Giant Recurrent Fronto-temporal Meningioma Presenting with Proptosis in Patient with Skull Defect. A Case Report
Abstract:
Giant asymptomatic meningiomas are rare since these patients usually present with symptoms of increased intracranial pressure and focal signs. We report a case of a giant recurrent asymptomatic meningioma in a patient with a skull defect.
Case Description: A 56-year-old woman visited an ophthalmologist due to a protruding right eye. The patient had a skull defect following meningioma resection 20 years earlier. An MRI revealed a giant recurrent fronto-temporal meningioma extending into the orbit and temporal fossa. The patient had a 10 x12 cm parietofrontal bone defect. She underwent gross tumor resection through an orbitozygomatic approach. Following tumor removal, cranioplasty was performed using methyl acrylate hydroxyapatite to reconstruct the vault and posterior orbital wall. The patient recovered without any neurological deficits.
Conclusion: Giant meningiomas in non-eloquent brain areas typically manifest with intracranial hypertension. In cases involving a preexisting skull defect, the recurrence of a tumor may go unnoticed. This case underscores the importance of regular long-term follow-up for low-grade meningiomas.
