Inter-hemispheric scissure, a rare location for a traumatic subdural hematoma, case report and review of the literature.

Subdural interhemispheric hematomas (ISH), though not really rare, are quite an uncommon complication of head traumas. This condition is more frequent in childhood, where it is generally considered as a part of a more complex syndrome, called 'Shaken Children Syndrome', usually pointing out child abuse. Although a head injury is very often considered the cause (in about 80-90% of the cases), possible predisposing factors such as coagulopathies, alcohol abuse or anticoagulant therapy can also be considered. Furthermore, as the rupture of an intracranial aneurysm has also occasionally pinpointed as a possible cause, this event should be kept in mind in order to be able to address exactly both the diagnostic and therapeutical procedures. A new conservatively managed case is thereby described. A review of the literature with particular attention drawn to the diagnosis and the different therapeutical possibilities is also elaborated.
