Whole-body 18F-FDG PET/CT scan in a patient with Lymphoma taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
The ventricular system was enlarged, with widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx morphology and structure were normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
Thyroid gland density is uneven, with mild FDG uptake; SUVmax = 1.7.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
A small air-filled sac was visible next to the right trachea.
Multiple solid micronodules were seen in both lungs, with relatively clear borders; the largest was approximately 0.3 cm in long diameter.
Two punctate dense shadows were seen in the left lung.
Scattered linear and flocculent density shadows were seen in both lungs; FDG uptake was normal in all cases.
Pleural thickening was present bilaterally, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Pericardial thickening was slight.
A few glandular density shadows were seen in both breasts; FDG uptake was normal.
The liver margins are not smooth.
Multiple roundish low-density lesions of varying sizes are seen within the liver, the largest being approximately 13.4 9.2 cm in the right lobe, with increased FDG uptake (SUVmax = 48.0).
A small cystic lesion, approximately 0.5 cm in long diameter, is visible in the left medial lobe of the liver, with no abnormal FDG metabolism.
A small amount of fluid-density lesions are seen around the liver.
The main portal vein is not significantly widened, and no dilation is observed in the intrahepatic or extrahepatic bile ducts.
A small, round, dense lesion with slightly thickened walls is seen within the gallbladder lumen, with no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density lesions in the parenchyma.
The main pancreatic duct is not widened, and no obvious abnormal FDG uptake is observed.
The spleen's shape, size, density, and FDG uptake are normal.
A small splenic nodule is visible on the medial side of the spleen, with no abnormal FDG metabolism.
A cystic lesion with a long diameter of approximately 1.3 cm was observed in the right kidney, with no significant abnormality in FDG uptake.
The left kidney was normal in shape and size, with no significant abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
The lower thoracic esophagus wall was slightly thickened, with increased FDG uptake (SUVmax = 4.9).
The stomach was poorly filled, with no significant thickening of the stomach wall, and FDG uptake was not significantly abnormal.
An air-filled cavity was observed at the duodenal level, with no significant abnormality in FDG uptake.
FDG metabolism was increased in the anal region (SUVmax = 3.8).
The prostate was of acceptable size and homogeneous density, with increased FDG uptake in the bilateral peripheral zones (SUVmax = 2.4).
The bladder was generally full, with no obvious positive stones observed.
Multiple enlarged lymph nodes were observed in the hepatic hilum, intercaval space, hepatogastric space, perigastric region, right cardiophrenic angle, mesentery, retroperitoneum, and right pelvic wall.
The largest lymph node had a short diameter of approximately 1.8 cm.
FDG metabolism was increased, with an SUVmax of 37.5.
A small amount of fluid-density shadow was observed in the tunica vaginalis of both testes.
The spinal alignment was normal, with some vertebral body margin osteophytes, slight posterior displacement of the L3 vertebral body, slight anterior displacement of the L4 vertebral body, and L4/5 and L5/S1 intervertebral disc bulging.
FDG uptake was not abnormal.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. Multiple lesions in the liver with increased FDG metabolism suggestive of malignancy, most likely lymphoma, with metastases to be ruled out; small amount of perihepatic effusion. b. Multiple enlarged lymph nodes in the hepatic hilum, intercaval space, hepatogastric space, perigastric region, right cardiophrenic angle, mesentery, retroperitoneum, and right pelvic wall with increased FDG uptake suggestive of lymphoma infiltration, with metastases to be ruled out. A biopsy is recommended for the above to clarify the pathology.

2. Slight thickening of the lower thoracic esophageal wall with increased FDG metabolism suggests possible inflammation or lymphoma infiltration; endoscopy is recommended.

3. Increased FDG metabolism in the bilateral peripheral zone of the prostate suggests possible inflammation; tumor to be ruled out; PSA analysis is recommended.

4. a. Multiple chronic inflammatory micronodules in both lungs, calcification in the left lung, and a few post-inflammatory remnants in both lungs. b. Small diverticulum beside the right trachea. Bilateral pleural thickening. Slight pericardial thickening. Mild bilateral gynecomastia.

5. Small cyst in the left medial lobe of the liver. Gallstones and chronic cholecystitis. Accessory spleen. Right renal cyst. Small amount of hydrocele in both testes.

6. Diverticulum in the horizontal part of the duodenum. Focal increase in FDG uptake in the anal area, suggestive of hemorrhoids or physiological uptake; please correlate with clinical findings.

7. Uneven thyroid density, with mild FDG uptake in some areas, suggestive of nodular goiter; ultrasound and thyroid function tests are recommended.

8. Degenerative changes in the spine, with slight posterior slippage of the L3 vertebral body and slight anterior slippage of the L4 vertebral body. L4/5 and L5/S1 intervertebral disc bulges.

9. Age-related brain changes.

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.
