Introduction: Solitary fibrous tumors (SFTs) are rare neoplasms, with a mesenchymal origin that mainly affects the pleura. The SFTs from extrapleural sites are uncommon. This tumor in the nasal cavity is initially asymptomatic, and due to its growth, the patients may present nasal obstruction and epistaxis; due to compression also visual and neurological disturbances. Methods: In this report, we present a 40-year-old male patient with a diagnosis of SFTs of the paranasal sinus with intracranial and dural invasion. Results: This patient has no medical history and presented with bilateral nose blocked. Contrast-enhanced computed tomorgrahic scan showed a mass involving the right nasal cavity, causing deviation of the nasal septum and compromised anterior and posterior sinus. The magnetic resonance revealed the involvement of the right muscle superior oblique, and the intracranial component moves toward superior the right frontal lobe, with adjacent dural enhancement areas. The lesion was removed completely with an endoscopic approach with no recurrences two years after. Conclusion: The SFTs of the nasal cavity and paranasal sinus are rare, with 38 cases reported in the literature, and only one case presents intracranial and dural invasion. They present mainly in the fourth and fifth decades of life and occur equally between men and women. To our knowledge this is the second case of SFTs involving the nasal cavity and paranasal sinuses with intracranial and dural compromise worldwide, and the first in Latin America. Solitary fibrous tumors (SFTs) should be a potential differential diagnosis in tumors with clinical as well as pathological complicated characterization due to the rarity of presentation at this location.
