Mediastinal pseudotumoral tuberculosis is a rare form of Mycobacterium tuberculosis infection, characterized by marked diagnostic difficulty due to the absence of specific clinical or biological signs and deceptive imaging mimicking a neoplastic pathology. In this article, we report a case of mediastinal pseudotumoral tuberculosis that was treated with a thoracic CT scan and a dorsal MRI scan, which showed a posterior mediastinal lesion process infiltrating the spinal canal and the dorsal soft tissues and suggesting a tumoral or infectious origin. The tubercular origin was retained in the face of presumptive arguments and the patient was treated as lymph node tuberculosis and put on anti-bacillary drugs based on streptomycin, rifampicin, isoniazid and pyrazinamide according to the 2RHZ/4RH protocol with a very good clinical and paraclinical evolution.
