Acute Orbital Pseudomeningocele Due to Traumatic Fracture in an Infant

Treatment of an orbital pseudomeningocele through an eyelid incision

“…2 The development of a PM is variable and can occur anywhere from weeks to years after initial dural insult. 1,2,4 Interestingly, our patient presented with pulsatile proptosis and extraocular motility deficits that occurred within 3 months after his tumor resection.…”

“…Patients with PMs can have variable clinical presentations, including pulsatile or non-pulsatile proptosis, bruit, headache, seizures, epilepsy, decrease vision, diplopia, globe displacement, or defects in extraocular movements. 1 On clinical examination, palpation of the PMs demonstrates a soft, reducible mass that can enlarge with Valsalva maneuvers. 2 The development of a PM is variable and can occur anywhere from weeks to years after initial dural insult.…”

“…3 There are very few reports of orbital PMs in the current literature. 1,4 Here, we report a case of a 17-year-old male status-post gross tumor resection of a pilocytic astrocytoma, who presented with a PM involving the right optic canal and superior orbit and was treated via an anterior orbitotomy.…”

“…2 Although PMs can form due to surgical insults to the dural covering of the brain or spine, they can also occur secondary to trauma or congenital abnormalities. 1,2 Clinical symptoms usually arise when there is mass effect on the surrounding structures. 3 There are very few reports of orbital PMs in the current literature.…”
