title: Imaging of bronchial carcinoid tumors associated to Cushing syndrome with 111In-Octreoscan scintigraphy and immunoscintigraphy with anti-chromogranin monoclonal antibodies. Report of two cases.
abstract: Bronchial carcinoid tumors are neuroendocrine neoplasms capable of expressing somatostatin receptors and of secreting neuromediators such as ACTH and chromogranins. Radiologic appearance is usually non-specific and has to be distinguished from benign pulmonary nodules and other malignant diseases. Standard radiological techniques have limited accuracy in the evaluation of such lesions. Radioisotopic imaging techniques may increase the specificity of diagnostic assessment. The role of immunoscintigraphy with anti-chromogranin A and B monoclonal antibodies (MoAbs) and of 111In-Octreoscan scintigraphy is evaluated in two cases of bronchial carcinoid tumors associated to Cushing syndrome.
