Primary Extradural Ectopic Orbital Meningioma.
The authors describe a rare case of a primary extradural ectopic meningioma occurring in a 9-year-old female. A review of the literature with respect to clinical presentation, radiographic findings, management, and outcome among similar cases is discussed. Common features that may assist with diagnosing this unusual tumor include absence of bone or optic nerve sheath involvement, presentation at a young age, occurrence in the medial orbit, and sinus asymmetry on radiographic imaging. Preferred method of treatment is complete surgical excision.
