Recurrent meningioma.
Single meningiomas are histologically classified as benign tumors, but clearly malignant types have been encountered. The standard mode of management is total macroscopic removal with excision of the dural attachment and abnormal bone, if there is any. Despite this aggressive surgery, recurrence rates of approximately 9% have been reported with the removal of benign tumors, and the rate is much higher with the removal of malignant meningiomas. Recurrence most frequently occurs at the original tumor site and is most often explained by incomplete removal, which, in turn, is a function of the anatomic location of the tumor. Less common are regional recurrences, which may be explained on the basis of the multicentric origin of meningiomas. This theory may also explain the rare entity, "multiple meningioma." This article documents an unexpected regional recurrence of meningioma. The pertinent literature is reviewed.
