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, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure, with a few patchy low-density shadows in the bilateral basal ganglia; FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
The eyeballs were symmetrical and without significant abnormalities.
The right maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened; FDG metabolism was increased on both sides of the nasopharyngeal walls (SUVmax = 8.9); the bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was not abnormal.
The bilateral palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was not abnormal.
Scattered cystic lucent shadows were observed in both lungs, with partial bronchial cystic dilatation visible in the right middle and lower lungs.
A nodule measuring approximately 1.0 cm was visible in the apex of the left lung, showing obvious lobulation and spiculation, with increased FDG metabolism (SUVmax = 5.3).
Mixed ground-glass nodules and patchy shadows were seen in the posterior segment of the right lower lobe and the anteromedial basal segment of the left lower lobe, with a long diameter of approximately 0.5 cm, and no abnormal FDG uptake was observed.
Multiple solid small nodules with clear borders were also seen in both lungs, with a long diameter of approximately 0.2-0.5 cm, and no increased FDG metabolism was observed.
Linear shadows and calcifications were visible in the right upper lung and both lower lungs.
There was pleural effusion on the left side, with localized thickening of the pleura in both oblique fissures.
Multiple thickened areas with soft tissue shadows were visible in the left pleura (left lower lung pleura and left lower costophrenic angle pleura), the largest measuring approximately 3.3*1.2 cm, with increased FDG metabolism (SUVmax = 10.0).
Destruction of the left lateral aspect of the T10 vertebral body and the left 10th and 11th posterior ribs with soft tissue formation, showing increased FDG metabolism (SUVmax = 10.1).
Multiple enlarged lymph nodes were observed in the bilateral hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region, the largest with a short diameter of approximately 0.7 cm, showing mildly increased FDG metabolism (SUVmax = 4.9).
Calcification of arterial walls (including coronary arteries) was present.
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth liver margins and no widening of the hepatic fissure.
A small cystic low-density lesion of approximately 0.6 cm was observed in the left lobe of the liver, with no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with a localized soft tissue nodule in the mid-sigmoid colon measuring approximately 1.9*2.1 cm, showing increased FDG metabolism (SUVmax = 15.2).
Strip-like FDG uptake is visible in the lower sigmoid colon and rectum.
Multiple small lymph nodes are visible at the root of the mesentery, with no significant increase in FDG uptake.
The prostate is normal in size, with punctate calcifications, and no abnormally increased FDG uptake.
The bladder is generally distended, with no obvious positive stones.
Calcification of the tunica vaginalis in the left testis, and hydrocele in both testes.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes.

Impression

1. a. A nodule at the left apex of the lung, highly suggestive of primary lung cancer; please correlate with clinicopathology. Enlarged hilar and mediastinal lymph nodes bilaterally with mildly elevated FDG metabolism suggest metastasis; follow-up examination after treatment is recommended. b. Left pleural effusion, multiple thickenings of the left pleura with elevated FDG metabolism suggest multiple pleural metastases. c. Destruction of the left portion of the T10 vertebral body and the left 10th and 11th posterior ribs with soft tissue mass, elevated FDG metabolism, suggest metastasis.

2. Scattered emphysema and bullae in both lungs; cystic dilatation of some bronchi in the right middle and lower lobes. Mixed ground-glass nodules in the posterior segment of the right lower lobe and the anterior-medial basal segment of the left lower lobe, with no elevated FDG metabolism, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules; multiple chronic inflammations and old lesions in both lungs (possible old pulmonary tuberculosis in the right upper lobe). Localized thickening of the pleura in both oblique fissures. Calcification of some arterial walls (including coronary arteries).

3. Localized soft tissue nodules in the mid-sigmoid colon with increased FDG metabolism, suggestive of a polyp with potential malignancy; please confirm with colonoscopy pathology. Inflammatory changes in the lower sigmoid colon and rectum, reactive hyperplasia of lymph nodes at the root of the mesocolic colon.

4. Small cyst in the left lobe of the liver. Prostatic calcification. Calcification of the tunica vaginalis on the left side of the testis, bilateral hydrocele.

5. Spinal osteophyte formation.

6. Lacunar ischemic foci in the bilateral basal ganglia. Age-related brain changes. Chronic inflammation of the nasopharynx. Minor inflammation of the right maxillary sinus.

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.
