Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: A soft tissue nodule measuring approximately 1.0*0.6cm was observed in the sellar region, with increased FDG uptake (SUVmax = 15.5).
Patchy low-density shadows were seen in the deep cerebral regions bilaterally.
Some ventricles, sulci, fissures, and cisterns showed widening, but local density and FDG uptake were normal, and there was no midline shift.
The shape and outline of both eyeballs were normal, the retrobulbar structures were clear, the optic nerves were symmetrical, and FDG uptake was normal.
Mild thickening of the mucosa of the bilateral ethmoid sinuses and the left maxillary sinus was observed, with intact sinus walls.
No thickening of the nasopharyngeal wall was seen, and there was no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings.
The bilateral infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
Increased FDG uptake on the left oropharyngeal wall, SUVmax=7.5.
Physiological FDG uptake in the laryngopharynx.
No abnormal contrast enhancement seen in bilateral parotid and submandibular glands.
Thyroid gland morphology and size normal; a slightly low-density nodule measuring approximately 1.6*1.2cm is seen in the right lobe, with partially indistinct borders; FDG uptake is normal.
Small lymph nodes are seen in bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
Post-treatment for right lung cancer: An irregular soft tissue density lesion measuring approximately 4.4*2.9cm is seen near the hilum of the right upper lobe, with clear borders, lobulated edges, and spiculation; pleural traction is present, with local bronchial transection; FDG uptake is increased, SUVmax=24.3; a few punctate and nodular lesions are seen distal to the lesion.
Multiple solid micronodules were observed in both lungs, along with a few linear opacities and air-containing radiolucent shadows.
A patchy shadow was seen paravertebrally in the right lower lobe.
FDG uptake was normal.
Slight pleural thickening was observed bilaterally, but there was no pleural effusion or pneumothorax.
Several lymph nodes were observed in the right hilum, pretracheal space, aortic window, and subcarinal region, the largest with a short diameter of approximately 1.1 cm.
Some showed increased FDG uptake, with an SUVmax of 4.6.
The cardiac silhouette was full, with pericardial effusion.
Myocardial FDG uptake was normal.
No significant thickening or mass was observed in the esophageal wall, and FDG uptake was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
No significant abnormal density shadows were observed in the liver parenchyma, and FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder appears normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake.
The pancreas appears normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen appears normal in shape and size, with no abnormal density or FDG uptake.
The right kidney is absent postoperatively, with no abnormal density shadows in the surgical area and no abnormal FDG uptake.
The left kidney is full, with no obvious abnormal density shadows in the renal parenchyma and no abnormal FDG uptake.
The left renal pelvis, calyces, and ureter are not widened, and no positive stones are found.
A slightly low-density nodule with a long diameter of approximately 1.5 cm is seen in the left adrenal gland, with increased FDG uptake (SUVmax = 3.8).
Stomach distension is poor, with increased FDG uptake in some gastric walls (SUVmax = 2.6).
Bowel preparation is poor; nodular protrusions are visible on the mid-abdomen small intestine wall, with increased FDG uptake (SUVmax = 3.0); increased FDG uptake in the remaining intestinal segments (SUVmax = 5.2).
Prostate morphology and size are normal; no obvious abnormal density shadows are seen in the parenchyma; FDG uptake is normal.
Bladder distension is poor; no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
Small lymph nodes are seen in both inguinal regions; FDG uptake is normal.
No obvious fluid accumulation is seen in the abdomen or pelvis.
Spinal alignment is normal; some vertebral body margins show osteophyte formation; L2/3 and L3/4 intervertebral discs are slightly bulging; L4/5 intervertebral disc posterior margin is calcified.
FDG uptake in all bones is normal.
Two slightly low-density nodules were observed on the medial side of the left scapula, with indistinct borders.
The larger nodule measured approximately 2.3*1.3cm.
No abnormalities were found in FDG uptake.

Impression

1. Post-treatment of right lung cancer: a. Soft tissue mass near the hilum of the right upper lobe with increased FDG metabolism, suggesting residual tumor activity, accompanied by minor distal obstructive changes. b. Metastasis to the right hilar and part of the mediastinal lymph nodes. c. Left adrenal metastasis is the primary consideration; follow-up is recommended to rule out other possibilities.

2. Sellar region mass, metastatic tumor to be ruled out; enhanced pituitary MRI is recommended for further examination. Lacunar infarcts in both lobes, senile encephalopathy.

3. Chronic inflammatory micronodules in both lungs, chronic inflammation and sequelae in both lungs, emphysema. Slight pleural thickening bilaterally. Pericardial effusion.

4. Right kidney absent post-surgery; no signs of tumor recurrence were observed in the surgical area.

5. Increased FDG metabolism in parts of the stomach wall and intestines, suggesting physiological uptake or chronic inflammation. Suspicious nodular protrusions in the mid-abdomen small intestine wall; please follow up with endoscopy. Reactive hyperplasia of bilateral inguinal lymph nodes.

6. Spinal degenerative changes. Slight bulging of L2/3 and L3/4 intervertebral discs; calcification at the posterior margin of L4/5 intervertebral disc. Slightly low-density nodule on the medial side of the left scapula, likely benign; enhanced MRI is recommended.

7. Physiological or inflammatory changes on the left side of the oropharyngeal wall; ENT examination is recommended to rule out other possibilities. Chronic inflammation of bilateral ethmoid sinuses and the left maxillary sinus.

8. Slightly low-density nodule in the right lobe of the thyroid gland; FDG metabolism is normal, suggesting nodular goiter; ultrasound follow-up is recommended. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
