INTRODUCTION: Extramedullary hematopoiesis occurs in approximately 15% of cases of thalassemia. Intracranial deposits of extramedullary hematopoiesis are an extremely rare compensatory process in intermediate and severe thalassemia. CASE PRESENTATION: We present an unusual case of an intracranial extramedullary hematopoiesis with a choroid plexus origin in a 34-year-old Caucasian man with beta thalassemia intermedia, who presented with the complaints of chronic headache and rapid progressive visual loss. CONCLUSION: An intracranial extramedullary hematopoiesis, although extremely rare, should be considered as a potential ancillary diagnosis in any thalassemic patient and therefore appropriate studies should be performed to investigate the probable intracranial ectopic marrow before any surgical intervention.
