Paravertebral pseudotumor in patient with hereditary spherocytosis

As a rare complication in chronic anemic states, the extramedullary hematopoiesis may provide diagnostic and therapeutic challenge. Caused by the insufficiency of the bone marrow with reactivation of quiescent erythropoietic sites, this condition may vary its presentation as a simple radiologic finding to a spontaneous massive haemothorax. In this paper, we report the case of a 61-years-old female patient with hereditary spherocitosys and paravertebral masses, focusing on clinical and radiological findings in CT and MRI to conclude the tumors etiology and provide adequate care.
