Whole-body 18F-FDG PET/CT scan in a patient with Breast 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, with no abnormal density shadows in the brain parenchyma, and no abnormal FDG metabolism.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG metabolism were normal, and there was no midline shift.
The morphology and outline of both eyeballs were normal, the retrobulbar structures were clear, and FDG metabolism was normal.
No significant thickening of the paranasal sinus mucosa was observed bilaterally; the sinus walls were intact, and FDG metabolism was normal.
No significant thickening of the soft tissue on both sides of the nasopharyngeal wall was observed; the pharyngeal recesses were symmetrical bilaterally, and FDG metabolism was normal.
The palatine tonsils were full bilaterally, with physiological FDG uptake.
The morphology and structure of the laryngopharynx were normal, and the parapharyngeal space was clear.
The parotid and submandibular glands were normal in size, shape, and density, with normal FDG uptake.
The thyroid gland was normal in shape and size, with no obvious abnormal density shadows, and normal FDG metabolism.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, and submental region, with normal FDG uptake.
Multiple small solid nodules, approximately 0.2-0.3 cm, were observed in both lungs, with normal FDG metabolism.
Scattered patchy linear shadows and nodular foci, as well as calcifications, were seen in both lungs, more prominent in the right upper lobe, with normal FDG metabolism.
Interstitial changes were observed in the lower lobes of both lungs.
Slight pleural thickening was observed in parts of both sides, but no significant pleural effusion was seen bilaterally.
No enlarged lymph nodes were seen in the hilum of both lungs; small mediastinal lymph nodes were visible, some with higher density, the largest with a short diameter of approximately 0.5 cm, with no significant increase in FDG metabolism.
The heart size was normal.
Post-operatively, right breast cancer was present, with the right breast absent.
No abnormal FDG metabolism was observed in the surgical area.
A dense soft tissue shadow, approximately 1.5*2.8cm in cross-section, was observed in the lateral aspect of the left breast, with indistinct margins and thickened adjacent skin.
FDG metabolism was elevated, with an SUVmax of 3.1.
Multiple enlarged lymph nodes were observed in the left axilla, right supraclavicular region, and pretracheal space.
The largest, located in the left axilla, measured approximately 1.8*3.3cm.
FDG metabolism was elevated, with an SUVmax of 5.0.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no elevated FDG metabolism.
Gastric distension was adequate, with slight thickening of the antral gastric wall and a mildly elevated FDG metabolism (SUVmax = 2.3).
Intestinal distension was unsatisfactory; no local masses were observed, and FDG uptake in some intestinal segments was physiological.
Intrahepatic and extrahepatic bile ducts are dilated, and the gallbladder is significantly enlarged; the pancreatic duct is dilated, and the density of the pancreatic head, neck, and body is uneven, with increased FDG metabolism (SUVmax = 6.0), and uptake ranges of approximately 2.1*1.9cm and 2.01.2cm, respectively.
A cystic density shadow with septa is visible in the pancreatic neck, measuring approximately 1.1*2.2cm, with absent FDG metabolism.
The pancreatic body and tail are significantly atrophied.
Multiple enlarged lymph nodes are seen adjacent to the right iliac vessels, the largest with a short diameter of approximately 1.2cm, showing increased FDG metabolism (SUVmax = 15.9).
The spleen is generally normal in shape and size, with no abnormalities in density or FDG metabolism.
The bilateral adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG metabolism.
The bilateral kidneys are normal in shape and size, with no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormalities in FDG metabolism.
No widening of the renal pelvis, calyces, or ureters was observed bilaterally, and no positive calculi were seen in the affected areas.
The bladder was poorly filled, but no positive calculi were found within the bladder cavity.
The uterus was normal in shape and size, and FDG uptake was normal.
No abnormal density shadows or increased FDG uptake were seen in the bilateral adnexa.
No significantly enlarged lymph nodes were seen bilaterally in the inguinal canals, and FDG metabolism was not increased.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margins and facet joints showing osteophyte formation, but no abnormal FDG uptake was observed.
The L5-S1 intervertebral space was slightly narrowed, and the endplates at the relative vertebral margins were roughened.
L4/5 and L5/S1 intervertebral disc herniation was observed, compressing the dural sac.

Impression

1. a. Left breast mass with increased FDG metabolism, consistent with breast cancer. b. Multiple lymph node metastases in the left axilla. Possible multiple lymph node metastases in the right supraclavicular and pretracheal spaces. c. Post-operative changes following right breast cancer resection.

2. a. Pancreatic duct dilation, uneven density in the head, neck, and body of the pancreas, with increased FDG metabolism; cystic shadow in the pancreatic neck, with absent FDG metabolism; IPMN is highly likely, but malignancy cannot be ruled out. Please combine clinical findings with contrast-enhanced MRI. Right iliac lymph node metastasis is highly probable. b. Intrahepatic and extrahepatic bile duct dilation, gallbladder enlargement.

3. Multiple chronic inflammatory nodules in both lungs. Scattered chronic inflammation and remnants (including plaque nodules and calcifications) in both lungs, more prominent in the apical segment of the right upper lobe. Interstitial changes in the lower lobes of both lungs. Slight thickening of the pleura in some areas. Reactive hyperplasia of small mediastinal lymph nodes.

4. Chronic inflammatory changes in the gastric antrum; endoscopic re-examination is necessary if required.

5. Degenerative changes in the spine. L5 and S1 endplate inflammation. L4/5 and L5/S1 intervertebral 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.
