Preliminary report on somatostatin receptor imaging in rare endocrine tumours.

Our preliminary experience of Somatostatin Receptor Positive Tumour Scintigraphy (SRPTS) in the management of some rare neuroendocrine tumours is highlighted. Six patients were evaluated using SRPTS. A single patient each with Zollinger-Ellison syndrome, recurrent medullary carcinoma of thyroid and Stage IV neuroblastoma. Two patients with phaeochromocytoma, and one patient with suspected insulinoma were evaluated. SRPTS was useful in three of the six patients studied i.e. patient with gastrinoma, recurrent medullary carcinoma of thyroid and metastatic neuroblastoma. SRPTS although expensive is a useful and cost-effective approach of rare endocrine tumours and it role as a first line tool in the diagnosis is discussed.
