Whole-body 18F-FDG PET/CT scan in a patient with Lung 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 punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the bilateral ventricles were symmetrical, and there was no midline shift.
Normal morphology and contour of the bilateral eyeballs; clear retrobulbar structures; symmetrical optic nerves; no abnormal FDG metabolism.
No thickening of the paranasal sinus mucosa; intact sinus walls.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses or Eustachian tube openings; normal structures of the infratemporal fossa and pterygopalatine fossa; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism was observed in the oropharynx and laryngopharynx.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG metabolism is normal.
Small lymph nodes are visible in the bilateral deep cervical spaces, submandibular region, and submental region, the largest being approximately 0.6 cm in short diameter, with FDG metabolism normal.
An irregularly lobulated soft tissue density mass is seen in the right middle lobe near the diaphragm and subpleural region, with relatively clear borders, measuring approximately 3.2*1.4*2.1 cm in cross-section, showing increased FDG metabolism (SUVmax=6.3); several solid nodules are also seen in both lungs, with clear borders, the largest located in the anterior segment of the right upper lobe, approximately 1.2 cm in long diameter, some showing increased FDG metabolism (SUVmax=3.4).
Calcification is also present in the right middle lobe.
A few linear and flocculent density shadows are also seen in both lungs, with FDG metabolism normal.
There is no pleural effusion or pneumothorax bilaterally.
Small lymph nodes behind the trachea and vena cava in the mediastinum are visible, the largest with a short diameter of approximately 0.6 cm.
Some show slightly increased FDG metabolism, with SUVmax = 2.5.
The cardiac silhouette appears normal.
Bilateral mammary glands show dense fibrous tissue, with no significant abnormalities in FDG metabolism.
The liver appears normal in shape and size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan shows no significant abnormal density shadows in the liver parenchyma, and FDG metabolism is normal.
The main portal vein shows no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is absent post-operatively.
The pancreas appears normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG metabolism is normal.
The spleen appears normal in shape, size, density, and FDG metabolism.
A splenic nodule with a long diameter of approximately 0.5 cm is seen adjacent to the spleen, with no abnormalities in FDG metabolism.
Both kidneys are normal in shape and size.
A cystic low-density lesion with relatively clear borders and a long diameter of approximately 1.0 cm is seen in the parenchyma of the upper pole of the left kidney.
FDG metabolism is absent.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG metabolism is not significantly abnormal.
No significant abnormalities are seen on bilateral adrenal gland imaging.
No esophageal dilation is observed, and no significant thickening or mass is seen in the esophageal wall.
FDG metabolism is not increased.
The stomach is generally full, with slight thickening of the antral wall and a slightly increased FDG metabolism (SUVmax = 2.3).
The intestines are poorly full, with increased FDG metabolism in parts of the colon and rectum (SUVmax = 4.9).
Focal increased FDG metabolism is observed in the anal region (SUVmax = 5.3).
The uterus is normal in shape and size, with no abnormal density shadows and no abnormal FDG metabolism.
A low-density nodule measuring approximately 2.7*2.1cm was observed in the right adnexal region, with absent FDG metabolism.
No obvious abnormalities were seen in the left adnexal region.
The bladder was poorly filled, but no obvious positive stones were observed.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneum.
No obvious fluid accumulation was seen in the abdomen or pelvis.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies.
Destruction of the S1-2 vertebral bodies was observed with the formation of a soft tissue density mass measuring approximately 7.4*4.7cm, with increased FDG metabolism and an SUVmax of 3.8.
Schmorl's nodes were observed at the lower margin of the T12 vertebral body and the upper margin of the L2 vertebral body.
The L4/5 and L5/S1 intervertebral discs bulged, but FDG metabolism was normal.
The L5/S1 intervertebral disc showed pneumatosis and degeneration.

Impression

1. a. A mass in the right middle lobe near the diaphragm pleura with increased FDG metabolism, highly suggestive of peripheral lung cancer; please correlate with clinicopathology. b. Several metastatic tumors in both lungs. Metastatic tumors in the S1-2 vertebral bodies. c. Calcification in the right middle lobe. A few post-inflammatory remnants in both lungs. Reactive hyperplasia of mediastinal lymph nodes. Bilateral breast hyperplasia.

2. Absence after cholecystectomy. Accessory spleen. Possible left renal cyst. Right ovarian cyst.

3. Chronic antral gastritis. Increased FDG metabolism in parts of the colon and rectum, suggestive of physiological uptake or chronic inflammatory changes; please correlate with endoscopic follow-up. Possible hemorrhoids.

4. Degenerative changes in the spine. Schmorl's nodes at the lower margin of T12 vertebral body and the upper margin of L2 vertebral body; L4/5 and L5/S1 intervertebral disc bulges; L5/S1 intervertebral disc pneumatosis and degeneration

5. Deep lacunar infarcts in the brain, MRI follow-up recommended; reactive hyperplasia of bilateral deep cervical intervertebral spaces, submandibular and submental lymph nodes.

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.
