Normal morphology and structure of the laryngopharynx.
No abnormal visualization of bilateral salivary glands.
Normal morphology and size of the thyroid gland; slightly uneven density; FDG uptake was normal.
Several small lymph nodes, less than 0.4 cm in short diameter, were observed in the bilateral deep cervical spaces and submandibular region, with normal FDG uptake.
The thorax was symmetrical bilaterally, with thickening of the interlobular septa in both lungs, some showing a reticular pattern.
Multiple solid nodules and plaque-like lesions, approximately 0.3-0.4 cm in long diameter, were observed in both lungs, with normal FDG uptake.
Scattered linear and patchy opacities were observed in both lungs.
The trachea was midline, and the trachea and segmental bronchi were patent.
Multiple lymph nodes were observed bilaterally in the hilum, behind the vena cava, at the aortic window, and below the carina, the largest measuring approximately 0.8*0.5 cm at the aortic window.
FDG uptake was increased in some hilar lymph nodes bilaterally, with an SUVmax of 4.0.
Mild pleural thickening was observed bilaterally, with no pleural effusion or pneumothorax.
The cardiac silhouette was normal.
Following coronary stent placement, some arterial walls showed calcification (including the coronary arteries), and the ascending aorta was widened to approximately 4.5 cm.
The esophagus showed no dilation, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The bilateral mammary glands were relatively dense, with multiple punctate calcifications in both glands; FDG uptake was normal.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth, and the hepatic fissures were not widened.
Several cystic lesions were observed in the liver, the largest being approximately 0.9 cm in length in the caudate lobe; FDG uptake was normal.
A slightly low-density nodule with a long diameter of approximately 0.7 cm was observed in the left lateral lobe of the liver; the nodule had clear borders and FDG uptake was at background levels.
The main portal vein showed no significant widening, and the intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was rough, and a roughly round high-density lesion with a long diameter of approximately 4.1 cm was observed within it; FDG uptake was normal.
The pancreas showed no abnormalities in shape; a cystic lesion with a long diameter of approximately 1.4 cm was observed in the tail of the pancreas; the main pancreatic duct was not widened; FDG uptake was normal.
Spleen morphology and size were normal, as were density and FDG uptake.
Kidneys morphology and size were normal; a cystic lesion approximately 1.0 cm in long diameter was observed in the left kidney, with no significant abnormality in FDG uptake.
Neither renal pelvis, calyces, nor ureter was widened, and no positive stones were observed.
The left adrenal gland was enlarged, while the right adrenal gland morphology and density were normal, with no abnormal FDG uptake.
Stomach distension was poor, with a thickened antral wall and increased FDG uptake in parts of the gastric wall (SUVmax = 3.4).
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, but increased FDG uptake was observed in parts of the intestine (SUVmax = 5.4).
The uterus was shrunken, with no abnormal density shadows and no abnormal FDG uptake.
No abnormal density or FDG uptake was observed in the bilateral adnexa.
The bladder was adequately distended, with no positive stones or obvious masses observed.
Small lymph nodes were observed in the retroperitoneum, mesentery, and bilateral inguinal regions, with the largest having a short diameter less than 0.4 cm.
FDG uptake was normal.
No significant fluid accumulation was observed in the abdomen or pelvis.
Scoliosis was present, with osteophyte formation at the vertebral margins and flattening of the T11, T12, and L4 vertebrae.
Calcification of the nuchal ligament was observed, and thickening and calcification of the ligamentum flavum at the L4 and L5 levels were present.
L4/5 and L5/S1 intervertebral disc bulges were observed.
Following internal fixation of the right proximal femoral fracture, peripheral FDG uptake was increased, with an SUVmax of 3.7.
Cortical folds were observed in the right 7th, 8th, and 10th ribs and the left 10th rib, with callus formation in some mid-sections.
FDG uptake was increased, with an SUVmax of 2.8.
The mediastinal blood pool SUVmax was 2.9, and the hepatic blood pool SUVmax was 4.3, used for the Deauville score.

Impression

1. Post-lymphoma treatment: a. Thickened gastric antrum wall, with increased FDG metabolism in some gastric walls, suggesting post-treatment changes. Some tumor activity may still exist; please correlate with clinical findings and conduct follow-up examinations. b. Multiple lymph nodes are visible in the bilateral neck, hilum, mediastinum, retroperitoneum, mesentery, and bilateral groins. Increased FDG metabolism in the hilar lymph nodes suggests reactive lymph node hyperplasia or post-treatment changes; please compare with previous data and conduct follow-up examinations.

2. a. Interstitial lung changes with chronic inflammation and sequelae, chronic inflammatory nodules and plaque nodules in both lungs; please follow up with CT scans. Bilateral breast hyperplasia with calcification. b. Post-coronary artery stenting, partial arteriosclerosis (including coronary arteries), and ascending aortic dilation; please conduct specialist examinations.

3. Liver cysts, possible left lobe hemangioma; MRI examination if necessary. Gallstones, chronic cholecystitis. Left renal cyst. Left adrenal hyperplasia.

4. Cystic mass in the tail of the pancreas, FDG metabolism normal, cystadenoma to be ruled out, enhanced MRI recommended.

5. Increased FDG metabolism in some intestinal segments, considered physiological uptake or chronic inflammation, please follow up with endoscopy.

6. a. Scoliosis with degenerative changes. Old compression fractures of the T11, T12, and L4 vertebrae. L4/5 and L5/S1 intervertebral disc bulges. b. Post-internal fixation of the right upper femoral fracture, changes following fractures of the right 7th, 8th, and 10th ribs and the left 10th rib.

7. Bilateral deep lacunar infarcts, white matter degeneration, senile encephalopathy. Left maxillary sinusitis.

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.
