Intramedullary cavernous malformations of the spinal cord

Area of Science:

• Neurology
• Neurosurgery
• Vascular Malformations

Background:

• Cavernous malformations (CMs) of the spinal cord are exceptionally rare vascular anomalies.
• Intramedullary CMs represent a subset of these lesions, posing unique diagnostic and therapeutic challenges.

Purpose of the Study:

• To comprehensively review the existing English literature on spinal cord cavernous malformations.
• To analyze the authors' own case series to augment the understanding of these lesions.
• To discuss optimal surgical strategies and treatment outcomes for intramedullary spinal cord CMs.

Main Methods:

• Systematic review of 58 reported cases of spinal cord cavernous malformations from the English literature.
• Inclusion and analysis of 9 original cases managed by the authors.
• Review of clinical presentation, patient demographics, radiographic findings, and histopathological features.

Main Results:

• Consolidation of a significant case series to enhance statistical power for rare lesion analysis.
• Detailed characterization of the clinical and radiological spectrum of spinal cord CMs.
• Evaluation of surgical approaches and their associated outcomes.

Conclusions:

• Spinal cord cavernous malformations require meticulous diagnostic evaluation and tailored surgical planning.
• Surgical intervention remains a key modality for managing symptomatic intramedullary CMs.
• Further research into optimal management strategies can improve patient outcomes and reduce neurological deficits.
