Zusammenfassung:Orbital inflammatory disease(OID) represents a collec tion of inflammatory conditions affecting the orbit. OID is a diagnosis of exclusion, with the differential diagno sis including infection, systemic inflammatory conditions and neoplasms, among other conditions. Inflammatory conditions in OID include dacryoadenitis, myositis, cel lulitis, optic perineuritis, periscleritis, orbital apicitis, and a focal mass. Sclerosing orbital inflammation is a rare condition with a chronic, indolent course involving dense fibrosis and lymphocytic infiltrate. Previously though to be along the spectrum of OID, it is now considered a distinct pathologic entity. Imaging plays an importan role in elucidating any underlying etiology behind orbita inflammation and is critical for ruling out other condi tions prior to a definitive diagnosis of OID. In this re view, we will explore the common sites of involvemen by OID and discuss differential diagnosis by site and key imaging findings for each condition.
