Proptosis due to Isolated Intra-orbital Meningocele-a case Report

Congenital orbital wall defects are very rare bone abnormalities that can cause protrusion of intracranial contents into the orbit. The protrusion of the meninges, which encompasses cerebrospinal fluid (CSF), result in a condition known as the orbital meningocele, a rare cause of pulsatile proptosis. Here, we present a 4-year-old female with left eye proptosis referred to our clinic. On magnetic resonance imaging (MRI), a cystic structure was present. The patient underwent surgery for cyst removal. CSF leakage was noted during surgery. Computed tomography (CT) scan revealed a bony defect in the sphenoid greater wing and the resulting meningocele. Craniotomy surgery was performed to close and fill the defect
