammation in both lungs. Slight thickening of the pleura bilaterally. Partial calcification of the aorta and coronary artery walls.

2. Multiple soft tissue nodules in the abdomen (paragastric antrum, intermesenteric, retroperitoneal, and presacral), with increased FDG metabolism in some areas, suggestive of lymphoproliferative disorders; regular follow-up CT is recommended, and clinicopathology should be considered if necessary.

3. Small cyst in the left medial lobe of the liver. Accessory spleen. Small cysts in both kidneys (complex cyst on the right).

4. Thickening of the gastric fundus and body mucosa with increased FDG uptake, suggestive of inflammation. Strip-shaped FDG uptake in the terminal ileum suggests inflammation or physiological uptake. Endoscopic follow-up is recommended.

5. Spinal degenerative changes. L3/4, L4/5 intervertebral disc bulge. Possible T9 vertebral hemangioma. Right femoral head hernia fossa. Focal increased FDG uptake at the left acetabular rim, suggestive of inflammation.

6. Bilateral deep lacunar infarcts. Age-related brain changes. Reactive hyperplasia of multiple lymph nodes in the bilateral deep cervical spaces and submandibular region.

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.
