Thoracic manifestations of Neurofibromatosis include intrathoracic posterior mediastinal tumours, meningocoeles, kyphoscoliosis and interstitial fibrosis. Even though mediastinal neurofibromas are common, intrapulmonary neurofibromas are very rare. In this paper, we present a case of intrathoracic neurofibroma with intrabronchial extension. Lesions extending into the bronchial lumen making bronchoscopic diagnosis possible, as in this case is extremely rare. The case is presented because of its rarity.
