Whole-body 18F-FDG PET/CT scan in a patient with Esophageal 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:Normal brain morphology and structure, with patchy low-density shadows in the deep cerebral regions bilaterally; FDG uptake was not significantly abnormal.
Widening of some ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Normal eyeball morphology and contours bilaterally; clear retrobulbar structures; symmetrical optic nerves bilaterally; FDG uptake was not significantly abnormal.
Thickening of the mucosa of the bilateral maxillary and ethmoid sinuses; intact sinus walls.
No thickening of the nasopharyngeal wall was observed; FDG uptake was normal; symmetrical pharyngeal recesses bilaterally; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; FDG uptake was normal.
Normal thyroid morphology and size; homogeneous density; FDG uptake was normal.
Post-esophageal cancer surgery: Changes in the thoracic cavity and stomach; thickening of soft tissue in the hypopharynx and cervical esophagus; increased FDG uptake (SUVmax = 18.5); lesion length approximately 4.1 cm, involving the right pyriform fossa.
Soft tissue nodules and masses are seen in the right deep cervical space, with indistinct borders and unclear demarcation from the right parotid gland; some contain nodular high-density shadows, the largest measuring approximately 4.5*3.3 cm, with increased FDG uptake (SUVmax = 12.9).
Multiple small lymph nodes are seen in the left deep cervical space, the largest with a short diameter of approximately 0.6 cm; some show increased FDG uptake (SUVmax = 3.8).
Multiple solid miliary nodules are seen in the left lung, with normal FDG uptake.
Scattered linear shadows and a few patchy hazy shadows are seen in both lungs; scattered air-filled cavities are seen in both lungs.
The trachea is midline, and the trachea and segmental bronchi are patent.
No thickening of the pleura was observed bilaterally, and there was no effusion or pneumothorax in either pleural cavity.
Multiple lymph nodes were seen behind the vena cava and in the aortic window, the largest with a short diameter of approximately 0.9 cm; FDG uptake was normal.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissures.
Several cystic lesions were seen in the liver parenchyma, the largest with a long diameter of approximately 0.8 cm; calcification was seen in the left lobe of the liver; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was shrunken, containing multiple nodular dense shadows with a rough wall; 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; FDG uptake was normal.
Spleen morphology and size normal, density and FDG uptake normal.
A soft tissue mass with indistinct borders, measuring approximately 5.1*4.8*5.3cm, was observed in the left kidney, with increased FDG uptake (SUVmax=7.2).
The right kidney morphology and size normal, FDG uptake normal.
No widening of the renal pelvis, calyces, or ureters was observed, and no positive stones were seen within them.
The left adrenal gland was slightly enlarged, while the right adrenal gland morphology and density normal, FDG uptake normal.
Bowel preparation poor, no obvious mass in the intestinal wall, increased FDG uptake in some intestinal segments (SUVmax=6.2).
Prostate morphology and size normal, transverse diameter approximately 4.1cm, no obvious abnormal density in the parenchyma, no significantly increased FDG uptake.
Bladder distension poor, no obvious positive stones seen within.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
FDG uptake was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Scoliosis was present, with osteophyte formation at the margins of some vertebral bodies, L4/5 disc bulging, and pneumothorax in the L4/5 and L5/S1 discs.
Multiple rib fractures were observed on the right side.

Impression

1. a. Postoperative changes after esophageal cancer surgery; thickening of soft tissue in the hypopharynx and cervical esophagus, increased FDG metabolism, suggestive of malignancy; please refer to pathology reports. b. Right deep cervical lymph node metastasis. Reactive hyperplasia of left deep cervical lymph nodes is highly probable.

2. Left renal mass with increased FDG metabolism, highly probable of renal cell carcinoma; please provide a comprehensive analysis with contrast-enhanced MRI.

3. Chronic inflammatory micronodules in the left lung. Chronic inflammation and sequelae in both lungs, emphysema. Reactive hyperplasia of small mediastinal lymph nodes. Partial arteriosclerosis (including coronary arteries).

4. Liver cysts. Liver calcifications. Gallstones, chronic cholecystitis. Left adrenal hyperplasia.

5. Increased FDG metabolism in parts of the intestine, suggestive of physiological uptake or chronic inflammation.

6. Scoliosis with degeneration. L4/5 disc bulge, L4/5 and L5/S1 disc pneumatosis and degeneration. Multiple old rib fractures on the right side.

7. Bilateral deep lacunar infarcts, age-related brain. Chronic inflammation of the bilateral maxillary and ethmoid sinuses.

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.
