Massive hemorrhage into intracranial neurinomas

Area of Science:

• Neurosurgery
• Neurology
• Oncology

Background:

• Intracranial neurinomas are typically benign tumors.
• Hemorrhage into these tumors is an uncommon but serious complication.

Observation:

• This report details the 12th documented case of massive bleeding into an intracranial neurinoma.
• The patient's bleeding was precipitated by weight lifting.
• Precipitating factors in other cases included mild head injury and physical exertion.

Findings:

• Tumor size and vascularity are identified as key risk factors for bleeding.
• Patients present with abrupt symptoms including headache, nausea, vomiting, and decreased consciousness.
• Preexisting cranial nerve dysfunction and deficits in adjacent nerves are common.

Implications:

• Computed tomography is essential for diagnosing intracranial hemorrhage and neurinomas.
• Prompt diagnosis and management are critical, as approximately one-fourth of patients may die.
• Despite the risks, many patients can achieve good recovery with appropriate care.
