Abstract

A 79-year-old woman with gradually worsening left nasal obstruction, purulent rhinorrhea and severe headaches for 6 months admitted to the hospital. A gray-white and huge mass occupying the left nasal cavity was found in physical examination. CT revealed a soft-tissue-density mass in the left nasal cavity with erosion of adjacent bone structures. On T2-weighted MR images, the lesion showed homogenous extreme low signal intensity. The patient underwent successful surgical removal of huge sinonasal soft tissue mass measuring 50 × 45 × 40 mm. The final diagnosis of fibroma was made histologically. MR imaging studies showed characteristic signal intensities corresponding to histopathological components. To the best of our knowledge, this is the first report regarding the MR imaging findings of huge nasal fibroma in the English literature.
