Here, we discuss the diagnosis and surgical management of a 38-year-old whose myelopathy was attributed to dorsally compressive HP extending from the lower cerebellar fossa to C3.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 38-year-old male with Sj\u00f6gren\u2019s syndrome presented with cervical pain, upper limb paresis, dysphagia, and left-sided tongue\/palate paralysis. The cervical magnetic resonance (MR) showed a dorsally compressive lower cerebellar fossa to C3 lesion. When the biopsy revealed HP, and once conservative treatment failed, the patient successfully underwent a posterior surgical decompression, lesion debulking, and craniocervical fusion.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nCervical HPs should be diagnosed early on MR, and those with significant myelopathy, aggressively surgically
