He said the Octreotide Scan
is a type of scintigraphy used to diagnose carcinoid and pancreatic neuroendocrine tumors using SPECT CT scan.
did not show significant uptake within these lesions.
Functional studies include indium-111-labeled octreotide scan
and fluorodeoxyglucose positron emission tomography (FDG-PET) (1, 3).
was also performed looking for a carcinoid tumor.
We monitored the patient closely using regular imaging to identify any early recurrence of tumor using a whole-body MIBG diagnostic scan and a whole-body indium-1 1 1 octreotide scan
A complete metastatic work-up was then conducted including serum markers (serotonin, Chromogranin A, urine 5-HIAA) and a total body octreotide scan
, which were negative.
However, due to retrospective nature of this analysis, lack of availability of PET or octreotide scan
at our institute and significant cost outside, these test were not carried out in our patients.
The workup included a bone scan, echocardiogram, and an indium 111 ((111) In) octreotide scan
When these routine studies fail, octreotide scan
can be considered, which may increase the yield.
On the basis of an octreotide scan
, TIO can be classified as OctreoScan-positive tumors or OctreoScan-negative tumors.
We obtained an octreotide scan
, which revealed multiple focal areas of isotope uptake in both the right and left lobes of the liver; this finding is consistent with somatostatin subtype-2-expressing hepatic metastatic disease.
Polypectomy was considered curative for carcinoid, since a subsequent octreotide scan
falied to reveal any area of increased uptake suggestive of metastasis.
