The ventricular system was enlarged, with widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, 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.
The palatine tonsils showed physiological uptake.
The laryngopharynx morphology and structure were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and no abnormalities were observed in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region, and no abnormalities were observed in FDG metabolism.
A soft tissue mass was observed near the hilum of the left lower lobe, locally fused with enlarged hilar lymph nodes, with increased FDG metabolism.
The mass measures approximately 5.8 2.9 cm, with an SUVmax of 10.9.
There is bronchial occlusion in the basal segment of the left lower lobe, and patchy consolidation is visible around the mass.
A fluid-density shadow was seen in the left pleural cavity; a mixed ground-glass nodule measuring approximately 2.1 1.5 cm was observed in the anterior segment of the right upper lobe, with relatively clear borders and pleural retraction indentation, showing increased FDG metabolism (SUVmax = 2.8); multiple pure ground-glass nodules were observed in the apical-posterior segment of the left upper lobe, the anterior segment of the right upper lobe, and the anterior-basal segment of the right lower lobe, with relatively clear borders, the largest being located in the anterior segment of the right upper lobe, with a long diameter of approximately 0.5 cm, and FDG uptake was normal; multiple solid nodules were observed in both lungs, with relatively clear borders, the largest being approximately 0.3 cm in long diameter, and FDG metabolism was normal.
Multiple enlarged lymph nodes were observed in the left hilum, left superior mediastinum, paratracheal space, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, left internal mammary chain, and left anterior diaphragmatic group, the largest being approximately 2.1 cm in short diameter, with increased FDG metabolism (SUVmax = 11.5).
The cardiac silhouette was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
A small cystic lesion, approximately 0.3 cm in long diameter, was observed in the left inner lobe of the liver; FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormalities in localized FDG uptake.
The pancreas was normal in shape, with no significant 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.
The right kidney is normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is normal.
A small cystic lesion, approximately 0.3 cm in long diameter, is visible in the left kidney; FDG uptake is normal.
No obvious abnormalities are seen on the right adrenal gland.
The left adrenal gland is full in shape, with increased FDG metabolism (SUVmax = 2.8).
The stomach is poorly filled, with no obvious thickening of the stomach wall; FDG uptake is normal.
Focal increased FDG uptake is observed in the anal region (SUVmax = 7.9).
The prostate is of acceptable shape, with punctate dense shadows inside; FDG uptake is normal.
The bladder is generally full, with no obvious positive stones.
Multiple lymph nodes were observed in the hepatogastric space, portal vena cava, retroperitoneum, and bilateral inguinal regions, the largest with a short diameter of approximately 0.5 cm.
Some showed increased FDG metabolism, with an SUVmax of 1.9.
A small, round, dense shadow was visible subcutaneously in the left mid-abdomen; FDG showed no abnormalities.
A small amount of fluid-density shadow was observed within the bilateral testicular tunica vaginalis.
Scoliosis was present, with osteophyte formation at the margins of some vertebral bodies and L3/4 and L4/5 intervertebral disc bulging; FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. A mass near the hilum of the left lower lobe, with elevated FDG metabolism, consistent with central lung cancer with peripheral obstructive inflammation. Left pleural effusion. Multiple lymph node metastases in the left hilum and mediastinum. Possible metastases to the left internal mammary chain and left anterior diaphragmatic lymph nodes; follow-up is recommended.? b. A mixed ground-glass nodule in the anterior segment of the right upper lobe, with normal FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology.? c. Multiple pure ground-glass nodules in the apical-posterior segment of the left upper lobe, the anterior segment of the right upper lobe, and the anterior-basal segment of the lower lobe, with normal FDG metabolism; suggestive of atypical adenomatous hyperplasia or inflammatory nodules; annual HRCT follow-up is recommended.? d. Multiple chronic inflammatory micronodules (solid) in both lungs.? e. High probability of left adrenal hyperplasia; follow-up CT is recommended to rule out metastasis.

2. Focal increased FDG uptake in the anal area, highly suggestive of hemorrhoids; digital rectal examination is recommended to rule out tumors.

3. Small cyst in the left inner lobe of the liver. Small cyst in the left kidney. Subcutaneous calcification in the left mid-abdomen. Calcification in the prostate. Small amount of hydrocele in both testes.

4. Reactive hyperplasia of multiple lymph nodes in the hepatogastric space, portal vena cava, retroperitoneum, and bilateral inguinal regions.

5. Scoliosis with bone hyperplasia. L3/4 and L4/5 intervertebral disc bulge.

6. Age-related brain changes; contrast-enhanced MRI is recommended.

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.
