“…Surgery was refused and the patient was managed with carbamazepine. [6] Rizek et al described a woman suffering of the left-sided HFS with tonic contractions of the left face and anterior neck. MRI showed a DVA in the left pons with the large draining vessel in the cerebellopontine angle near the facial nerve REZ.…”

Background: Hemifacial spasm (HFS) is usually caused by vascular compression of the root exit zone (REZ) of the facial nerve. Dual compression of the REZ by veins and arteries is also associated with HFS, but venous origin alone is rarely reported. We present a rare case of HFS caused by the brainstem developmental venous anomaly (DVA) treated with microvascular decompression (MVD). Case Description: A 30-year-old women presented with the left-sided HFS since the age of 18 years. The brainstem DVA was diagnosed by magnetic resonance imaging (MRI) and followed by two attempts of MVD at some other clinics without any improvement. At our hospital, MVD was performed through a left retromastoid craniotomy. Intraoperatively, after detaching the strong adhesions between the cerebellar hemisphere, petrosal dura and lower cranial nerves, and removing the Teflon sponge inserted during the previous operations, the compressing large vein was found, separated from facial nerve REZ and MVD was completed. The postoperative computed tomography angiography and MRI showed the thrombosis of the main trunk of DVA and decompression of the facial nerve REZ. Complete cessation of HFS with hearing preservation was observed with only slight weakness of mimic muscles which disappeared within 3 months after surgery. Conclusion: HFS associated with brainstem DVA is a very rare condition. MVD of the facial nerve REZ with transposition of the large draining vein should be considered as an effective treatment option.

“…Developmental venous anomalies, also known as venous angiomas, are congenital benign anatomic variants which account for over 60% of cerebral vascular malformations; with very low risk for bleeding or for causing symptoms, unless associated with a cavernous malformation. 13 Typically, neurosurgical manipulation of DVAs is generally avoided, due to their relatively benign nature and vital role in drainage of normal brain tissue, fragility and risk of venous infarction from manipulation. 14,15 There is minimal literature on MVD for DVAs associated with HFS, with resolution of HFS symptoms in two 15,16 of the three reported cases; without longterm post-operative followup.…”

“…Developmental venous anomaly is the most frequently found cerebral vascular malformation constituting approximately 60% of all vascular lesions. 15,16 The role of hypertension in the late onset of HFS have been shown in a family, spanning four generations, using MRI and magnetic resonance angiography. 17 Figures 1 and 2 show respective normal MRI of the cranial nerves VII and V.…”

The pathology of the cistern of the cerebellopontine angle is primarily the disease of the nervous and vascular structures that it contains and of the meninges that line it. It appears by the Trigeminal Neuralgia (TN), Hemifacial spasm (HFS), and Glossopharyngeal Neuralgia (GN). We have reviewed the anatomy, pathogenesis, diagnostics and therapy of neurovascular conflicts of cerebellopontine angle. The clinical manifestations of the conflict vary according to the affected nerve. The diagnosis is made on the basis of symptoms but need to be confirmed by imaging. Now-a-days, high-fields Magnetic Resonance Imagings (MRIs) are the standard gold diagnostic method but stay impervious in areas or countries that are less medically equipped. The treatment of neurovascular conflicts of cerebellopontine angle is conservative or interventional. The interventional acts constitute the only curative treatments.
