BACKGROUND The etiological diagnosis of intracranial hypertension is quite complicated but important in clinical practice.Some common causes are craniocerebral injury,intracranial space-occupying lesion,subarachnoid hemorrhage,and hydrocephalus.When a patient presents with intracranial hypertension,the common causes are to be considered first so that other causes would be dismissed.With the morbidity lower than 9%,neuromelanin is very rare.Common symp-toms include nerve damage symptoms,epilepsy,psychiatric symptoms,and cognitive disorders.CASE SUMMARY We present a patient with melanoma which manifested with isolated intracranial hypertension without any other neurological signs.A 22-year-old male had repeated nausea and vomiting for 2 mo with Babinski sign(+)on both sides,nuchal rigidity,and subarachnoid hemorrhage.He had been diagnosed with melanoma and was given surgery and whole-brain radiation.Ultimately,the patient died 2 mo later.CONCLUSION Malignant melanoma should be taken into consideration in the differential diagnosis of intracranial hypertension.
