Intracranial hemorrhages are important clinical events necessitating early diagnosis and treatment as they might cause significant mortality and morbidity. Knowing clinical signs is important in early diagnosis. In this study we present an 18 year old male patient who had admitted to our clinic with a history of jumping into the sea that resulted in a head trauma nearly two months ago and who developed diplopia and headache two weeks ago. Following neurological, ophthalmological and radiological evaluations; the case was diagnosed as chronic subdural hematoma accompanied by unilateral isolated abducens nerve palsy. The patient was operated and this resulted in resolution of his symptoms. This case demonstrated us that isolated 6th cranial nerve palsy might develop as an initial symptom in chronic subdural hematomas.
