From the case:
Sarcoidosis (PET-CT)
CT guided biopsy of the anterior mediastinal nodes revealed sarcoidosis.
Case Discussion
Sarcoidosis is characteristically FDG-avid, and PET-CT has been shown to have high sensitivity for thoracic disease.FDG-PET-CT may be useful for
- identification of occult sites of disease
- identifying a suitable target for diagnostic biopsy
- gauging active inflammatory disease in patients with prolonged symptoms
- assessing response to treatment
