Natural history and surgical management of incidentally discovered low-grade gliomas Clinical article

1 Patients with low-grade gliomas most commonly present with seizures.6 These lesions are rarely discovered as incidental findings during brain imaging for unrelated complaints or research studies.9,11,19,29,32 It is not clear how to best manage incidental asymptomatic LGGs, although some believe that there is no benefit to early resection.2,18,23 However, a recent study has suggested that the surgical removal of incidental LGGs may in fact increase survival, possibly by allowing for a greater extent of resection.20 We sought to verify these findings by examining our own experience with incidental LGGs treated using resection.
