Summary
A rare sacral dural arteriovenous fistula (dAVF) can mimic neuropathy. Prompt diagnosis and endovascular embolization effectively treated this condition, improving patient symptoms.
Area of Science:
- Neuroscience
- Vascular Surgery
Background:
- Sacral dural arteriovenous fistulas (dAVFs) are exceptionally rare vascular malformations.
- The pathophysiology and clinical presentation of sacral dAVFs remain poorly understood.
Observation:
- A 70-year-old male presented with progressive, right-dominant bilateral lower limb sensory disturbances.
- Clinical course and electrophysiological results mimicked multiple mononeuropathy.
Findings:
- Angiography revealed a sacral dAVF located at the right intervertebral foramen (L5-S1).
- Endovascular embolization successfully treated the sacral dAVF.
Implications:
- Sacral dAVFs can present with symptoms and electrophysiological findings similar to multiple mononeuropathy.
- This rare condition is treatable and should be considered in the differential diagnosis of lower extremity disorders.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
