CASE REPORT: IDIOPATHIC SCLEROSING ORBITAL INFLAMMATION

Idiopathic sclerosing orbital inflammation (ISOI) also known as sclerosing orbital pseudotumor is a rare, idiopathic, chronic, slowly progressive orbital inflammation, characterized by scarring of the tissue that represents a mass effect. The latter leads to bulging of the eye, restriction of ocular movements and visual impairment up to potential loss of vision. It is a subtype of non-specific inflammatory orbital pseudotumor, which both radiologically and clinically mimics a malignant process or other orbital inflammatory disease, and therefore is challenging to diagnose and manage. This case highlights the challenges in diagnosis and management of ISOI.
