This is a case of a six-year-old girl who presented with prolonged vomiting and headache, indicating intracranial hypertension. Although she showed no signs of acute otitis media, computed tomography of the brain revealed mastoiditis and cerebral venous thrombosis. Because she had abducens palsy and intracranial hypertension with papilledema but no abnormal cerebrospinal fluid findings, she was diagnosed with otitic hydrocephalus caused by masked mastoiditis.
