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, with a few punctate or patchy low-density lesions in the deep brain regions; FDG uptake was normal.
Widening of some sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Normal morphology and contour of both eyeballs; clear retrobulbar structures; FDG uptake was normal.
No significant thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharynx; symmetrical pharyngeal recesses; increased FDG uptake (SUVmax = 4.1).
Normal morphology and structure of the oropharynx and laryngopharynx; clear parapharyngeal spaces.
Normal size, shape, and density of both parotid and submandibular glands; FDG uptake was physiological.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake is normal.
A patchy ground-glass opacity with a long diameter of approximately 1.5 cm was seen in the subpleural region of the right lung apex; the borders were indistinct; FDG uptake is normal.
A pure ground-glass nodule with a long diameter of approximately 0.4 cm was seen in the apical segment of the right upper lobe; the borders were relatively clear, with a maximum CT value of approximately -598 HU; FDG uptake is normal.
Multiple solid nodules were seen in the left upper lobe and right middle lobe; the largest was located in the inferior lingular segment of the left upper lobe, with a long diameter of approximately 0.4 cm; FDG uptake is normal.
Some bronchi in the apical segment of the right upper lobe were slightly dilated; a few linear opacities were seen in both lungs.
No significant pleural thickening was observed bilaterally; no significant pleural effusion was observed bilaterally.
Multiple small, flat lymph nodes were observed in the left hilum and mediastinum, with high density; the largest had a short diameter of approximately 0.7 cm and increased FDG uptake (SUVmax = 3.2).
The heart size was normal.
Calcification was observed in the walls of the aorta and its branches (including the coronary arteries).
No abnormal density shadows were observed within the fibroadenomas of both breasts, and FDG uptake was normal.
The esophagus was not dilated, and the wall was not significantly thickened or lumped; FDG uptake was normal.
The stomach was well-displaced, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 2.6).
Intestinal displacement was unsatisfactory; no local masses or significant focal FDG uptake were observed.
The liver morphology and size were normal, with smooth borders and no widening of the hepatic fissure.
Several cystic low-density lesions were observed within the liver parenchyma, with clear borders and absent FDG uptake; the largest had a long diameter of approximately 2.4 cm.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, the gallbladder wall was not thickened, and no positive stones or obvious masses were observed.
FDG uptake in the gallbladder fossa was normal.
The peripancreatic spaces were clear; the pancreatic head parenchyma was sparse and decreased in density, while the remaining parenchyma showed no obvious abnormal density shadows.
The pancreatic duct was not widened, and FDG uptake was normal.
The spleen was of essentially normal shape and size, and its density and FDG uptake were normal.
The left adrenal gland was enlarged, with increased FDG uptake (SUVmax = 2.8).
The right adrenal gland showed no abnormalities in shape, size, or density, and local FDG uptake was normal.
Both kidneys were of normal shape and size, with no obvious abnormal density shadows in the renal parenchyma and no obvious abnormal FDG uptake.
The renal pelvis, calyces, and ureters were not widened, and no positive stones were observed locally.
The bladder is poorly filled, and no positive stones were found in the cavity.
The uterus is normal in shape and size, with dense shadows and radiographic artifacts seen on both sides of the uterus; FDG uptake is normal.
No abnormal density shadows or increased FDG uptake were seen in the left adnexal region.
An oval cystic lesion measuring approximately 5.8 3.5 cm was seen on the right side of the pelvis (upper right side of the uterus).
The cyst wall was thickened and uneven, with punctate calcifications.
FDG uptake was partially absent in the cyst fluid, but increased in the cyst wall (SUVmax = 2.1).
The boundary between the lesion and adjacent intestinal segments was unclear.
Abdominal and pelvic effusion, partially encapsulated, with widespread and uneven thickening of the peritoneum, including the greater omentum, mesentery, perisplenic area, and bilateral paracolic gutter, predominantly in the greater omentum, showing increased FDG uptake (SUVmax = 2.2).
No enlarged lymph nodes were seen in the retroperitoneal region, and FDG uptake was not increased.
The spinal alignment is normal, with some vertebral body margin osteophytes, L3/4 disc bulge, and L4/5 disc herniation.
No abnormal FDG uptake was observed.
Increased FDG uptake was observed in both masseter muscles, with SUVmax = 6.3.

Impression

1. a. A cystic mass in the right pelvic cavity (upper right side of the uterus) with slightly increased FDG metabolism in the cyst wall, highly suggestive of an adnexal malignancy, such as ovarian cancer. Please combine tumor markers and enhanced MRI for comprehensive analysis. b. High probability of peritoneal seeding metastasis, tuberculosis to be ruled out. Please correlate with clinical findings. Abdominal and pelvic effusion, partially encapsulated.

2. a. High probability of subpleural inflammation in the right lung apex; possible chronic inflammatory ground-glass nodule in the apical segment of the right upper lobe, atypical adenomatous hyperplasia to be ruled out. HRCT follow-up is recommended for the above. b. Chronic inflammatory solid micronodules in the left upper lobe and right middle lobe, please follow up with CT. c. Slight bronchiectasis in the apical segment of the right upper lobe, a few fibrotic lesions in both lungs. Reactive hyperplasia of the left hilar and mediastinal lymph nodes. Partial arteriosclerosis (including coronary arteries).

3. Manifestations of chronic gastritis.

4. Liver cysts. Fatty infiltration of the pancreatic head. Left adrenal hyperplasia. Changes following bilateral fallopian tube ligation.

5. Degenerative changes in the spine. L3/4 disc bulge, L4/5 disc herniation. Bilateral physiological uptake of the masseter muscles.

6. Deep lacunar infarcts, age-related encephalopathy. Physiological uptake in the nasopharynx is highly probable; please correlate with clinical findings.

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.
