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; a round, high-density nodule approximately 1.4 cm in diameter with a CT value of approximately 45 HU was observed in the sellar region, indicating increased FDG metabolism (SUVmax = 3.5).
Mild widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious 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 bilaterally, and there was no stenosis of the Eustachian tube openings.
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 bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density, and no abnormal FDG uptake was observed.
Several enlarged lymph nodes were observed in the left occipital region, bilateral supraclavicular regions, and bilateral thoracic inlets, the largest measuring approximately 1.1 cm in short diameter, with increased FDG metabolism (SUVmax = 3.3).
A soft tissue nodule measuring approximately 1.1 cm in long diameter was observed subcutaneously in the left anterior chest wall, with increased FDG uptake (SUVmax = 1.8).
A lobulated soft tissue shadow measuring approximately 2.9 x 2.6 cm was observed in the lateral segment of the right middle lobe, with increased FDG metabolism (SUVmax = 5.8).
Several nodular shadows with clear borders were observed in the left lower lobe, the largest measuring 0.7 cm in long diameter, with slightly increased FDG metabolism (SUVmax = 1.8).
Multiple patchy, speckled, and linear shadows were observed in both lungs.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, para-aortic arch, main pulmonary window, and below the carina.
Some were fused into a mass, measuring approximately 7.7*5.4cm.
FDG metabolism was increased, with an SUVmax of 6.9.
Compression of the right main bronchus was observed.
Calcification of some arterial walls was present (including the coronary arteries).
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
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 or size, and the gallbladder wall showed no thickening; local FDG uptake was normal.
A soft tissue mass measuring approximately 5.7*4.9cm was observed in the pancreatic head region, with increased FDG metabolism and an SUVmax of 6.8.
The pancreatic body and tail are irregularly shaped, with increased FDG metabolism (SUVmax = 4.6), and no obvious dilation of the pancreatic duct is observed.
Multiple enlarged lymph nodes are present around the pancreas, in the right retrorenal space, part of the superior mesentery, and beside the bilateral iliac vessels; the largest has a short diameter of approximately 1.7 cm, with increased FDG metabolism (SUVmax = 6.5).
Multiple nodules are present in the peritoneum, the largest having a long diameter of approximately 2.1 cm; some show increased FDG uptake (SUVmax = 2.6).
The spleen's morphology, size, density, and FDG uptake are normal.
Both kidneys are normal in shape and size.
A cystic low-density lesion with a long diameter of approximately 1.2 cm is seen in the left kidney; FDG uptake is normal.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
A soft tissue nodule measuring approximately 1.4*1.3 cm is seen in the right adrenal gland, with increased FDG metabolism (SUVmax = 6.8).
The left adrenal gland shows no obvious abnormalities on contrast.
The stomach is poorly filled, with no obvious thickening of the stomach wall, and no significant abnormality in FDG uptake.
The intestines are poorly filled, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is of normal size and uniform density, and FDG uptake is not abnormally increased.
The bladder is generally full, with no obvious positive stones.
There is hydrocele in the right testis.
No obvious fluid accumulation is seen in the abdomen or pelvis.
Multiple bone destructions are observed in the right clavicle, right scapula, sacrum, right ilium, left acetabulum, and both femurs, with increased FDG metabolism (SUVmax = 5.7).
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.

Impression

1. a. A soft tissue mass with elevated FDG metabolism in the lateral segment of the right middle lobe of the lung, suggestive of malignancy, most likely small cell lung cancer, but metastasis cannot be ruled out; multiple lymph node metastases throughout the body (right hilum, mediastinum, left occipital region, bilateral supraclavicular regions, bilateral thoracic inlets, peripancreatic region, right retrorenal space, part of the superior mesenteric region, bilateral iliac vessels), some of which are fused. b. Right adrenal metastasis. Multiple bone metastases (see above for details). Peritoneal seeding metastasis. Subcutaneous metastatic nodules on the left anterior chest wall. c. Malignant tumor in the pancreatic head region, possibly originating from the pancreatic head, with enlarged and fused lymph nodes not ruled out; please combine with enhanced MRI for comprehensive analysis. Irregular shape of the pancreatic body and tail, elevated FDG metabolism, suggesting possible secondary inflammatory changes.

2. Several nodules in the left lower lobe of the lung with mildly elevated FDG metabolism, suggestive of chronic inflammatory nodules, metastasis to be ruled out; close CT observation is recommended. Chronic inflammation and remnants in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Left renal cyst. Right testicular hydrocele.

4. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge.

5. Sellar region mass, possibly pituitary tumor; age-related brain changes. Further 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.
