Whole-body 18F-FDG PET/CT scan in a patient with Cervical 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, a whole-body PET/CT scan was performed.
The whole-body scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
Thickening of the left maxillary sinus mucosa was observed, but the sinus wall was intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and no abnormalities were observed in FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in shape and size, with slightly uneven density; no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A mixed ground-glass nodule with clear borders, measuring approximately 1.8*1.4cm, was observed in the posterior segment of the left upper lobe.
Multiple solid nodules were present in both lungs, the largest being located in the lateral basal segment of the right lower lobe, with a long diameter of approximately 0.9cm.
FDG uptake was normal in all nodules.
Scattered linear opacities were observed in both lungs.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were observed in the hilar and mediastinal regions.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
A punctate calcification was observed in the left breast; the remaining breasts showed no significant abnormalities, and FDG metabolism was normal.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
CT scan showed decreased liver parenchymal density (CT value approximately 48 HU); FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened; and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened; and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended; the stomach wall was not significantly thickened; and FDG uptake was normal.
The intestines were poorly distended; the intestinal wall was not significantly thickened or showed masses; and FDG uptake was physiological.
A roundish low-density lesion was seen in the uterine body, with localized increased density in the center, measuring approximately 5.7*4.8cm; FDG metabolism was absent.
The cervix and cervical canal showed heterogeneous density; two nodular areas showed increased FDG metabolism, with SUVmax=5.6.
A cystic low-density lesion with septa and clear borders was observed in the right adnexal region, the largest measuring approximately 11.6*8.8cm.
Increased FDG uptake was observed in parts of the cyst wall and septa (SUVmax = 1.6).
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The bladder was generally full, with no obvious positive stones.
The spinal alignment was normal, with some vertebral body margin osteophytes.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Heterogeneous density in the cervix and cervical canal with increased FDG metabolism suggests a high probability of neoplastic lesions. b. Possible effusion or cystic mass in the uterine body. c. Cystic mass in the right adnexa, with increased FDG uptake in part of the cyst wall and septa, suggests a possible cystadenoma, with local malignancy to be ruled out. Further enhanced MRI is recommended, and hysteroscopic biopsy may be necessary.

2. a. Mixed ground-glass nodule in the apical-posterior segment of the left upper lobe, with low FDG metabolism, suggests a possible chronic inflammatory nodule, but lung cancer cannot be ruled out. Close observation with HRCT is recommended. b. Multiple solid chronic inflammatory nodules in both lungs. Scattered chronic inflammation and remnants in both lungs. Punctate calcification in the left breast. Calcification of some arterial walls.

3. Mild fatty liver.

4. Partial vertebral osteophyte formation.

5. No obvious abnormalities seen on cranial scintigraphy. Chronic inflammation of the left maxillary sinus.

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.
