Quick Summary

Syringobulbia is a condition where a cyst, known as a syrinx, forms in the brainstem. It is often associated with syringomyelia, a chronic disease involving cysts near the spinal cord or brainstem.1

Symptoms of syringobulbia can include tongue atrophy, difficulty swallowing, and loss of pain and temperature sensation in the face. These symptoms arise from the cyst interrupting nerve fibers and compressing pathways in the brainstem. The exact cause is unknown, but it's believed to be a developmental defect. While there is no cure, surgical drainage of the cyst can help manage the condition.12
