Bone lesion in a patient with transplanted liver for a metastatic carcinoid. The role of somatostatin receptor scintigraphy.

A patient who had previously undergone ileal resection and liver transplantation for a gastroenteropancreatic (GEP) tumor was evaluated with somatostatin receptor scintigraphy (SRS) using 111In-DTPA-D-Phe1-pentetreotide. Eighteen months after surgery, during follow-up procedures, conventional imaging techniques (ultrasound, computed tomography, magnetic resonance imaging) only showed a relapse in the gastropancreatic lymph nodes, while SRS demonstrated skeletal spread. This case report emphasizes the clinical impact of SRS on the management of patients affected by neuroendocrine gastroenteropancreatic tumors.
