Bronchial carcinoid tumors are an uncommon cause of recurrent pneumonia in young patients. Diagnosis is determined from imaging studies, bronchoscopy, and histological confirmation, and treatment is generally surgical. Two cases are reviewed in order to examine the value of 111In-DTPA-Phe-octreotide (111In-pentetreotide) scintigraphy in the pre-surgical evaluation of these patients. After a suspicious area was observed in other tests (standard X-ray, CT), a neuroendocrine tumor was diagnosed using this technique and the presence of regional or distant disease was ruled out. Comparison with the less valuable 18F-FDG PET (carried out in one of the cases) highlights the usefulness of SPECT-CT, which performs notably better in terms of the localization and characterization of findings.
