Case #1Surgical approach decision / Neurosurgery / Spine

📋 Case data

Symptoms/syringomyelia + degree of descentSymptomatic (classic cough/strain-induced occipitocervical pain, brainstem/cerebellar/cord signs) or with syringomyelia

Data is taken from this pathway's reviewed node text. Work through the pathway step by step.

Step 1 / 1 · Symptoms/syringomyelia + degree of descent

Symptoms or syringomyelia? Degree of tonsillar descent?

💡 Tonsillar descent ≥5 mm is the imaging criterion, but whether to operate depends on symptoms and syringomyelia, not the millimeters of descent alone.
