Imaging findings
Extensive pleural disease, including fluid, calcified pleural plaques, and large focal tissue deposits in the extrapleural space. A circumscribed fluid collection is noted in the soft tissues of the chest wall. Some areas exhibit unusual growth patterns, and culture of the chest wall fluid was positive for Mycobacterium tuberculosis complex.
Key takeaways
Disseminated Mycobacterium bovis infection, particularly after intravesical BCG therapy for bladder cancer, can present with unusual extrapulmonary manifestations. These can include pleural and chest wall disease, such as abscesses and soft tissue collections, even years after the initial therapy.
