A Haunting Tremor: A Rare Presentation of an Unruptured Arteriovenous Malformation and Review of Related Literature

Tremor is a common phenomenology characterized by an involuntary rhythmic and oscillatory movement. These are formed from any disruption in the dentate-olivary and the basal ganglia-cerebello-thalamic circuits due to neurodegenerative disease, stroke, head injuries, toxins, drugs, systemic illness, or metabolic disorders, and rarely, arteriovenous malformations (AVMs). Brain AVMs, as compared to AVMs in other anatomic locations, are less commonly studied. The pathophysiology, symptomatic correlation, and etiology of these brain AVMs are less reported, hence, current literature reviewed presented patients with a wide spectrum of signs and symptoms which were linked with AVMs of differing risk based on their diagnostic grading. This case report narrates the experience of a 29-year-old female physician presenting with fine high frequency hand tremors later found out to have a parietal AVM. We will discuss AVMs and their consequent course of diagnosis, treatment, and management.
