Whole-body 18F-FDG PET/CT scan in a patient with Pancreatic 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.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were 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 parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The bilateral thyroid glands showed relatively uniform density, and FDG metabolism was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region; FDG metabolism was normal.
Multiple ground-glass nodules of similar size were observed in both lungs, the largest measuring approximately 0.5 cm in length.
Multiple small solid nodules were also observed in the remaining lungs, the largest also approximately 0.5 cm in length.
FDG uptake was normal in all nodules.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the hilum or mediastinum bilaterally.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
Both breasts were relatively dense, and FDG metabolism was normal.
Scattered multiple low-density nodules with indistinct borders were observed in the liver, the largest measuring approximately 2.8 2.3 cm, with increased FDG uptake (SUVmax = 8.9).
Several cystic lesions were observed in the left lobe of the liver, the largest measuring approximately 1.7 1.4 cm; FDG uptake was normal.
The main portal vein was not significantly widened, 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.
A soft tissue mass measuring approximately 6.2 3.8 cm was observed in the neck and body of the pancreas, with blurred peripancreatic fat spaces, involvement of the celiac trunk, increased FDG uptake (SUVmax = 8.2), and atrophy of the pancreatic tail.
Multiple small lymph nodes were observed between the superior mesenteric artery and the hepatogastric ligament, the largest with a short diameter of approximately 0.4 cm, showing mild FDG uptake (SUVmax = 1.5).
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
A cystic lesion measuring approximately 0.6 cm in diameter was observed in the right kidney, with no abnormal FDG metabolism.
The left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
The left adrenal gland was full in shape, measuring approximately 1.3 0.8 cm, with increased FDG metabolism (SUVmax = 3.6).
The stomach was poorly filled, but the stomach wall was not significantly thickened, and FDG uptake was not significantly abnormal.
The intestines were poorly filled, but the intestinal wall was not significantly thickened or lumped, and FDG uptake was physiological.
The uterus was absent post-operatively, and FDG uptake was not abnormally increased.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, and no obvious positive stones were observed.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The pelvic floor peritoneum showed slight linear thickening, with mild FDG uptake (SUVmax = 1.6).
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, calcification of the nuchal ligament, L3/4 and L4/5 intervertebral disc bulging, and gas density shadows within the L4/5 and L5/S1 intervertebral discs, but FDG uptake was not abnormal.
Focal FDG concentration was observed in the right femoral head (SUVmax = 3.8).

Impression

  1. a. Masses in the neck and body of the pancreas, with increased FDG metabolism, suggestive of pancreatic cancer involving surrounding fat spaces and the celiac trunk. Multiple intrahepatic metastases. Right femoral head metastasis. b. Multiple small lymph nodes between the superior mesenteric artery and the hepatogastric ligament, with mild FDG uptake, suggestive of reactive lymph node hyperplasia; follow-up CT scan recommended to rule out metastasis. c. Strip-like thickening of the pelvic floor peritoneum, with mild FDG uptake; metastasis to be ruled out; clinical correlation recommended.

  2. a. Multiple nodules in both lungs, with no abnormal FDG uptake, suggestive of inflammatory nodules, with some mixed metastases to be ruled out; close follow-up CT scan recommended. b. Multiple ground-glass nodules in both lungs, with no abnormal FDG metabolism, suggestive of atypical adenomatous hyperplasia or inflammatory nodules.

  3. Small cyst in the left lobe of the liver. Right renal cyst. Left adrenal hyperplasia is likely; follow-up examination recommended. Postoperative absence of the uterus.

  4. Spinal degenerative changes, L3/4 and L4/5 intervertebral disc bulging, L4/5 and L5/S1 intervertebral disc pneumatosis and degeneration.

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.
