Following successful resection of both tumors, his brain MRI; CT of the chest, abdomen, and pelvis; and octreotide scan
found no evidence of additional metastatic disease.
showed a well- defined rounded area of increased tracer uptake over centre of left knee joint (Figure-1).
He said the Octreotide Scan
is a type of scintigraphy used to diagnose carcinoid and pancreatic neuroendocrine tumors using SPECT CT scan.
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.
The workup included a bone scan, echocardiogram, and an indium 111 ((111) In) octreotide scan
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.
