Sinonasal organized hematomas are rare, nonneoplastic, benign lesions that usually arise in the maxillary sinus. They are composed of neovascularization in a hematoma and surrounding organizing fibrotic tissue. Factors that may predispose a patient to hematoma formation are vary, and the pathogenesis of the mass is still uncertain. They have the potential for progressive bony erosion and compression of adjacent structures. They are a diagnostic dilemma clinically and radiologically mimicking benign diseases such as inverted papilloma or even malignant neoplasms and causing clinicians undue worry regarding these diagnoses.
