A few linear shadows are seen in the right middle lobe.
The pleura is slightly thickened bilaterally; no significant pleural effusion is seen bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions; FDG uptake is not significantly increased.
The heart size is normal.
Increased fat density is observed in the anterior superior mediastinal region, with flocculent and punctate increased shadows; FDG uptake is normal.
Soft tissue nodules and masses are seen in the upper inner quadrant and lower outer quadrant of the right breast, and in the upper inner quadrant of the left breast (one nodule).
The borders are relatively clear.
A local fusion is observed in the lower outer quadrant of the right breast.
The largest axial section is approximately 3.5 2.6 cm.
No obvious calcification is seen.
FDG uptake is increased, SUVmax = 3.0.
An enlarged lymph node measuring approximately 0.8 1.1 cm is seen in the left axilla.
FDG uptake is increased, SUVmax = 6.0.
Small lymph nodes are also seen in the remaining two axillae.
Fat in the hilar region is visible, and FDG uptake is normal.
The esophagus is not dilated, and the wall is not significantly thickened or lumpy.
FDG uptake is normal.
The stomach is well-filled, with slight thickening of the antral wall.
FDG uptake is normal.
The intestines are not sufficiently full.
No masses are seen locally.
FDG uptake is increased in some intestinal segments, SUVmax = 3.1.
The liver has an irregular shape, with multiple low-density nodules and masses under the liver capsule.
Most have relatively clear borders, predominantly in the right lobe and partially fused.
The adjacent liver capsule is slightly concave.
Some lesions show patchy or linear low-density foci in the center, with varying degrees of increased FDG uptake (SUVmax = 7.1).
A few punctate and linear shadows are seen in the fat space adjacent to the right lobe of the liver and the right paracolic gutter, with no abnormal FDG uptake.
Small, flat lymph nodes are visible in the retroperitoneum, mesentery, and bilateral inguinal regions, the largest with a short diameter of approximately 0.6 cm, with no abnormal FDG uptake.
Abdominal and pelvic effusion is present.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and no abnormal FDG uptake in the gallbladder fossa.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen's shape and size are basically normal, and its density and FDG uptake are not abnormal.
The bilateral adrenal glands' shape, size, and density are normal, and local FDG uptake is not abnormal.
The bilateral kidneys' shape and size are normal, and no obvious abnormal density shadows are seen in the renal parenchyma; FDG uptake is not significantly abnormal.
No widening of the bilateral renal pelvis, calyces, or ureters is observed; the bladder is not distended, and no positive stones are seen locally.
The uterus's shape and size are normal, but FDG uptake in the uterine cavity is increased (SUVmax = 10.4).
Solid nodules are seen in the bilateral adnexa, with irregular shapes; the right nodule is larger, approximately 2.1 3.5 cm, and FDG uptake is increased (SUVmax = 2.7).
The spinal alignment is normal, and no obvious bone structural abnormalities are seen.
An L5/S1 intervertebral disc herniation is observed, but FDG uptake is not abnormal.
Increased FDG uptake was observed in strips within the muscle layer of the left upper wall, with SUVmax=5.4, and no obvious abnormalities were observed in local density.

Impression

1. a. Multiple space-occupying lesions in the liver with increased FDG metabolism. Combined with the enhanced MRI images from another hospital on June 7, 2023, malignancy is highly likely, possibly epithelioid hemangioendothelioma or sarcoma. A biopsy is recommended. b. A few punctate and linear shadows in the fat space adjacent to the right lobe of the liver and the right paracolic gutter, peritoneal seeding metastasis should be suspected. Follow-up CT scan is recommended. Abdominal and pelvic effusion. c. Solid nodules in the bilateral adnexa, irregular in shape, with slightly increased FDG metabolism. Neoplasticity needs to be ruled out. Further enhanced MRI is recommended. Physiological uptake in the uterine cavity is highly likely. d. Reactive hyperplasia of retroperitoneal, mesenteric, and bilateral inguinal lymph nodes. e. Scattered multiple solid nodules of varying sizes in both lungs, with smooth margins, are highly suggestive of metastatic tumors. Follow-up CT scan is recommended.

2. a. Multiple soft tissue lesions in both breasts, with slightly increased FDG metabolism. Based on the ultrasound report and MRI from another hospital, fibroadenoma is suspected. Please correlate with clinical findings and perform a biopsy if necessary to confirm the diagnosis. b. Reactive hyperplasia of bilateral axillary lymph nodes, including one enlarged lymph node in the left axilla with increased FDG metabolism. Please follow up with ultrasound to rule out metastasis.

3. A few fibrotic lesions in the right middle lobe of the lung. Incomplete thymic regression.

4. Gastric antrum in a contracted state, no increased FDG metabolism observed. Physiological uptake of some intestinal segments is highly likely.

5. A linear shadow with increased FDG metabolism in the muscle layer of the left upper wall, considered to be physiological or inflammatory uptake. Please correlate with clinical findings. L5/S1 disc herniation.

6. No obvious abnormalities were found on cranial scintigraphy.

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.
