Overview
Since paragangliomas including carotid body tumor are of neuroendocrine origin, they may have somatostatin surface receptor which can be detected as an area of intense radio-tracer uptake by the Indium-111 octreotide scan. This modality may be helpful in the diagnosis of multicentric or metastatic disease. It also may be used after the surgery to look for a residual tumor.
Other Imaging Findings
Since paragangliomas including carotid body tumor are of neuroendocrine origin, they may have somatostatin surface receptor which can be detected as an area of intense radio-tracer uptake by the Indium-111 octreotide scan. This scan may be helpful in the diagnosis of:[1]
- Multicentric tumor
- Metastatic disease
- Residual tumor after the surgery
The scan is sensitive for tumors greater than 1.5 cm.
