Per operative localization of a carcinoid tumour of the breast using indium-111 pentetreotide and a nuclear surgical probe

Abstract
A 69-year-old woman presented with a single enlarged lymph node in the left axilla. Clinical examination and other investigations, including various imaging methods, failed to reveal the primary tumour. However, indium-111 pentetreotide scan revealed a site of uptake in the anterior region of the left thorax. Peroperative imaging with t111In-pentetreotide confirmed the tumour uptake and use of a nuclear surgical probe allowed precise localization of the tumour, which was completely resected.
