Intramedullary cavernous malformation: A case report

Cavernous malformations are rare vascular anomalies of the central nervous system, occurring in the spinal cord in just 5% of cases. Despite being documented in the literature, intramedullary cavernous malformations are exceedingly rare and often challenging to distinguish from other intramedullary lesions. We report a case of a 42-year-old patient with back pain, right-sided dysesthesias, and impaired proprioception in the distal limbs for approximately 3 months. Magnetic resonance imaging, crucial for differential diagnosis, identified intramedullary cavernous malformations at T11-12. Several conditions can hide the real cause of back pain; however, magnetic resonance imaging can reveal common conditions (such as discal hernia) and rare findings like cavernous malformations. Magnetic resonance imaging remains the study of choice for diagnosing and characterizing intramedullary cavernous malformations.
