| Diagnosis | Organized hematoma |
| Clinical information | F/78 C.C> Left proptosis |
| Discussion | 해설: There is a well-defined mass-like lesion showing isointensity on T1WI and heterogenous signal intensity on T2WI in the extraconal space of the left orbit. The lesion shows heterogeneous enhancement on postcontrast T1WI. Organized hematoma (OH) is an uncommon, nonneoplastic benign condition that can be locally aggressive. Without careful evaluation of all of the imaging features, this may be mistaken for a malignant lesion both clinically and radiologically. It can result from various causes of hemorrhage with chronic hematoma formation, followed by the process of organization through fibrosis and neovascularization. |
