Diagnostic difficulties of antero-superior mediastinal masses with cardiac infiltration. Endovascular bioptic alternative approach.

The diagnosis of mediastinal masses is challenging due to the variety of possiblepathologies , and its definitive diagnosis is mainly confirmed by histological evaluation. Sometimes some lesions may have a greater intravascular rather than mediastinal development and the collection of a biopsy sample becomes even more complex. In these cases endovascular catheter biopsy is helpful in the collection of the necessary biological material, having to adapt to the type of surface and consistency of the mass to be analyzed. Endovascular catheter biopsy was performed with a biliary forceps to sample a mediastinal mass with greater endovascular and cardiac development, with a hard and difficult to sample surface. The histological result was diagnosed with non-hodgkins lymphoma.
