La hematopoyesis extramedular intratorácica aparece en diversas enfermedades hematológicas y se presentan radiológicamente como masas localizadas en el mediastino posterior.

El diagnóstico de esta anomalía puede plantear problemas con otros procesos que cursan igualmente con masas mediastínicas posteriores. El diagnóstico de hematopoyesis intratorácica puede sospecharse si se presentan las siguientes condiciones:

1. Masas de bordes bien definidos, a veces lobuladas, en la región paravertebral torácica sin erosión ni lesiones de estructuras óseas adyacentes.

2. Esplenomegalia o historia de esplenectomía previa.

3. ermedad hematológica crónica, especialmente si se trata de anemia hemolítica congénita.

Extramedullary intrathoracic hematopoiesis occurs in several hematological diseases and on chest films appears as a mass in the posterior mediastinum. The diagnosis may pose problems in differentiation from other processes also presenting masses in the posterior mediastinum. A diagnosis of intrathoracic hematopoiesis may be suspected when there are:

1. ses with well defined margins, which may be lobular, in the paravertebral thoracic region without signs of erosion or lesions in the adjacent bony structures.

2. lenomegaly or a history of previous splenectomy.

3. onic hematological disease, particularly congenital hemolytic anemia.
