Extensive irregular thickening of the gastric wall with increased FDG uptake, SUVmax=7.8, the thickest part approximately 3.2cm; thickening of the small intestine wall in the midline of the pelvis with increased FDG uptake, SUVmax=6.2.
No obvious abnormalities in liver morphology and size; smooth liver margins; no widening of the liver fissure; multiple low-density lesions under the liver capsule, the largest approximately 2.4cm in diameter, with increased FDG uptake, SUVmax=5.3.
Several slightly low-density nodules seen in the liver parenchyma, the largest approximately 2.6*1.9cm, with FDG background uptake.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder appeared normal in shape and size, with a dense nodule within, approximately 2.1 cm in long diameter.
The gallbladder wall showed no thickening, and local FDG uptake was normal.
The pancreas appeared 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 was enlarged, with increased FDG uptake (SUVmax = 5.0).
Both kidneys appeared normal in shape and size.
A slightly high-density nodule was observed in the left renal parenchyma, approximately 0.7 cm in diameter.
FDG metabolism was normal.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
No obvious abnormalities were observed on the left adrenal gland.
A low-density mass, approximately 4.1 x 2.5 cm in size, was observed in the right adrenal region, with increased FDG uptake (SUVmax = 5.8).
Post-hysterectomy, uterus absent.
No obvious abnormalities seen in bilateral adnexa.
Poor bladder filling, with an inserted urinary catheter.
Small amount of pelvic effusion.
Multiple nodular and patchy soft tissue density shadows in subcutaneous soft tissue and muscles throughout the body, the most prominent being in the right buttock, measuring approximately 4.6*2.5cm, with increased FDG uptake, SUVmax=7.0.
Unevenly increased FDG uptake in the medullary cavity throughout the body, SUVmax=4.7.
Spinal alignment normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
Subcutaneous edema in the abdomen and buttocks.
Mediastinal blood pool SUVmax=1.7, liver SUVmax=2.7, used for Deauville score.

Impression

1. a. Multiple lymphadenopathy throughout the body with increased FDG metabolism (see description for details); multiple nodular soft tissue density shadows in the abdominopelvic cavity with increased FDG metabolism; b. Extensive and irregular thickening of the gastric wall with increased FDG metabolism; thickening of the small intestine wall in the midline of the pelvis with increased FDG metabolism; c. Multiple low-density lesions under the liver capsule with increased FDG metabolism; splenomegaly with increased FDG metabolism; space-occupying lesion in the right adrenal region with increased FDG metabolism; d. Multiple nodular and patchy soft tissue density shadows in the subcutaneous soft tissue and muscles throughout the body with increased FDG metabolism; heterogeneous increased FDG metabolism in the bone marrow cavity throughout the body. Based on the medical history, all of the above suggest multisystemic lymphoma infiltration. Follow-up after treatment is recommended.

2. Uneven density in the left and right lobes of the thyroid gland; low-density nodule with calcification in the left lobe; increased FDG metabolism; thyroid cancer to be ruled out; further ultrasound examination recommended.

3. Chronic inflammatory lesions in the upper lobes of both lungs. Scattered fibrotic lesions in both lungs. Bilateral pleural effusion; partial atelectasis in the lower lobes of both lungs. Anemia changes; partial calcification of arterial walls (including coronary arteries). PICC line inserted.

4. Calcification in the right breast.

5. Possible intrahepatic hemangioma; comprehensive analysis with contrast-enhanced MRI recommended. Cholelithiasis. Complex cyst in the left kidney. Urinary catheter inserted. Post-hysterectomy changes. Small amount of pelvic effusion.

6. Degenerative changes in the spine; L4/5 and L5/S1 intervertebral disc bulge. Subcutaneous edema in the abdomen and buttocks.

7. Cranial scintigraphy showed no obvious abnormalities. Chronic sphenoid sinusitis. Osteoma of the right frontal bone. Benign bone lesion of the right parietal bone.

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.
