Synchronous bilateral bronchial carcinoid diagnosed with combined dual tracer ((18)F-FDG and (68)Ga-DOTATOC) PET/CT scans.

A 38-year-old non-smoker female with unremarkable history presented with an insidious onset of dry cough. Computed tomography revealed two solid round pulmonary lesions, curiously symmetrically located in the middle lobe and in the lingular segment, respectively (Fig. 1). Trans-bronchial needle biopsy was limited by a profuse bleeding and the diagnosis was inconclusive. The radiological differential diagnosis consisted of non-neoplastic disease, synchronous/multifocal bronchial carcinoids and pulmonary metastases from unknown neoplasm.
