Whole-body 18F-FDG PET/CT scan in a patient with Renal 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 tomography showed:The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The bilateral eyeballs had normal morphology and outlines, clear retrobulbar structures, and symmetrical optic nerves; no abnormal FDG uptake was observed.
Slight thickening of the mucosa in the right sphenoid sinus and bilateral ethmoid sinuses was observed, but the sinus walls were intact, and FDG uptake was absent.
No thickening of the nasopharyngeal wall was observed; the bilateral palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx had normal morphology and structure.
The bilateral parotid and submandibular glands had normal morphology and density, and FDG uptake was physiological.
The thyroid gland had normal morphology and size, but slightly uneven density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Multiple solid nodules with clear borders were observed in both lungs; the largest was located in the posterior segment of the left upper lobe, with a long diameter of approximately 1.4 cm.
FDG metabolism was normal.
A few linear, punctate, and flocculent density shadows were also observed in both lungs; FDG uptake was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
Small lymph nodes were visualized in the bilateral hilar and mediastinal (subcarinal) regions; the largest had a short diameter of approximately 0.8 cm, with some showing slightly increased FDG metabolism (SUVmax = 2.4).
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG uptake was normal.
Bilateral gynecomastia was present.
Small lymph nodes were visualized in both axillae; the largest had a short diameter of approximately 0.6 cm, and FDG metabolism was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
CT scan revealed several slightly low-density lesions in the liver parenchyma with indistinct borders; the largest lesion measured approximately 1.2*1.1 cm.
FDG metabolism was increased, with an SUVmax of 5.1.
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 abnormalities in local FDG uptake.
The pancreas was 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 showed no abnormalities in shape, size, density, or FDG uptake.
The left kidney was absent postoperatively; no abnormal density lesions or lesions with increased FDG metabolism were observed in the surgical area.
The right kidney is normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with slight local thickening of the stomach wall and increased FDG uptake (SUVmax = 3.9).
The intestines are poorly distended, with no obvious thickening of the intestinal wall.
FDG uptake is increased in parts of the colon and rectum (SUVmax = 10.0).
The prostate is normal in shape and size, with high-density shadows seen in the parenchyma, and FDG uptake is not abnormal.
The bladder is poorly distended, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdomen or pelvis.
Bilateral inguinal lymph nodes are visible, the largest measuring approximately 1.7*1.1 cm, with increased FDG metabolism (SUVmax = 5.4).
The spinal alignment is normal, with some vertebral body margin osteophytes.
Following internal fixation of the T5/6/8/9 vertebrae, bone destruction was observed in the T7 vertebral body accompanied by a soft tissue density mass, approximately 6.2*4.3cm in cross-section, with increased FDG metabolism (SUVmax = 4.9).
L4/5 and L5/S1 intervertebral disc bulges were observed, with no abnormal FDG uptake.
L5/S1 intervertebral disc showed pneumatosis and degeneration.
Localized bone destruction was observed in the right acetabulum, with increased FDG metabolism (SUVmax = 3.3).
Increased FDG metabolism was observed in the periarticular areas of both shoulder and hip joints, with an SUVmax = 4.2.
Localized bone destruction was observed in the left iliac wing, with slightly increased FDG metabolism (SUVmax = 1.6).

Impression

1. a. Postoperative left renal cell carcinoma showed no signs of tumor recurrence in the surgical area. b. Postoperative thoracic spine lesion, after internal fixation of T5/6/8/9 vertebrae, a soft tissue mass with increased FDG metabolism at T7, which was larger than before, showed slightly decreased FDG metabolism, suggesting the tumor is still active. c. FDG metabolism of the left iliac wing metastasis was decreased compared to before, suggesting suppressed tumor activity. d. Bilateral inguinal lymph node metastases, liver metastases, and right acetabular bone metastases were all newly developed compared to before.

2. Thyroid gland density was uneven, but FDG uptake was normal; ultrasound follow-up is recommended.

3. a. Multiple chronic inflammatory nodules in both lungs, similar to previous findings. Scattered chronic inflammation and sequelae in both lungs. Slight thickening of the pleura bilaterally. Reactive hyperplasia of the hilar and mediastinal lymph nodes bilaterally.? b. Bilateral gynecomastia. Reactive hyperplasia of the axillary lymph nodes bilaterally.

4. Chronic gastritis, increased FDG metabolism in parts of the colon and rectum, considered physiological uptake or chronic inflammatory changes; please follow up with endoscopy.

5. Prostatic calcification.

6. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. L5/S1 intervertebral disc pneumoconiosis. Bilateral frozen shoulder. Bilateral hip synovitis.

7. No obvious abnormalities seen on cranial scintigraphy. Minor inflammation of the right sphenoid sinus and bilateral 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.
