Subconjunctival and orbital silicone oil granuloma (siliconoma) complicating intravitreal silicone oil tamponade.

Lee JH, Kim YD, Woo KI, Kong M - Case Rep Ophthalmol Med (2014)

Bottom Line: On MRI examination, subconjunctival mass and intra- and extraconal orbital mass around superior rectus muscle were observed.Excision of subconjunctival and orbital mass was performed.Histopathologic examination showed multiple silicone oil vacuoles surrounded by foreign body giant cells and fibrosis, which confirmed silicone oil granuloma.

ABSTRACT
A 30-year-old male, who underwent previous pars plana vitrectomy and silicone oil tamponade due to endogenous endophthalmitis originated from Klebsiella liver abscess, was referred for evisceration. At 2 months after vitrectomy with silicon oil tamponade, conjunctival chemosis and ocular pain were aggravated. Diffuse eyelid swelling and large subconjunctival mass with lipid droplets were noted. On MRI examination, subconjunctival mass and intra- and extraconal orbital mass around superior rectus muscle were observed. Excision of subconjunctival and orbital mass was performed. Histopathologic examination showed multiple silicone oil vacuoles surrounded by foreign body giant cells and fibrosis, which confirmed silicone oil granuloma. In a patient with suspicious melting sclera in diseases such as endophthalmitis, large silicone oil granuloma may be complicated in a rapid fashion after intravitreal silicone oil tamponade due to silicone oil leakage.

Magnetic resonance image (MRI). (a), (b) T1- and T2-weighted images reveal a large septate cystic mass in subconjunctival and orbital space with low signal intensity. (c), (d) The mass is located in the superior orbit accompanied by inflammatory reaction showing heterogenous enhancement in Gd-enhanced T1-weighted images.

Mentions: Orbital magnetic resonance image (MRI) examination showed shrinkage of the eyeball and large subconjunctival and orbital mass. The mass was located in superior part of the orbit between levator muscle and eyeball, surrounding superior rectus muscle. It demonstrated septate cystic form with low signal intensity in T1- and T2-weighted image and heterogenous enhancement in Gd-enhanced image (Figure 2).
