Posterior scleritis mimicking orbital cellulitis in an early adolescent patient.

Posterior scleritis is a rare but potentially sight-threatening condition that commonly causes diagnostic confusion due to its variable and perplexing clinical symptoms and signs. We present a case of posterior scleritis presenting with signs of acute orbital inflammation mimicking orbital cellulitis in an early adolescent female. However, subsequent medical imaging revealed signs of posterior vitritis, serous retinal detachment and scleral thickening. Considering the absence of an infective source and the imaging results, the diagnosis of posterior scleritis was confirmed.
