Three Cases of Nasal and Paranasal Hematocele

Abstract

Hematoceles are benign hemorrhagic masses. We report three cases of nasal and paranasal sinus hematocele involving prolonged nasal bleeding. Computed tomography (CT) showed an expanding enhanced lesion with a bone defect at the maxillary sinus and magnetic resonance imaging (MRI) varied lesion intensities. We conducted preoperative angiography and selective embolization to be controlled very effectively enabling surgical bleedings. We conducted endoscopic sinus surgery in 1 case and Caldwell-Luc or Denker procedure in 2 cases. We found preoperative imaging to be vital in determining surgical procedures, with preoperative embolization providing an adjunct in estimating vascular proliferation.
