[Spontaneous subarachnoid hemorrhage in infancy -- first symptom of a medulloblastoma (author's transl)]

The death of a 10 years old male patient was due to a clinically asymptomatic tumor in the posterior fossa with the initial symptom of a spontaneous subarachnoid hemorrhage. Even if those cases are rare, symptom-free subtentoiral tumors have to be considered as possible etiological factors of subarachnoid hemorrhage unrelated to intracranial aneurysm or a-v malformation.
