A Rare Case of Periorbital Edema and Conjunctival Prolapse Due to Traumatic Intraorbital CSF Leakage.

Posttraumatic herniation of brain and CSF into the eyelid is a rare entity with few reported cases in the literature. A 5-year-old girl presented to us with severe periorbital edema and conjunctiva prolapse after 7 days of head trauma. Clinical suspicion of CSF leakage accumulating in lid and periorbita was suspected. CT and MRI scan brain showed multiple comminuted frontal bones, orbital roof, and orbital rim fractures with contused brain tissue herniation through the dural defect. Craniotomy with dural repair was done after which patient improved and within 2 weeks both periorbital edema and conjunctiva prolapse subsided. [ABSTRACT FROM AUTHOR]
