| Popis: | A 43-year-old white male sought treatment for swelling of the left brow, which started after sustaining direct blunt trauma to the left bony orbit 6 months prior. Magnetic resonance imaging with contrast showed a 5.6 × 2.7 mm T1 bright focus at the anterior aspect of the left supraorbital rim. On the postgadolinium fat-saturated axial T1 images, the lesion demonstrated fat signal but was not suppressed in T1 with fat suppression. Upon excision, the lesion was found to be an encapsulated orbital rim lipoma, which was unexpected given the hyperintensity on T1 with fat suppressed magnetic resonance imaging. The lesion did not return after excision. Orbital lipomas are rare benign neoplasms with only a handful of cases in literature. This is the first report of a posttraumatic encapsulated lipoma presenting on the brow or orbit. Although rare, lipomas should be on the differential of post-traumatic lesions affecting the orbit and the orbital rim. |
