Traumatic Isolated Interhemispheric Fissure Subdural Hematoma Under Anticoagulant Therapy in an Elderly Patient: A Case Report

Acute subdural hematomas are often encountered over the convexity of the cerebral hemisphere, but the localization of the interhemispheric fissure is rare. Interhemispheric fissure subdural hematoma (IHSDH) is usually accompanied by subdural hematoma, intracerebral hemorrhages, while its isolated form is extremely rare. They are usually benign due to the fact that they are usually treated conservatively and are not directly correlated with an increase in intracranial pressure. In cases which develop under the use of antiplatelets or anticoagulants, it is recommended to discontinue the drug for a while so that the hematoma does not grow in size. There is no clear answer in which patients the drug will be discontinued and how long the use will be interrupted.
