Post-treatment for right lung cancer: An irregular soft tissue mass measuring approximately 3.1*1.8*3.4cm was seen in the posterior segment of the right upper lobe, with clear borders, lobulated edges, and spiculation.
The adjacent pleura was stretched, and a local bronchus was truncated, containing an eccentric thick-walled cavity.
FDG uptake was unevenly increased, with SUVmax=12.1.
Patchy hazy shadows were seen distal to the lesion.
Multiple solid nodules were seen in both lungs, the largest being approximately 0.6cm in length in the right middle lobe, with clear borders and normal FDG uptake.
A pure ground-glass nodule approximately 0.7cm in length was seen in the posterior segment of the left lower lobe, with slightly indistinct borders and normal FDG uptake.
Scattered multiple cystic lucent shadows were observed in both lungs, along with a few linear shadows and patchy hazy shadows.
FDG uptake was normal.
Slight pleural thickening was present in some areas, but no significant pleural effusion was observed bilaterally.
Multiple lymph nodes were visible in the right hilum, below the carina, behind the trachea and vena cava, and in the aortic window, the largest with a short diameter of approximately 0.7 cm.
FDG uptake was increased, with an SUVmax of 4.1.
The heart was slightly enlarged.
Calcification was observed in the walls of the aorta and its branches (including the coronary arteries).
The right diaphragm was distended.
No esophageal dilatation or significant wall thickening or mass was observed.
FDG uptake was increased in the lower esophagus, with an SUVmax of 5.3.
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.
No dilatation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall.
Small patchy high-density lesions are seen within the gallbladder fossa, and FDG uptake in the gallbladder fossa is normal.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct is not widened, and FDG uptake is normal.
The spleen is basically normal in shape and size, with no abnormalities in density or FDG uptake.
The bilateral adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG uptake.
The kidneys are normal in shape and size, with a few patchy and linear shadows around the kidneys.
An oval low-density lesion with a long diameter of approximately 1.5 cm is seen in the parenchyma of the left kidney, with absent FDG uptake.
No obvious abnormal density shadows are seen in the parenchyma of the right kidney, and FDG uptake is normal.
No widening of the renal pelvis, calyces, or ureters is seen bilaterally, and no positive stones are seen locally.
Stomach distension is poor; the gastric angle and antrum walls are thickened with localized posterior depression; FDG uptake is increased (SUVmax = 5.5).
Several enlarged lymph nodes are seen in the hepatogastric space and on the lesser curvature of the stomach, the largest measuring approximately 1.7 0.9 cm; FDG uptake is normal.
No significant fluid accumulation is observed in the abdominal or pelvic cavities.
Intestinal distension is unsatisfactory; nodules are seen on the lower rectal wall; FDG uptake is increased (SUVmax = 6.0), with a long diameter of approximately 0.6 cm.
FDG uptake is increased in some intestinal segments (SUVmax = 7.6).
An air-filled cavity is seen in the descending duodenum; FDG uptake is normal.
The prostate is enlarged, with punctate calcifications; FDG uptake is uneven (SUVmax = 3.9).
Bladder distension is poor; no positive stones are seen within the cavity.
The spinal alignment is normal, with some vertebral body margin osteophytes, a fence-like appearance in the L1 vertebral body, L4/5 disc bulging, and some cervical, thoracic, and lumbar disc accumulation.
Increased FDG uptake around the right shoulder joint, SUVmax = 3.6.
A low-density fatty lesion measuring approximately 1.7 0.8 cm is seen within the left trapezius muscle; FDG uptake is normal.

Impression

1. Post-treatment PET/CT images of right lung cancer, compared with images from our center on February 7, 2023: a. A soft tissue mass in the posterior segment of the right upper lobe with increased FDG metabolism, significantly smaller than before, suggesting partial suppression of tumor activity after treatment, with some remaining; accompanied by minor distal obstructive changes. b. Right hilar and mediastinal lymph nodes, roughly the same size as before, with slightly decreased FDG metabolism; follow-up is recommended. c. Multiple small solid nodules in both lungs (some newly added), FDG metabolism normal, suggesting possible metastasis; regular CT follow-up is recommended. d. Ground-glass nodule in the posterior segment of the left lower lobe, FDG metabolism normal, roughly the same size as before; suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia; please combine with HRCT annual follow-up. Bilateral emphysema with bullae, bilateral pulmonary fibrosis.

2. Slight thickening of the pleura in some areas.

3. a. Thickening of the gastric angle and antrum walls with increased FDG metabolism, slightly relieved from before, suggesting possible inflammation; gastric cancer to be ruled out. Please combine with gastroscopy for comprehensive analysis. Lymph nodes in the hepatogastric space and lesser curvature of the stomach are roughly the same as before. b. Nodules in the lower rectal wall with increased FDG metabolism, suggesting possible inflammatory polyps or tubular adenomas. Colonoscopy follow-up is recommended to rule out other possibilities. c. Physiological or inflammatory uptake in the lower esophagus and part of the intestine. Duodenal diverticulum.

4. Benign prostatic hyperplasia with calcification, uneven FDG metabolism; please follow up with PSA and MRI. Gallstones. Thickening of the perirenal septum in both kidneys, left renal cyst.

5. Slightly enlarged heart. Partial arteriosclerosis (including coronary arteries).

6. Degenerative changes in the spine, L1 vertebral hemangioma, L4/5 intervertebral disc bulge, partial cervical, thoracic and lumbar intervertebral disc degeneration with pneumoconiosis. Right-sided frozen shoulder. Left trapezius muscle lipoma.

7. Bilateral deep lacunar infarcts, age-related cerebral encephalopathy. Minor chronic inflammation of the bilateral ethmoid sinuses and right 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.
