Early symptoms of chordoma of the cranial slope are mainly headaches. Because the tumor in this area is close to the brainstem, it can also show symptoms of brainstem compression, with bilateral adductor nerve involvement as the main feature. If the tumor invades the cerebellum and cerebral bridge as the disease progresses, hearing impairment, tinnitus and vertigo can occur. If the tumor continues to develop into the nasal cavity or the back wall of the pharynx, it can lead to poor nasal ventilation, nasal congestion, local pain, and also lead to nasopharyngeal symptoms such as purulent or bloody nasal discharge or difficulty in swallowing, and sometimes a nasopharyngeal mass can be seen on examination. For cranial slope chordoma once the diagnosis is clear, early surgery combined with radiation therapy is recommended, because the average life expectancy of chordoma is about 6.3 years and only early medical intervention can improve the survival rate of patients.
