Intracranial tumors are a significant cause of spontaneous intracerebral hematomas, not always malignant. Early diagnosis with advanced imaging is crucial for effective surgical treatment and improved outcomes.

Area of Science:

  • Neurosurgery
  • Neurology
  • Oncology

Background:

  • Intracerebral hematomas are often attributed to hypertension, aneurysms, arteriovenous malformations (AVMs), or cavernomas.
  • The role of intracranial tumors as a cause of spontaneous intracerebral hematomas is less commonly emphasized but significant.

Purpose of the Study:

  • To investigate the incidence and characteristics of intracranial tumors presenting as spontaneous intracerebral hematomas.
  • To compare the tumoral etiology of hematomas with other known causes.
  • To analyze the histological types of tumors associated with bleeding and their clinical implications.

Main Methods:

  • Retrospective analysis of 110 surgically treated cases of intracranial tumors with symptomatic bleeding.
  • Tumor types included glioblastomas, metastases, anaplastic gliomas, low-grade gliomas, meningiomas, and others.

  • Statistical analysis to determine correlations between tumor histology, bleeding incidence, and patient outcomes.

    • Main Results:

    • Intracranial tumors accounted for 4.4% of all surgically treated intracerebral hematomas.
    • Anaplastic gliomas (93%) and meningiomas (62%) showed a higher incidence of bleeding.
    • Benign and low-grade tumors constituted 26% of the hemorrhagic tumors.
    • Postoperative outcomes were primarily influenced by patient age and preoperative clinical status.

    Conclusions:

    • Tumoral etiology is a non-negligible cause of intracerebral hematomas.
    • Hemorrhagic neoplasms are not exclusively malignant; benign and low-grade tumors can also bleed.
    • Advanced imaging like contrast-enhanced CT or MRI is recommended for atypical hematomas to aid surgical planning.
