Capillary hemangioma of the adult nasal cavity is rare. We report a case which occurred in the right nasal cavity of a 25-years-old woman, together with the multiphase enhanced CT findings. The patients who had a history of recurrent nasal bleeding, had experienced nasal obstruction and swelling during the two-month period prior to presentation, and one month before presentation, spontaneous vaginal delivery occurred. Physical examination revealed the presence of a well-defined round mass, with redness in the right nasal vestibule. The mass showed rim enhancement at early arterial-phase CT scanning, increased enhancement at the late arterial phase, and moderately homogeneous enhancement at the delayed phase.
