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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: Following comprehensive treatment for lymphoma: Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, the largest with a short diameter of approximately 0.5 cm; no significant increase in FDG uptake was observed.
A few soft tissue shadows were seen in the left posteroinferior mediastinum (post-medial to the descending aorta at the T8 level), with mild FDG uptake (SUVmax = 3.5).
No enlarged lymph nodes were seen in the mediastinum or bilateral hila.
Postoperatively for gastric lymphoma in the lesser curvature, the gastric wall in the surgical area was slightly thickened with mild FDG uptake (SUVmax = 3.3).
A lymph node was seen in the right inguinal region, with a short diameter of approximately 0.7 cm; FDG uptake was not high.
Small lymph nodes were seen in the hepatogastric space, hepatic hilum, and right pelvic wall; the largest, located on the right pelvic wall, measured approximately 1.0*0.3 cm; no significant increase in FDG uptake was observed.
The brain morphology and structure are normal.
Fat density nodules and calcifications are present in the quadrigeminal cisterns; the long axis of the fat density nodules is approximately 0.6 cm, and FDG uptake is normal.
No widening of the ventricles, sulci, fissures, or cisterns is observed; local density and FDG uptake are normal, and midline structure shift is not observed.
The bilateral eyeballs have normal morphology and outline, and FDG uptake is normal.
Mild thickening of the right maxillary sinus mucosa is observed, but the sinus wall is intact.
No thickening of the nasopharyngeal wall is observed; FDG uptake is normal.
The pharyngeal recesses are symmetrical, and FDG uptake is normal.
Both palatine tonsils are full and well-formed.
The laryngopharynx has normal morphology and structure, and the parapharyngeal space is clear.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
The bilateral thoracic walls are symmetrical.
Multiple thin-walled cystic lesions are observed in both lungs.
Multiple patchy and strip-like shadows are seen in both lungs, with increased FDG uptake (SUVmax = 1.8), and some adjacent pleural thickening and adhesions.
Multiple irregular calcifications were observed in both lungs, the largest being approximately 1.4 cm in length in the right middle lobe.
Scattered linear lesions were also seen in both lungs.
The heart was within the normal size range.
A small amount of fluid was observed in the pericardial recesses and at their bases.
Partial arteriosclerosis was present.
Both breasts showed dense glandular tissue with no abnormal density shadows, and no abnormal uptake was observed on FDG.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Multiple solid lesions were observed within the liver, the largest being approximately 2.0*3.5 cm in size, located at the junction of the left and right lobes, and showed background uptake on FDG.
The main portal vein showed no obvious widening.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no obvious abnormalities, with a clear gallbladder fossa space, and no abnormal uptake on FDG.
The pancreas had a clear outline, normal shape and size, with no obvious abnormal density shadows, no widening of the pancreatic duct, and no abnormal uptake on FDG.
The spleen showed no abnormalities in shape, density, or FDG uptake.
Both kidneys are normal in shape and size, with no abnormal density shadows seen in the renal parenchyma, and no significant abnormalities in FDG uptake.
No widening of the renal pelvis, calyces, or ureters is observed, and no positive stones are seen.
The right adrenal gland is normal in shape and density.
A small nodule, approximately 1.0 cm in diameter, is seen in the left adrenal region, with no abnormal FDG uptake.
The esophagus is not dilated, and no increased FDG uptake is observed in the local esophageal wall.
Intestinal distension is unsatisfactory, with no local masses, but increased FDG uptake in some intestinal segments (SUVmax = 4.1).
A cystic shadow is seen in the descending duodenum.
Increased FDG uptake in the anal canal (SUVmax = 6.8).
Post-hysterectomy.
The bladder is adequately distended, with no positive stones or significant masses seen locally.
Scoliosis is present, with sacralization of the L5 vertebra.
Osteophyte formation is seen at the margins of some vertebral bodies.
Mild bulging of the L2/3 intervertebral disc is present.
FDG metabolism is decreased in some thoracic vertebrae.
The mediastinal blood pool SUVmax was 2.4, and the liver SUVmax was 2.8, used for the Deauville score.

Impression

1. Following comprehensive treatment for lymphoma, comparing PET/CT images from our center on December 25, 2021: a. Postoperative gastric lesser curvature lymphoma surgery showed slight thickening of the gastric wall in the surgical area with mild FDG uptake, suggesting postoperative changes; the soft tissue nodules in the left posteroinferior mediastinum (medial to the descending aorta at T8 level) decreased in size, with reduced FDG metabolism; the right inguinal lymph nodes also decreased in size, with reduced FDG metabolism. These findings suggest effective lymphoma treatment. b. Multiple small lymph nodes throughout the body (see description for details) showed no significant increase in FDG metabolism, remaining similar to previous findings, suggesting suppressed lesion activity or possibly reactive proliferative lymph nodes after treatment. c. Patchy and strip-like lesions in both lungs with increased FDG metabolism, some adjacent pleural thickening and adhesions, and some newly added lesions suggest a high probability of inflammatory lesions. Please follow up with CT scans to rule out other possibilities.

2. Multiple thin-walled cystic lesions in both lungs, scattered post-inflammatory remnants (including calcifications) in both lungs, roughly similar to previous findings. A small amount of effusion in the pericardial recesses and at their bases. Partial arteriosclerosis. Bilateral breast hyperplasia.

3. Multiple solid lesions in the liver, roughly similar to previous findings, suggestive of hemangioma; enhanced MRI follow-up is recommended. A small nodule in the left adrenal region, roughly similar to previous findings, highly suggestive of adenoma.

4. Chronic inflammatory changes or physiological uptake in some intestinal segments; endoscopic follow-up is recommended. Duodenal diverticulum. Hemorrhoidal changes.

5. Scoliosis with degenerative changes. Post-radiotherapy changes in some thoracic spine segments. Mild L2/3 intervertebral disc bulge.

6. Lipoma and calcifications in the quadrigeminal cistern. A small amount of inflammation in the right maxillary sinus.

7. Thyroid gland density is uneven; FDG metabolism is normal; ultrasound follow-up is recommended.

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.
