Abstract:
A double-located mediastinal and intrapulmonary cystic teratoma is a rare condition to be considered by thoracic surgeons. Clinical or radiologic diagnosis of a ruptured mediastinal teratoma into adjacent structures may be highly suggestive. An atypical presentation may indicate cautiousness for complete surgical excision. We report the case of a 14-year-old girl presenting with chronic chest pain. The radiologic work-up showed a large cystic mediastinal tumor and a heterogeneous intrapulmonary left upper-lobe lesion. We discuss the radiologic differential diagnosis of this atypical double-located thoracic tumor and the surgical strategy for complete excision.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
