Idiopathic Granulomatous Orbital Inflammation.

Idiopathic granulomatous inflammation is regarded as a histopathologic variant of anorbital pseudotumor and has a similar clinical presentation and treatment. However, the differentialdiagnosis including sarcoidosis, Wegener's granulomatosis, trauma, and infectionmust be ruled out. We present a 77-year-old man with a biopsy-proven lacrimal gland granulomatousinflammation of an unknown origin. Management by surgical debulking via ananterior orbitotomy achieved a good result with minimal complications.
