Leptomeningeal cyst of the orbital roof in an adult: case report and literature review.

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.
