Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed 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.
Both palatine tonsils showed physiological uptake.
The morphology and structure of the laryngopharynx were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland showed full volume and uneven density in both lobes and isthmus, with calcification in the right lobe.
FDG metabolism was increased, with SUVmax = 2.6.
An irregular, patchy mass measuring approximately 10.5 6.8 7.5 cm was observed in the lower lobe of the left lung, with elevated FDG metabolism (SUVmax = 18.5).
Thickening of the adjacent left posterior pleura was also observed.
Several small solid nodules, approximately 0.3 cm in long diameter, were seen in the left interlobar pleura, with normal FDG uptake.
A small ground-glass opacity nodule, approximately -596 HU on CT, with a long diameter of approximately 0.4 cm and relatively clear borders, was seen in the posterior segment of the left upper lobe, with normal FDG metabolism.
Multiple small solid nodules, approximately 0.2-0.3 cm in long diameter, with clear borders, were seen in both lungs, with normal FDG metabolism.
A few linear opacities were seen in both lungs.
There was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the bilateral pulmonary hila, superior mediastinal vascular space, pretracheal space, para-aortic arch, aortic window, subcarinal region, right paraesophageal region, and bilateral supraclavicular fossa.
The largest lymph node had a short diameter of approximately 1.3 cm, with increased FDG metabolism (SUVmax = 14.2).
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
Bilateral mammary glands showed dense fibrous tissue, and FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no obvious abnormal density shadows in the liver parenchyma on plain CT scan; 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 was normal in shape and size, with no thickening of the gallbladder wall; 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; FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
A soft tissue nodule measuring approximately 2.0 1.6 cm was observed in the right adrenal gland, with clear borders and background FDG uptake.
The left adrenal gland showed no obvious abnormalities on contrast imaging.
Gastric distension was poor, with slight thickening of the walls of part of the gastric body and antrum, and mildly increased FDG uptake (SUVmax = 2.3).
Intestinal distension was unsatisfactory, with increased FDG metabolism in parts of the intestine (SUVmax = 4.5).
The uterus had an irregular outline, with an irregular nodule measuring approximately 1.8 2.0 cm on the left anterior wall; FDG metabolism was normal.
Cystic lesions were observed in both adnexa, the larger one on the right measuring approximately 6.3 5.4 cm, with slight FDG uptake at the periphery.
The bladder was adequately distended, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Bone destruction was observed in the right scapula, left 5th rib, left 8th rib, right 3rd rib, multiple vertebral bodies and appendages of the spine, sacrum, left ischium, and right iliac bone.
FDG metabolism was elevated, with SUVmax = 5.9.
The spinal alignment was normal, with minor osteophyte formation at the margins of some vertebral bodies.
L4/5 intervertebral disc bulge with pneumothorax and L5/S1 intervertebral disc herniation were observed.

Impression

1. a. A mass in the lower lobe of the left lung with increased FDG metabolism, suggestive of lung cancer, with a high probability of invasion of adjacent pleura and interlobar pleural metastasis. Pathological examination is recommended. Multiple lymph node metastases in the bilateral hilar, mediastinal, and bilateral supraclavicular fossae. Multiple bone metastases throughout the body. b. A ground-glass nodule in the apical-posterior segment of the left upper lobe, with normal FDG metabolism, suggestive of an inflammatory nodule or atypical adenomatous hyperplasia. Annual HRCT follow-up is recommended. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. c. A soft tissue nodule in the right adrenal gland with basal FDG uptake, suggestive of adenoma, metastasis to be ruled out. Follow-up CT examination is recommended.

2. Bilateral breast proliferative changes.

3. Thyroid gland with uneven density and increased FDG metabolism, suggestive of chronic inflammation. Ultrasound and laboratory tests are recommended. Calcification in the right lobe of the thyroid gland.

4. Slight thickening of the gastric body and antrum walls, with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG metabolism in some intestinal segments, suggestive of inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended.

5. Uterine fibroids. Cystic lesions in both adnexa, most likely ovarian cysts; the right lesion is a cystadenoma or other possibilities to be ruled out. Please combine clinical findings with MRI examination.

6. Mild osteophyte formation in the cervical, thoracic, and lumbar spine. L4/5 disc bulge with pneumothorax and degeneration; L5/S1 disc herniation.

7. No abnormalities seen on cranial scintigraphy; please follow up with MRI. A small amount of chronic inflammation in the 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.
