Fatal tumoural haemorrhage following decompressive craniectomy: a report of three cases

Area of Science:

• Neurosurgery
• Neuropathology
• Oncology

Background:

• Anaplastic cerebral glioma is an aggressive brain tumor requiring surgical intervention.
• Bone and dural decompression are surgical techniques used to relieve intracranial pressure.
• Large and deep-seated tumors present unique surgical challenges.

Observation:

• Three patients with large, deep-seated anaplastic cerebral gliomas underwent bone and dural decompression.
• All patients experienced sudden neurological deterioration within 12 hours post-surgery.
• Postmortem examinations revealed significant intratumoural hemorrhage in all cases.

Findings:

• Surgical decompression may precipitate or exacerbate intratumoural bleeding in anaplastic gliomas.
• The precise mechanisms leading to fatal hemorrhage post-decompression require further investigation.
• Rapid neurological decline and death were directly linked to the observed bleeding.

Implications:

• This study highlights a critical risk associated with decompression surgery for deep-seated gliomas.
• Findings suggest a need for re-evaluation of surgical indications and techniques in such cases.
• Further research is warranted to elucidate the pathophysiology and develop preventative strategies for intratumoural hemorrhage.
