Spinal arteriovenous malformations (AVMs), especially if they have a large venous component, can be significantly affected by hormonal changes during pregnancy. This case describes a pregnant woman with a history of previous extrauterine pregnancy, dizziness and neck pain, sudden and rapidly progressive tetraipostenia secondary to a previously undiagnosed spinal AVM at the third cervical (C3) level. Cervical pial AVM is an extremely rare condition, it can present with progressive myelopathy or acute hemorrhage (subarachnoid or intramedullary). The progressive change in iconographic aspects and the “fluctuating” trend of symptoms during this period of pregnancy are analyzed and described. The hormonal changes of pregnancy make pregnant woman particularly susceptible to complications of spinal vascular malformation, with extreme difficulty in the decision-making process. This case report demonstrates the key role of magnetic resonance imaging and digital subtraction angiogram in the diagnosis and following diagnostic-instrumental monitoring.
