[Periocular skin depigmentation, developing after removal of a cranioorbital meningioma]

The paper gives a case of periocular skin depigmentation developing after neurosurgical treatment for hyperostotic cranioorbital meningioma. It also shows a natural history of the tumor, as seen in a series of sequential CT scans. The patient was operated on 13 years after the onset of the disease. Five months following surgery, a well-defined periocular depigmentation appeared on the operated side. This remained unchanged on a follow-up visit at months 12. As follows from the presented review of known cases of periocular depigmentation, the described postneurosurgical depigmentation has not yet been reported.
