Summary

Meningiomas typically progress slowly, but this study reports three cases of acute hemorrhagic onset, including subarachnoid bleeding. These findings highlight rare presentations of brain tumors and diagnostic challenges.

Area of Science:

  • Neurology
  • Neurosurgery
  • Oncology

Background:

  • Meningiomas classically present with a slow, progressive clinical course.
  • These tumors are more commonly diagnosed in middle-aged and older adults, coinciding with higher stroke incidence.
  • Hemorrhagic onset is an atypical presentation for meningiomas.

Observation:

  • The authors present three distinct cases of meningioma with acute hemorrhagic complications.
  • Clinical presentations included subarachnoid hemorrhage, subdural hematoma, and intracerebral hemorrhage.
  • One case involved a petrous bone meningioma presenting with subarachnoid hemorrhage, a potentially novel occurrence.

Findings:

  • Meningiomas can manifest acutely with various types of intracranial hemorrhage.
  • Diagnostic challenges arise due to the atypical presentation mimicking cerebrovascular events.

  • A review of existing literature on meningioma-associated hemorrhage is provided.

    • Implications:

    • Increased awareness of meningiomas as a cause of acute intracranial hemorrhage is crucial for timely diagnosis.
    • Neuroimaging and diagnostic protocols may need to consider meningioma in the differential diagnosis of unexplained hemorrhages.
    • This study contributes to understanding rare meningioma presentations, particularly those involving the petrous bone.
