Fast growing recurrent grade I meningioma: A rare case report

Meningiomas are mostly regarded as benign tumours, accounting for 13% to 26% of all primary intracranial tumors1. According to 2016 World Health Organization (WHO) classification, meningiomas are classified into grade I (benign), II (atypical), and III (anaplastic).2 Meningioma are neoplasms derived from arachnoidal (meningothelial) cells. These lesions can occur in people of any age but commonly present in middle age. Women are more likely to develop a meningioma, with a female/male ratio of approximately 2:1 intracranially and 10:1 in the spine.3 Even after complete removal, meningiomas have been estimated to recur in 10 to 32% of the cases within 10 years. However, recurrences in grade 1 meningiomas are rare and occur after long duration.4 We herein report a case of grade 1 meningioma that recurs very fast, within the duration of 1 yr and the recurrent size of the tumor was approx three times the size of the primary one. To our knowledge, very few cases in the literature have been reported with such a fast-growing grade 1 meningioma
