Somatostatinomas are associated with calcium deposits called psammoma bodies.[3]
Diagnosis
Fasting plasma somatostatin greater than 30 pg/mL.[citation needed]
SRS (Somatostatin Receptor Scintigraphy) – It is a radio-nucleotide scan by giving Octreotide tagged with Indium111 isotope, which shows an increase in uptake by the tumour cells.[4]
Treatment
Treatment is by chemotherapy with streptozocin, dacarbazine, doxorubicin or by 'watchful waiting' and surgical debulking via Whipple procedure and other resections of the gastrointestinal organs affected.[5]
