Acute Orbital Pseudomeningocele Due to Traumatic Fracture in an Infant

Abstract

Paediatric orbital trauma is uncommon, but it can be associated with significant morbidity. Traumatic pseudomeningocele is an infrequent complication of orbital trauma; it occurs due to an extradural collection of cerebrospinal fluid (CSF) that develops after a dural tear. Herein, we report a case of a seven-month-old male child who presented with eye swelling and suspicion of orbital cellulitis, along with a history of a road traffic accident. He was later diagnosed with traumatic orbital pseudomeningocele and underwent a left frontal craniotomy and duroplasty along with repair of medial orbital pseudomeningocele. Postoperatively, the child remained stable and resolution of proptosis was observed.
