Case report on the spontaneous resolution of a traumatic intracranial acute subdural haematoma: evaluation of the guidelines

Rapid spontaneous resolution of traumatic acute subdural haematomas (ASDH) can occur but is rare. We present an 88-year-old female who presents with a large left acute subdural haematoma (ASDH) measuring 18 mm in thickness with midline shift of 10.7 mm. We managed her conservatively based upon good consciousness level and absent neurological deficits. Repeat computed tomography (CT) the following day demonstrated near complete resolution of the ASDH and midline shift regression; a further CT confirmed resolution. Most patients with large ASDH require surgical evacuation; however, in rare cases, they can resolve spontaneously with extreme rapidity. Conservative management can be a valid option in carefully selected cases
