Interhemispheric subdural hematoma in adults: case reports and a review of the literature

Abstract

The interhemispheric subdural hematoma is a relatively uncommon type of subdural hematoma, especially seen in patients with blood clotting disturbances. When its mass becomes sufficiently large, specific neurological abnormalities such as hemiparesis and signs of the falx syndrome are seen. Treatment can consist of conservative observation or craniotomy and is dictated by the clinical course. Conservative management is the treatment of choice for patients without disturbances of consciousness and for patients with stable clinical conditions. Surgical treatment is necessary in patients with progressive deterioration. Three case reports are presented, as well as a review of 64 cases described in the literature. The salient aspects of this clinical entity are discussed.
