Chest Wall Metastasis of Ileal Carcinoid Tumor Detected With In-111 Octreotide Scan

Carcinoid tumors are potentially malignant, generally being related to regional lymph node and liver metastases. Rarely, metastases to other sites such as the breast have been reported. Radiolabeled peptide analogs such as In-111 octreotide play a useful role in the localization and potentially in the management of carcinoid tumors and their distant metastases. The authors report a case of ileal carcinoid tumor with unusual presentation of a chest wall metastasis. Chest radiograph was normal. Thoracic CT scanning showed a soft tissue mass in the chest wall. In-111 octreotide scintigraphy revealed increased uptake in the anterior chest wall and liver. A biopsy of the lesion showed carcinoid tumor.
