ABSTRACT
Objective: To present the case of a leptomeningeal cyst involving the orbital roof
in an adult. Design: Case report and literature review. Setting: Tertiary referral
center. Summary: A 47-year-old female with a remote history of a skull fracture at
3 years of age presented with increasing headaches and retro-orbital pain. A computed
tomogram and magnetic resonance image revealed a leptomeningeal cyst of the orbital
roof. Results: Only one previous leptomeningeal cyst of the orbital roof has been
reported in an adult. Surgical excision of the lesion was performed and follow-up
imaging 18 months after the operation revealed no evidence of recurrence. Conclusion:
Although extremely rare, adult patients can develop growing skull fractures or leptomeningeal
cysts of the orbital roof. Such lesions should be included in the differential diagnosis
when a patient presents with orbital pain or exophthalmos and a history of head trauma
as a child.
