Quadruple vessel involvement at root entry zone in trigeminal neuralgia

Area of Science:

• Neurology
• Neurosurgery
• Vascular Neurology

Background:

• Trigeminal neuralgia (TN) is a debilitating neuropathic pain disorder.
• Vascular compression of the trigeminal nerve is a common etiology for TN.

Observation:

• A rare case of TN involving quadruple vessel compression at the trigeminal nerve root entry zone is presented.
• The compressing vessels included a dilated basilar trunk, anterior inferior cerebellar artery, superior cerebellar artery, and superior petrosal vein.

Findings:

• Multiple major posterior circulation vessels were found in close proximity to the trigeminal nerve.
• The neuovascular conflict was specifically located at the nerve's root entry zone.

Implications:

• This anatomical configuration presents unique technical challenges for surgical interventions.
• Understanding multiple vessel compression is crucial for predicting surgical outcomes and patient prognosis.
