Fig. 2. Computed tomography (CT) and magnetic resonance images of 34-year-old man with right nasal tumor diagnosed as cavernous hemangioma. A. Early-phase CT image shows mild heterogeneous enhancing tumor (arrow) in right middle meatus. B. Tumor has mild heterogeneous enhancement on coronal delayed-phase image (arrow). Coronal CT image shows erosion of right middle turbinate and lateral nasal wall. C. Mass has heterogeneous high and low signal intensity on T2-weighted axial image (arrow). D. Mass appears with iso-signal intensity (arrow) on pre-contrast T1-weighted axial image. High signal intensity area on tumor margin of T1-weighted image suggests thrombus or thick mucus retention. E. Mass has partial heterogeneous mild enhancement (arrow) on post-contrast T1-weighted axial image. Fig. 2.
