Whole-body 18F-FDG PET/CT scan in a patient with Ovarian Cancer 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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG metabolism was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; and there was no midline shift.
No significant abnormalities were observed in the skull bone; and FDG uptake was not increased.
The bilateral eyeballs had normal morphology and contours; retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and FDG uptake was normal.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
There was no deviation of the nasal septum; no significant thickening of the nasal mucosa was observed; and FDG uptake was normal.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube opening; and the infratemporal fossa and pterygopalatine fossa structures were normal; and FDG uptake was normal.
The palatine tonsils and laryngopharynx showed no abnormalities in morphology or structure, and the parapharyngeal spaces were clear.
The submandibular and parotid glands showed no abnormalities in size, shape, or density, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, and FDG uptake was normal.
The thorax was symmetrical; multiple air-filled sacs were observed in both lungs; small solid nodules were observed in the apical-posterior segment of the left upper lobe, the posterior segment of the right upper lobe, and the right middle lobe, the largest with a long diameter of approximately 0.3 cm, and FDG metabolism was normal.
Scattered linear shadows were observed in the remaining lungs, and FDG uptake was normal.
The pleura was not thickened bilaterally, and there was no pleural effusion bilaterally; FDG uptake was normal.
The trachea was midline, and the trachea and segmental bronchi were patent, with no significant thickening of the tracheal walls or significant stenosis of the lumen.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions, and FDG uptake was not significantly increased.
The heart size was within the normal range, with the cardiac chamber density slightly lower than that of the myocardium.
No pericardial thickening or effusion was observed.
The bilateral mammary glands were dense, with no abnormal density shadows, and FDG uptake was normal.
The liver's shape and size were normal, with smooth liver margins and no widening of the hepatic fissure.
A cystic lesion, approximately 1.1 cm in long diameter, was observed in the left medial lobe of the liver, with absent FDG uptake.
No significant abnormal density shadows were observed in the remaining liver parenchyma, and FDG metabolism was normal.
The hilar region was clearly defined.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder's shape and size were normal, with no thickening of the gallbladder wall, no positive stones or obvious masses, and a clear gallbladder fossa space with normal local FDG uptake.
The pancreas has a clear outline, normal shape and size, no obvious abnormal density shadows, clear surrounding spaces, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen is slightly enlarged, with no abnormalities in density or FDG uptake.
A fat-density shadow, approximately 0.9 cm in long diameter, is seen in the left kidney, with absent FDG uptake; the right kidney is normal in shape and size, with no localized protrusions at the renal border, and plain CT scan shows no obvious abnormal density shadows within the parenchyma, with no obvious abnormal FDG uptake.
The renal pelvis, calyces, and ureters are not widened bilaterally, and no positive stones are seen locally; FDG uptake is not obvious.
The perirenal spaces are clear, and the bilateral adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG uptake.
The esophagus is not dilated, and no increased FDG uptake is seen in the local esophageal wall.
The stomach is reasonably full, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 2.0).
Continuous FDG uptake is observed in parts of the intestine (SUVmax = 6.7).
Following ovarian cancer surgery and chemotherapy, the uterus is absent, and no abnormal FDG metabolism was observed in the surgical area.
A soft tissue nodule is seen on the right side of the pelvis, with increased FDG uptake (SUVmax = 12.0), a long axis of approximately 2.0 cm, and indistinct demarcation from adjacent intestinal segments.
Several small lymph nodes are found around the abdominal aorta and in both inguinal regions, the largest with a short axis of approximately 0.8 cm; no significant abnormalities in FDG metabolism were observed.
No fluid accumulation is seen in the abdominopelvic cavity.
A soft tissue mass is found on the left wall of the bladder, with clear borders, uneven density, and a size of approximately 3.2*2.5*2.9 cm, showing increased FDG uptake (SUVmax = 16.9).
The spinal alignment is normal, with mild cervical lordosis, osteophyte formation at the margins of some vertebral bodies and facet joints, and L4/5 intervertebral disc bulge.
No abnormal uptake was observed on FDG.

Impression

  1. a. Post-ovarian cancer surgery and chemotherapy changes; new soft tissue nodules with increased FDG metabolism in the right pelvic region, highly suggestive of metastasis; further analysis with contrast-enhanced MRI is recommended. b. Reactive hyperplasia of lymph nodes around the abdominal aorta and in both inguinal regions, similar to previous findings.

  2. New bladder lesion with increased FDG metabolism, highly suggestive of bladder cancer; metastasis to be ruled out; further cystoscopy is recommended.

  3. Chronic inflammatory nodules in both lungs, similar to previous findings; follow-up with CT is recommended. Multiple bullae in both lungs. A few old lesions in both lungs. Mild anemia. Bilateral breast hyperplasia.

  4. Liver cyst. Left renal angiomyolipoma, similar to previous findings.

  5. Chronic inflammatory changes in the gastric antrum and part of the intestine; endoscopic follow-up is recommended.

  6. Cervical spondylosis. L4/5 disc bulge.

  7. No abnormalities found on cranial scintigraphy. Inflammatory lymph nodes in the bilateral deep cervical spaces and submandibular region.

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.
