Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed:Reduced liver volume, widened hepatic fissures, and irregular margins.
Multiple round, uneven, slightly low-density lesions were observed in the left medial and lateral lobes of the liver and the upper and lower segments of the right anterior lobe, mostly located in the right lobe with indistinct borders.
The largest lesion in the right lobe measured approximately 5.3*9.7*10.8cm, with significantly increased FDG uptake (SUVmax=6.6).
Multiple enlarged lymph nodes were observed in the portal vena cava space and retroperitoneum.
The largest enlarged lymph node in the portal vena cava space fused into a mass, with a short diameter of approximately 3.0cm, showing significantly increased FDG uptake (SUVmax=8.0).
Multiple low-density bone destruction areas are visible on the right scapula, right 5th rib, T2 and its appendages, T10, left sacrum, ilium, and left ischium, with increased FDG uptake.
The largest lesion is on the left sacroiliac bone, measuring approximately 2.9*4.4cm, with an SUVmax of 8.8.
The portal vein is dilated, and multiple tortuous vessels are visible in the esophagus and gastric fundus.
The spleen is enlarged, with a superior-inferior diameter of approximately 17.9cm, and no significant abnormalities in FDG uptake.
Multiple nodular shadows are visible at the splenic hilum, the largest being approximately 1.9cm in diameter, with consistent FDG uptake throughout the spleen.
Abdominal and pelvic effusions are present.
The abdominal fat space and mesentery show increased density and are blurred, with slightly increased FDG uptake (SUVmax = 1.9).
The brain morphology and structure are normal, with a few punctate or patchy low-density lesions in the deep brain regions, and no abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns are slightly widened, but local density and FDG uptake are normal.
No significant dilation of the ventricular system is observed, and there is no midline shift.
The shape and outline of both eyeballs are normal, and the retrobulbar structures are clear; FDG uptake is normal.
The left maxillary sinus mucosa and left sphenoid sinus are slightly thickened, while the remaining paranasal sinus mucosa show no significant thickening, and the sinus walls are intact.
No significant thickening of the soft tissues on both sides of the nasopharynx is observed; the bilateral pharyngeal recesses are symmetrical, and FDG uptake is normal.
The oropharynx and bilateral palatine tonsils are full, and FDG uptake is physiological.
The laryngopharynx is normal in shape and structure, and the parapharyngeal space is clear.
The size, shape, and density of both parotid and submandibular glands are normal, and FDG uptake is physiological.
The thyroid gland is normal in shape and size; punctate slightly high-density shadows are visible in the right lobe of the thyroid gland, and FDG uptake is normal.
A small lymph node, approximately 0.5 cm in short diameter, is visible in the left infracervical space, with increased FDG uptake and an SUVmax of 3.5.
A mixed ground-glass nodule, approximately 0.9 x 1.4 cm in size, is visible in the posterior segment of the left upper lobe, with a maximum CT uptake of approximately -407 HU.
No significant abnormalities in FDG uptake were observed.
Multiple solid nodules and plaque-like lesions, approximately 0.3?.5 cm in long diameter, with clear borders, are visible in both lungs.
No significant abnormalities in FDG uptake were observed.
Diffusely distributed small cystic low-density shadows are visible in both lungs.
Lung markings are disordered and distorted.
A few patchy linear shadows, punctate lesions, plaque-like lesions, and calcifications are seen in both lungs, with no abnormalities in FDG uptake.
No significant pleural effusion is observed bilaterally.
A lymph node, approximately 0.8 x 1.0 cm in size, with high density and increased FDG uptake, is visible in the left hilum, with an SUVmax of 4.8.
Multiple calcifications are visible in the mediastinum and both lung hila.
Heart size is normal.
Aorta and its branches show calcification.
Bilateral breast development is present.
Esophageal dilatation is not observed, but the esophageal cardia is thickened; FDG uptake is normal.
Gastric distension is poor, with slight thickening of part of the gastric wall; FDG uptake is normal.
Intestinal distension is unsatisfactory; no local masses are observed; FDG uptake in part of the intestinal tract is physiological.
Gallbladder size and shape are normal; the gallbladder wall is slightly thickened; no positive stones or obvious masses are observed; FDG uptake in the gallbladder fossa is normal.
The peripancreatic space is relatively clear; no obvious abnormal density shadows are observed in the parenchyma; the pancreatic duct is not widened; FDG uptake is normal.
Bilateral adrenal glands show no abnormalities in shape, size, or density; local FDG uptake is normal.
Both kidneys are normal in shape and size.
A slightly high-density, round shadow, approximately 0.6 cm in diameter, is visible in the left renal cortex.
FDG uptake is not significantly abnormal.
No widening of the renal pelvis, calyces, or ureters is observed, and no positive stones are seen locally.
The bladder is poorly filled, but no positive stones are seen within the lumen.
The prostate is normal in shape and size, but punctate calcifications are seen within it.
FDG uptake is not focally elevated.
The spinal alignment is normal, with osteophyte formation at some vertebral margins and facet joints.
L3/4 and L4/5 intervertebral disc bulges, bilateral narrowing of the intervertebral foramina, and compression of the dural sac are observed.
L5/S1 intervertebral disc herniation is also present.

Impression

1. a. Multiple intrahepatic lesions with increased FDG metabolism, suggestive of hepatocellular carcinoma with multiple intrahepatic lesions; please correlate with clinicopathology. b. Multiple lymph node metastases in the portal vena cava space and retroperitoneum. Multiple bone metastases throughout the body. Left inferior deep cervical lymph node metastasis to be ruled out. c. Cirrhosis, splenomegaly, portal hypertension, esophageal and gastric varices. Accessory spleens (multiple). d. Abdominal and pelvic effusion. Increased density and blurred appearance of the abdominal fat space and mesentery, with slightly increased FDG uptake, suggestive of panniculitis; metastasis cannot be ruled out.

2. Mixed ground-glass nodules in the apical-posterior segment of the left upper lobe, with normal FDG uptake, highly suggestive of inflammatory lesions; CT scan recommended for comparison to rule out tumors. Multiple small chronic inflammatory nodules in both lungs; CT follow-up recommended. Chronic bronchitis in both lungs. Scattered post-inflammatory lesions in both lungs. Reactive hyperplasia of the left hilar lymph nodes. Calcification of the mediastinal and bilateral hilar lymph nodes. Sclerosis of the aorta and its branches. Bilateral breast development.

3. Slight thickening of the esophageal cardia and part of the gastric wall; FDG metabolism normal, suggestive of gastritis. Physiological uptake of part of the intestine. Chronic cholecystitis. Left renal cyst. Prostatic calcification.

4. Calcification in the right lobe of the thyroid gland; please combine with ultrasound examination.

5. Degenerative changes in the spine. L3/4 and L4/5 intervertebral disc bulge. L5/S1 intervertebral disc herniation.

6. Senile brain; a few lacunar ischemic lesions deep in the brain. Chronic inflammation of the left maxillary sinus and left sphenoid 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.
