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, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure, with a few punctate low-density shadows in the deep brain regions; no significant abnormalities were observed in FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
A small amount of mucosal thickening was observed in the right maxillary sinus, 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 bilaterally, and there was no narrowing of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; no abnormalities were observed in FDG uptake.
Nasal septum deviation was observed.
Increased FDG metabolism was observed in the right upper alveolar ridge (SUVmax = 11.0).
Increased FDG metabolism was observed in the palate and base of the tongue (SUVmax = 14.4).
No abnormalities were observed in the morphology and structure of the laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uneven density; FDG uptake is normal.
Multiple small lymph nodes are present in the bilateral deep cervical spaces, submandibular region, and supraclavicular region, the largest with a short diameter of approximately 0.5 cm; some show mildly increased FDG metabolism (SUVmax = 3.9).
Scattered, patchy areas of increased density with blurred margins are seen in the upper and middle lobes of the right lung and the lower lobe of the left lung; FDG metabolism is increased (SUVmax = 5.7).
Scattered linear shadows are also seen in both lungs; FDG uptake is normal.
No thickening of the right pleura is observed; there is no pleural effusion or pneumothorax bilaterally.
Calcification of some arterial walls (including coronary arteries) is present.
The cardiac silhouette is normal.
Post-esophagectomy, FDG metabolism at the esophageal anastomosis site is increased (SUVmax = 8.5).
An enlarged lymph node, approximately 0.8 cm in short diameter, is seen beside the trachea in the upper mediastinum; FDG metabolism is increased (SUVmax = 13.6).
A soft tissue nodule measuring approximately 0.9 x 1.3 cm was observed in the left lower pleural region, with increased FDG metabolism (SUVmax = 10.8).
Multiple small lymph nodes were seen in the retroperitoneum, the largest being approximately 0.6 cm in short diameter, with increased FDG metabolism (SUVmax = 7.9).
No significant effusion was observed in the abdomen or pelvis.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A mixed-density mass measuring approximately 3.6*2.7cm was observed in the middle of the right kidney, with background FDG uptake.
A low-density lesion approximately 0.8cm in length with clear borders was observed in the left kidney, along with a slightly higher-density nodule approximately 1.4cm in length; both showed absent FDG uptake.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
The stomach was not distended, but the gastric wall was thickened, with increased FDG metabolism (SUVmax = 8.2).
Intestinal distension was poor, with continuous increased FDG metabolism in the descending colon and sigmoid colon (SUVmax = 12.6).
The prostate was of normal size, containing calcifications, but FDG uptake was not abnormally increased.
The bladder was generally distended, with no obvious positive stones.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulging.
FDG metabolism was increased throughout the skeleton (SUVmax = 7.3).
Fracture of the 8th rib on the left side with callus formation.

Impression

1. a. Post-esophageal cancer surgery, increased FDG metabolism at the anastomosis site, likely due to inflammatory or physiological uptake; please follow up with gastroscopy to rule out other possibilities. b. Metastasis to the right paratracheal lymph nodes in the upper mediastinum. Metastatic tumor in the left lower pleural region. c. Possible retroperitoneal lymph node metastasis. Reactive hyperplasia of bilateral deep cervical, submandibular, and supraclavicular lymph nodes.

2. Right renal mass; further enhanced MRI is recommended. Left renal cyst (including complex cysts). Prostatic calcification.

3. Infection in the upper and middle lobes of the right lung and the lower lobe of the left lung. Scattered post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

4. Physiological or inflammatory uptake of the gastric wall and parts of the intestine; please follow up with endoscopy.

5. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge. Reactive hyperplasia of the entire bone marrow. Old fracture of the left 8th rib.

6. A few ischemic lesions deep in the brain. Age-related brain changes.

7. Minor chronic inflammation of the right maxillary sinus. Nasal septum deviation. Inflammatory uptake in the right upper alveolar bone, palate, and base of the tongue.

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.
