[Paresthesia after climbing-a rare case of a clival mucocele].

We describe an extremely rare case of a clival mucocele and complement the case report with a literature review. A 30-year-old woman presented to the emergency department with unclear neurologic symptoms after bouldering and left-sided hyposensitivity in her face and radial surface of the forearm. Magnetic resonance imaging was suspicious of a clival mucocele, which was confirmed in computed tomography. Endoscopic drainage of the mucocele was undertaken, after which the patient recovered fully.
