Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; FDG uptake was not significantly abnormal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical; and there was no midline shift.
No abnormalities were observed in the morphology and outline of the bilateral eyeballs; the retrobulbar structures were clear; the optic nerves were symmetrical; and FDG uptake was not abnormal.
Slight thickening of the mucosa of the bilateral maxillary sinuses, ethmoid sinuses, and sphenoid sinuses; a cystic, slightly low-density shadow was seen in the left maxillary sinus; FDG uptake was not abnormal; and the sinus walls were intact.
Slight thickening of the bilateral walls of the nasopharynx; increased FDG uptake (SUVmax = 9.7).
The bilateral palatine tonsils were symmetrical; FDG uptake was physiological.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
The bilateral parotid and submandibular glands had normal morphology and density; and FDG uptake was physiological.
The thyroid gland is normal in shape and size, with uniform density, and no abnormal FDG uptake was observed.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Increased translucency in both lung fields, with scattered cystic lucent shadows of varying sizes seen in the subpleural region; a soft tissue mass measuring approximately 4.8*3.8*3.4cm was observed in the left upper lobe adjacent to the mediastinum, with a mean CT value of 35 HU, relatively clear borders, but partially indistinct boundaries with the left subclavian artery and aortic arch, and increased FDG uptake (SUVmax=19.6).
Patchy and flocculent shadows were observed around the mass.
An irregular nodular lesion with a long diameter of approximately 1.1cm was observed in the apical segment of the right upper lobe, with slightly increased FDG uptake (SUVmax=2.5).
Several solid micronodules were observed in both lungs, with a long diameter of approximately 0.2-0.4cm, clear borders, and no abnormal FDG metabolism was observed.
A few calcifications and linear lesions were observed in both lungs, with no abnormalities in FDG metabolism.
No significant thickening of the pleura was observed bilaterally, and there was no pleural effusion or pneumothorax.
Multiple lymph nodes were visible in the left hilum and mediastinum (superior mediastinum, tracheovascular space, pretracheal vena cava, aortic window, para-aortic region, and subcarinal region), the largest being approximately 1.4 cm in short diameter, with increased FDG uptake (SUVmax = 5.0).
The cardiomegaly was present.
Calcification was observed in some arterial walls.
No dilation of the esophagus was observed, and no significant thickening or mass was seen in the esophagus; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A slightly low-density nodule with a long diameter of approximately 0.8 cm was observed in the upper segment of the right posterior lobe of the liver, with clear borders and decreased FDG uptake compared to background uptake.
Other roundish low-density shadows were observed in the upper segment of the right posterior lobe and the left lateral lobe, the largest being approximately 1.0 cm in long diameter, with clear borders and absent FDG uptake.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with a rough 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.
Both kidneys are normal in shape and size.
Roundish low-density shadows are seen in both kidneys, the larger one located in the right kidney, with a long diameter of approximately 1.5 cm and clear borders.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureters is observed bilaterally.
Adrenal gland imaging shows no obvious abnormalities, and FDG uptake is normal.
The stomach is adequately filled, with no obvious thickening of the stomach wall.
FDG uptake in the antral wall is slightly increased, SUVmax=3.2.
Intestinal filling is poor, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is slightly enlarged, with a transverse diameter of approximately 4.8 cm.
Calcifications are seen within the parenchyma, but FDG uptake is not abnormally increased.
The bladder is adequately filled, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes.
L4/5 and L5/S1 intervertebral disc herniation were observed, but FDG uptake was normal.
Subcutaneous calcifications were seen in the left buttock.

Impression

1. a. A mass in the left upper lobe of the lung, adjacent to the mediastinum, with increased FDG metabolism, consistent with lung cancer with surrounding inflammation. The boundary with the left subclavian artery and aortic arch is unclear. b. A lesion in the apical segment of the right upper lobe, with slightly increased FDG metabolism, suggesting a high probability of inflammatory changes. Regular CT follow-up is recommended to rule out metastasis. Chronic inflammatory lymph nodes in the left hilum and mediastinum are highly likely, with possible metastasis. Follow-up is advised. c. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. Emphysema and multiple bullae in both lungs. Enlarged cardiac silhouette, with partial calcification of arterial walls.

2. A slightly low-density nodule in the upper segment of the right posterior lobe of the liver, with decreased FDG metabolism, suggesting a small cyst or hemangioma. Comprehensive analysis with enhanced MRI is recommended. Liver cyst.

3. Rough gallbladder wall. Bilateral renal cysts. Benign prostatic hyperplasia with calcifications.

4. Mildly increased FDG metabolism in part of the gastric wall, considered physiological uptake or chronic inflammatory changes; please follow up with endoscopy.

5. Spinal degenerative changes. L4/5 and L5/S1 intervertebral disc herniation. Subcutaneous calcification in the left buttock.

6. Slight thickening of the bilateral nasopharyngeal walls with increased FDG metabolism, considered inflammatory changes.

7. No obvious abnormalities seen on cranial scintigraphy. Sinusitis with a submucosal cyst in the left maxillary sinus.

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.
