Spindle cell typical carcinoid tumor (well-differentiated neuroendocrine carcinoma) diagnosed by electromagnetic navigation bronchoscopy with cytologic rapid on-site evaluation

摘要

A 50-year-old man was incidentally found to have a 2-cm right lung nodule on chest radiographs, while being worked up for pneumonia. His past medical history was noncontributory, except for having quit smoking 20 years previously. A PET-CT scan showed an oval-shaped 2.0 X 1.7 cm mildly hypermetabolic (SUV of 2.8) mid-field right middle lobe nodule, adjacent to an area of linear ate-lectasis and mild bronchiectasis. No mediastinal or hilar lymphadenopathy was identified. No other intrathoracic, head and neck or intraabdominal lesions were identified. The nodule did not appear to be accessible through trans-thoracic CT-guided biopsy due its close proximity to the pulmonary vessels.
