Abstract

We report a case involving the development of a delayed acute subdural hematoma (ASDH) after trauma, with the absence of any abnormal radiological and clinical findings at initial examination. A 54-year-old male visited the emergency department after a minor trauma. The patient only complained of mild headache after head injury. He presented no abnormal findings on neurological examination, and brain computed tomography (CT) did not show any intracranial lesion or skull fractures. However, he developed seizure with disorientation eight hours after trauma, and ASDH with midline shift was found during a follow-up CT. He recovered without neurological deficits after immediate primary care and admission to the neurosurgery department. On serial follow-up CT images, a gradually increasing mass effect of hematoma was detected, and removed by craniotomy. The patient recovered without neurologic deficits.

Figure

  • FIGURE 1 (A) Initial computed tomography (CT) shows no abnormalities. (B) Follow-up CT shows acute subdural hematoma on left cerebral convexity on 8 hours after trauma.

  • FIGURE 2 (A) Computed tomography scan disclose increasing mass effect of hematoma and midline shift of approximately 10 mm. (B) Diffusion weighted magnetic resonance image shows mixed density of delayed acute subdural hematoma.

  • FIGURE 3 (A) Postoperative computed tomography (CT) after hematoma evacuation shows the recovered midline. (B) CT reveals recurrent acute subdural hematoma on 3rd postoperative day (C) CT scan shows no additional hematoma or other abnormal findings at discharge.
