Intrathoracic extramedullary hematopoiesis - a case report

HEMATOPOIESE EXTRAMEDULAR INTRATORÁCICA - RELATO DE UM CASO

Luiza Beatriz Melo Moreira, Alessandro Severo Alves de Melo, Edson Marchiori



ABSTRACT

The authors report a case of a 40-year-old male patient with sickle cell disease who presented with intra-thoracic extramedullary hematopoiesis and paravertebral expansive lesions that appeared as soft tissue density masses on conventional x-ray films. A computed tomography of the chest demonstrated soft tissue density masses in the lower third of the paravertebral spaces. These masses presented well-defined limits, lobulated edges and were heterogeneous due to areas of interposed adipose and soft density tissues. The lung parenchyma had no abnormalities. Computed tomography of the abdomen revealed diffuse hiperdensity and enlargement of the liver that was attributed to hemosiderosis, and an atrophic and calcified spleen due to repeated episodes of infarction.

Keywords: Intrathoracic extramedullary hematopoiesis. Computed tomography. Sickle cell anemia. Posterior mediastinum.

RESUMO

Os autores relatam o caso de um paciente do sexo masculino, de 40 anos de idade, portador de anemia falciforme, que desenvolveu a forma intratorácica de hematopoiese extramedular, apresentando lesões expansivas com densidade de partes moles, localizadas posteriormente, nas goteiras paravertebrais, na radiologia convencional. A tomografia computadorizada do tórax demonstrou massas bem delimitadas, de contornos lobulados, com densidade heterogênea à custa de áreas de tecido gorduroso e de densidade de partes moles, localizadas no terço inferior das goteiras paravertebrais. Os pulmões tinham coeficientes de atenuação preservados. A tomografia computadorizada de abdome revelou importante aumento da densidade e do volume do fígado, atribuídos à hemossiderose, e baço atrófico e calcificado devido a infartos esplênicos de repetição.

Palavras-chave: Hematopoiese extramedular intratorácica. Tomografia computadorizada. Anemia falciforme. Mediastino posterior.
