technetium-tc-99m-medronate and Tracheal-Diseases

Tracheobronchopathia osteochondroplastica (TO) is a rare disorder with unknown aetiology. We report one case of TO in a patient with non-Hodgkin pulmonary lymphoma and benign epidermal and trichylemmal cysts on the periorbital region and scalp. To the authors' knowledge, the coincidence of these processes has never been described before. The case was evaluated with conventional X-ray, computed tomography, magnetic resonance imaging, fibre-optic bronchoscopy with 2 months interval, histopathological evaluation, Tc-99 m MDP bone scintigraphy and microbiological studies including PCR testing of bronchial biopsy and lavage specimens for Mycobacterium tuberculosis. Additionally, case reports of TO in the Turkish literature are summarized.

A case of primary tracheobronchial amyloidosis is reported. A 61-year-old man presented with a 2-year history of intermittent hemoptysis. Chest X-ray and CT scanning showed tracheobronchial thickening. Bronchoscopic examination revealed diffuse tracheobronchial narrowing, and tracheobronchial biopsy detected amyloid deposits. Both 99mTc-HMDP planar and SPECT images were obtained in this patient. Coronal SPECT images revealed more precisely that the activity was not in the thoracic cage but in the bilateral hilar region. Localization of the amyloid deposits could be better determined on SPECT images than on planar images.
