A hematocele in the maxillary sinus-CT and MRI studies-

Abstract

CT and MRI images were evaluated in the 4 cases of hematocele in the maxillary sinus. A CT scan demonstrated a soft tissue density in the unilateral maxillary sinus and nasal cavity. MRI images showed a heterogeneous mass lesion and a thickened mucosa in the maxillary sinus. An MRI scan proved to be very useful for the preoperative diagnosis of a hematocele in the paranasal sinuses.
