Although any BT can bleed, the frequency and type of bleeding varies across tumor types.Materials and methods: We aimed to retrospectively review our experience with 55 patients with BTs presenting with ICH.Results: Signs of increased intracranial pressure were the most common symptoms. The temporal lobe was the most common lesion site (n = 22). Hemorrhages were mainly confined to the tumor margins (HCTs) (n = 34). Extensive intraparenchymal hemorrhages (EIHs) were mainly associated with moderately/severely decreased levels of consciousness (LOCs) (n = 15/16). High-grade glioma (HGGT) (n = 25) was the leading pathological diagnosis followed by metastasis (MBT) (n = 16/55). The hemorrhage type was associated with the pathological diagnosis of the tumor. Patients with HGGT (n = 19/25) and MBT (n = 9/16) mainly presented with HCTs, whereas low-grade gliomas (LGGT) primarily caused EIHs (n = 6/7).Conclusions: Hemorrhagic presentation is a rare occurrence in BTs. Among all, MBT and HGGT are responsible for majority of the cases. Importantly, despite their relatively benig ncharacteristics, LGGTs mainly result in extensive parenchymal destruction once they bleed. Maximum surgical resection of hemorrhagic BTs and decompression of the affected brain regions followed by histological confirmation of the diagnosis should be the main goals of treatment in cases with hemorrhagic BTs.(c) 2022 Published by Elsevier Espana, S.L.U. on behalf of Sociedad Espanola deNeurocirug ' ia.eninfo:eu-repo/semantics/closedAccessCerebellar pilocytic astrocytomasLow-grade gliomaIntracerebral hemorrhageIntracranial hemorrhageFollow-upHematomaHemorrhagic brain tumorHigh-grade glial tumorIntracranial hemorrhageMetastatic brain tumorLow-grade glial tumorTumor cerebral hemorragicoTumor cerebral metastasicoNeurosciences & neurologySurgeryArticle00105823670000117718534410.1016/j.neucir.2022.06.001
