Œdème papillaire isolé révélant une sarcoïdose oculaire

La sarcoïdose est une granulomatose multisystémique d'étiologie inconnue, défini par la présence de granulomes épithélioïdes et gigantocellulaires, sans nécrose caséeuse. La sarcoïdose oculaire se manifeste essentiellement par une uvéite antérieure granulomateuse et bilatérale. L'atteinte postérieure au cours de la sarcoïdose oculaire est rare et se manifeste par des périphlébites ou une atteinte choroïdienne. L'œdème papillaire isolé au cours est un tableau atypique d'où la particularité de notre observation. L'atteinte postérieure est un élément de mauvais pronostic menaçant le pronostic visuel, une prise en charge rapide en collaboration avec les pneumologues par corticothérapie systémique permet d'améliorer le pronostic visuel et limiter les complications

To What Extent Can Orbital Cellulitis Emergency Aspect Influence the Diagnosis of Maxillary Sinus Lymphoma?

We present a case of a 46-year-old woman admitted to the emergency department for acute swelling and erythema of the right eyelid for 3 days. Ophthalmological examination was notable for 10/10, P2 best visual acuity, and inflammatory periorbital edema, without exophthalmia nor extraocular motility disturbance. Intraocular pressure was 14 mmHg and fundoscopic examination was not notable for any abnormality. Preseptal cellulitis diagnosis was made, and oral antibiotherapy was immediately started; after 72 hours, the patient did not improve and started complaining of pain on ocular movements. Brain and orbit MRI scan revealed right retroseptal cellulitis associated with homolateral pansinusitis. Intravenous antibiotherapy with oral corticosteroid was started simultaneously leading to full remission but with steroid dependency; 5 days after finishing prednisone, orbital cellulitis symptoms reappeared. The same treatment protocol was given but with corticosteroid tapering over weeks. Nevertheless, steroid dependency persisted. Except for the inflammatory syndrome, complete biological examinations did not disclose any abnormalities. The patient underwent maxillary sinus and fat orbital biopsy; however, histopathological examination was not contributory. Persistence of steroid dependency, chronic atypical rhinosinusitis, normal paraclinical investigations, and age of patient let us suspect lymphoma origin hidden by chronic corticosteroid. We carried out for the second time a maxillary sinus biopsy after stopping steroids, which disclosed primitive non-Hodgkin lymphoma of the maxillary sinus. The aim of this observation is firstly to evoke though it is exceptional the diagnosis of maxillary lymphoma in case of atypical orbital cellulitis and secondly to incite clinicians to be more vigilant in prescribing corticosteroid even if there is an emergency character of orbital cellulitis
