MORENO CANTERO, F.; SUAREZ MIER, MP.    ABAD ORTIZ, L.. Traumatic rupture of arachnoid cyst resulting in acute subdural haematoma: Case report and literature review. []. , 39, pp.11-22. ISSN 1988-611X.

The presence of a subdural hematoma (SDH) in aging people is not uncommon, although it can be the cause of complex medicolegal deliberations when death occurs after a recent head trauma. We present the case of an old woman (87 years old) who is attended in a hospital emergency service after suffering a fall with closed head injury, because of progressive stupor and anisocoria several hours later. A chronic SDH with new hemorrhage was diagnosed in a cranial computerized tomography (CT) without contrast. The neuropathological examination showed an acute SDH, arachnoid cyst elements, raised intracraneal pressure lesions with Duret hemorrhage and hemorrhages characteristic of grade III diffuse axonal injury.
