Dear Editor,

We have read with great interest the latest paper by Al-Afif and colleagues entitled “Intracranial foreign material granulomas after cranial surgery” recently published in Acta Neurochirurgica ( Wien) [ 3]. The authors performed an analysis of a series of 12 patients with intracranial tumefactive foreign body granuloma (FBG) induced by synthetic material used in a prior cranial surgery documented in their center over a period of 13 years. In all patients, a second surgery was performed to remove the tumor-like lesion which was then examined neuropathologically. The authors concluded that despite its rarity, FBG should be taken into consideration in the differential diagnosis of intracranial mass lesions, especially in cases of suspected tumor recurrence after prior surgery. As stated by the authors, the pathogenesis of FBG still needs further clarification. The authors’ study clearly demonstrates that FBG has a good prognosis after surgical removal. Firstly, we would like...
