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, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; no midline shift was observed.
The eyes were symmetrical bilaterally, with no obvious abnormalities.
Thickening of the mucosa was observed in the left sphenoid sinus, bilateral ethmoid sinuses, and bilateral maxillary sinuses; a cystic shadow was seen in the left maxillary sinus.
The nasal septum was slightly deviated; no thickening of the nasopharyngeal wall was observed; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear; and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
The thyroid gland is normal in shape and size, but its density is somewhat heterogeneous; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular, patchy soft tissue density shadow is present in the right middle lobe of the lung, with indistinct borders and heterogeneous density, containing calcifications and low-density shadows, measuring approximately 8.4*8.3*7.6cm.
FDG uptake is unevenly increased, with SUVmax=16.8.
A bronchus in the right middle lobe is truncated, and the adjacent pleura is involved.
Multiple nodules and patchy lesions are present in both lungs, the largest being located subpleurally in the right lower lobe, measuring approximately 4.8*2.3cm.
FDG uptake is increased, with SUVmax=18.0.
Multiple bronchial wall thickenings are present in the upper and lower lobes of the right lung, and multiple bronchiectasis is present in both lungs.
Increased translucency in both lungs, with an air-filled cavity in the left upper lobe; scattered patchy and linear lesions in both lungs, with no abnormal FDG uptake.
Multiple pleural thickenings bilaterally with increased FDG uptake (SUVmax = 8.4), and bilateral pleural effusion (partially loculated).
Multiple enlarged lymph nodes were observed in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and right supraclavicular fossa, the largest with a short diameter of approximately 2.0 cm, showing increased FDG uptake (SUVmax = 12.1).
Cardiac enlargement, pericardial thickening with a small amount of effusion, and cardiac chamber density lower than myocardial density.
Calcification of some arterial walls (including coronary arteries) was observed.
The esophagus was not dilated, and no significant thickening or mass was observed in the esophagus wall; no increased FDG uptake was observed.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A small cystic lesion, approximately 0.4 cm in diameter, was observed at the top of the diaphragm, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, but the gallbladder wall was thickened, and a nodular dense shadow, approximately 0.6 cm in diameter, was observed within the gallbladder; local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys are normal in shape and size.
The left renal calyx shows punctate dense shadows, and several cystic lesions are present in the left renal parenchyma, the largest being approximately 2.2 cm in diameter.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
Stomach distension is poor, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake is slightly increased, SUVmax = 3.0.
Intestinal distension is unsatisfactory, with physiological uptake observed.
The prostate is normal in size, containing punctate dense shadows, and FDG uptake is not abnormally increased.
The left inguinal canal is widened, containing fatty components.
Calcification is present in the right testicular tunica vaginalis.
The bladder is poorly distended, with no obvious positive stones observed.
Multiple lymph nodes were observed in the right supradiaphragmatic and posterior diaphragmatic angle spaces, the largest measuring approximately 1.1 cm in short diameter, with increased FDG uptake (SUVmax = 6.1).
No significant fluid accumulation was observed in the abdomen or pelvis.
Multiple bone destruction was observed in the C7 vertebral body, T1, right transverse processes of T7, T6, T11 vertebral bodies, and left pubis, accompanied by increased FDG uptake (SUVmax = 7.4).
The spinal alignment was normal, with marginal osteophyte formation in some vertebral bodies, bilateral L4 spondylolysis with anterior vertebral body displacement, and multiple intervertebral disc bulges.

Impression

1. a. Irregular mass in the right middle lobe with increased FDG metabolism, suggestive of lung cancer with obstructive changes; multiple lymph node metastases in the bilateral hilar, mediastinal, right supraclavicular fossa, right supradiaphragmatic, and right posterior diaphragmatic angle spaces. b. Multiple metastatic tumors in both lungs; bilateral pleural metastases, bilateral pleural effusions (partially loculated). c. Multiple bone metastases throughout the body (see description for details).

2. Multiple bronchial wall thickenings in the upper and lower lobes of the right lung, multiple bronchiectasis in both lungs. Emphysema in both lungs, bullae in the left upper lobe. Chronic inflammation and post-inflammatory remnants in both lungs. Pericardial thickening with a small amount of effusion, anemia. Calcification of some arterial walls (including coronary arteries).

3. Small liver cysts. Chronic cholecystitis, gallstones.

4. Left renal cyst, left renal calculus. Prostatic calcifications. Left inguinal hernia. Right testicular tunica vaginalis calcifications.

5. Partial chronic inflammatory changes in the gastric wall.

6. Degenerative changes in the spine, bilateral L4 spondylolysis with anterior vertebral slippage, multiple intervertebral disc bulges.

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.
