Extramedullary hematopoiesis (EMH) is a proliferation of hematopoietic tissue outside the bone marrow. The most affected areas are paravertebral ones. We report the case of a patient with homozygous Hb Lepore, not regularly transfused since the age of four years until the age of 29 years, when paravertebral heterotopic masses were first observed. After about 10 years she started reporting clinical signs suggestive of sinusitis. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) showed heterotopic masses in the ethmoid and in the frontal sinuses.
Involvement of the sinuses of the large facial area represents a rare localization of EMH. Various cases have been reported in patients with thalassemia intermedia, but no case has been reported with HbLepore. The diagnostic gold standard is MRI, which provides highly accurate and clear images. The treatment is based on hydroxyurea and/or an intensive transfusional regime and sometimes on surgery.
