Orbital Lipoma: 2 Cases and Review of Literature

This is the authors' abstract. We don't add key points for this paper.

PURPOSE: Lipomas are rare benign tumors of the orbit that can resemble a variety of other orbital masses. We present 2 patients with orbital lipomas and review the literature. METHOD: Retrospective review of clinical charts, imaging studies, and pathology specimens. RESULTS: We encountered 2 patients with lipomas, both presenting with orbital swelling and a mass noted on clinical examination. A well-circumscribed lesion was seen on CT, which on excision was composed of mature fat cells arranged in lobules and surrounded by a diaphanous capsule. CONCLUSIONS: Lipomas arising in the orbit may evoke a range of clinicoradiologic differential diagnoses.
