Positron emission tomography/computerised tomography (PET/CT) scans can mislocalise tumours, leading to incorrect staging. Careful review of PET/CT imaging is crucial for accurate cancer diagnosis and treatment planning.

Area of Science:

  • Oncology
  • Medical Imaging

Background:

  • Combined positron emission tomography/computerised tomography (PET/CT) enhances tumour staging and relapse detection in oncology.
  • Mis-registration errors are a recognized limitation of PET/CT imaging.

Observation:

  • A patient with testicular germ cell tumour experienced mislocalisation of a relapse site on PET/CT.
  • The PET/CT scan incorrectly indicated the tumour was within the T2 vertebral body.

Findings:

  • Subsequent endoscopic ultrasound identified the tumour anterior to the vertebral body.
  • Surgical confirmation validated the accurate tumour location, contradicting the PET/CT findings.

Implications:

  • Artefactual mislocalisation errors in PET/CT imaging can occur.
