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, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; local density and FDG uptake were normal; midline structure shift was normal.
The bilateral eyeballs showed normal morphology and outline; retrobulbar structures were clear; optic nerves were symmetrical; FDG uptake was normal.
No thickening was observed in the paranasal sinus mucosa; sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; bilateral pharyngeal recesses were symmetrical; Eustachian tube openings were not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; bilateral parapharyngeal spaces were clear; FDG uptake was normal.
Bilateral palatine tonsils were full; FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
Bilateral salivary glands showed no abnormal visualization.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
The thorax was symmetrical bilaterally; miliary nodules were observed in the right upper lobe; FDG uptake was normal.
Calcifications were observed in the left upper lobe; linear opacities were observed in both lower lobes.
The trachea was midline; the trachea and all lobar and segmental bronchi were patent.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions; FDG uptake was normal.
No pleural thickening was observed bilaterally; a small amount of pleural effusion was observed bilaterally.
The cardiac silhouette was normal.
The esophagus was not dilated; the esophageal wall was not significantly thickened or swollen; FDG uptake was normal.
No abnormal density shadows were observed in the bilateral mammary glands; FDG uptake was normal.
The liver was normal in shape and size; the liver margins were smooth; the hepatic fissures were not widened.
No significant abnormal density shadows were observed in the liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, the gallbladder wall was not thickened, and no positive stones or obvious masses were observed.
FDG uptake was normal.
The pancreas showed no abnormalities in shape, the parenchyma showed no obvious abnormal density shadows, 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 showed no abnormalities in shape or size, the renal parenchyma showed no obvious abnormal density shadows, and FDG uptake was normal.
The renal pelvis, calyces, and ureters showed no widening, and no positive stones were observed.
Both adrenal glands showed no abnormalities in shape or density, and FDG uptake was normal.
Gastric distension was poor, with increased FDG uptake in some gastric walls (SUVmax = 3.5).
Bowel preparation was poor; no obvious masses were observed in the intestinal wall, but increased FDG uptake in some intestinal segments (SUVmax = 5.8).
Bilateral adnexal regions showed cystic-solid masses with indistinct borders; the left mass was larger, measuring approximately 7.8*4.4cm.
The solid component showed increased FDG uptake (SUVmax = 17.8).
The uterus was shrunken, and a nodular mass with increased FDG uptake (SUVmax = 11.9) measuring approximately 2.2*1.7cm was observed in the uterine body.
The bladder was poorly filled, but no positive stones or obvious masses were observed.
Multiple lymph nodes were observed in the retroperitoneum, mesentery, and bilateral anterior diaphragmatic groups, the largest with a short diameter of approximately 0.5cm; some showed increased FDG uptake (SUVmax = 5.0).
Multiple thickenings were observed in the subdiaphragmatic, abdominopelvic peritoneum, and pelvic floor fascia, with multiple solid nodules and masses showing increased FDG uptake (SUVmax = 22.1).
Fluid accumulation was observed in the abdominopelvic cavity.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebral bodies.
A high-density nodule measuring approximately 1.3*0.8cm was observed at the level of the T11 vertebral body within the spinal canal.
Increased FDG uptake was observed, with SUVmax=3.8, and localized bony narrowing of the spinal canal was observed.

Impression

1. Bilateral adnexal region cystic-solid lesions with increased FDG metabolism in the solid component; nodular FDG hypermetabolic foci within the uterus; multiple lymph nodes in the retroperitoneum, mesentery, and bilateral prediaphragmatic groups showing some with increased FDG metabolism; thickening of the subdiaphragmatic, abdominopelvic peritoneum, and pelvic floor fascia with increased FDG metabolism. Considering all of the above, this is likely a malignant tumor, possibly originating from the ovary with multiple metastases. Metastatic lesions in the adnexa cannot be ruled out. Please combine clinical findings with enhanced MRI for comprehensive analysis. Abdominal and pelvic effusion.

2. Chronic inflammatory nodule in the right upper lobe of the lung. Calcification in the left upper lobe of the lung, fibrosis in both lower lobes of the lungs. Small amount of bilateral pleural effusion.

3. Increased FDG metabolism in parts of the gastric wall and intestines, considered physiological uptake or chronic inflammation.

4. High-density nodule at approximately the T11 vertebral level within the spinal canal with increased FDG metabolism, considered a possible meningioma. Enhanced MRI follow-up is recommended. Mild osteophyte formation in some vertebral bodies.

5. No obvious abnormalities were found on cranial imaging.

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.
