Idiopathic periorbital lipogranuloma
Author: tula romina
ePoster Number: 270
Purpose
To report a case of idiopathic periorbital lipogranuloma.
Methods
A 59-year-old female presented with a 1-year history of a palpable mass in the lower internal left orbital rim. She was treated for cholesterolemia and denied any facial or ophthalmic surgery, injections, or trauma. Axial CT scan showed a soft tissue mass without bone compromise in the lower internal left orbital rim. The axial RMI T1 and T2 weighted images showed a isointense heterogeneous mass.
Results
Excisional biopsy was performed. Histological findings showed fat vacuoles with necrosis surrounded by multinucleated cells and a chronic lymphoid infiltrate which are main characteristics of lipogranulomatosis.
Conclusion
Discussion: Orbital and periorbital lipogranulomas are benign tumors which were reported most frequently in association with trauma, autologous fat injections, paraffin intradermal injections, leakage of intraocular silicone into the surrounded orbital tissue, subtenon steroid injection, trans canalicular ointment injection after laser canaliculoplasty and after endonasal sinus surgery. Idiopathic periorbital lipogranuloma are extremely rare. Most cases reported in literature were associated to previous mentioned causes. We present a case of idiopathic periorbital lipogranuloma without any previous condition. Histological findings were characteristic of lipogranuloma: fat vacuoles with necrosis surrounded by multinucleated cells and a chronic lymphoid infiltrate. Clinically it presents swelling, edema, and/or a non-tender mass.Treatment with systemic anti-inflammatories, and systemic or intralesional steroids were described but in most cases surgical removed is needed.
Conclusion: This type of granulomatous inflammatory reaction and posterior necrosis fat occurs for various reasons. We should discard every known cause with an exhaustive questioning and consider idiopathic cause. Surgical removal is the best treatment option in most cases.
