| Diagnosis | sinonasal organized hematoma |
| Clinical information | 한달 전부터 있어온 오른쪽 epistaxis를 주소로 내원한 54세 남자환자의 PNS CT와 MRI입니다. 가능한 진단은? |
| Discussion | Sinonasal organized hematoma may be mistaken for a malignant or locally aggressive neoplasm by presenting as an expansile soft tissue mass with erosion of the adjacent sinus walls. CT and MR images demonstrated quite characteristic findings, including an expansile soft tissue mass, smooth erosion of bony sinus walls, marked heterogeneous signal intensity with a peripheral rim of hypointensity on T2-weighted MR images, and marked patchy, papillary, or frondlike enhancement on contrast-enhanced CT and MR images.
