Background:
Acute subdural hematomas are frequently seen in brain trauma-injured patients. However, spontaneous subdural hematomas are uncommon, especially those localized in the posterior fossa, where fewer than 10 case reports have been described in the medical literature.
Case Description:
We describe a patient who suddenly had a headache and progressed rapidly to coma and signs of brainstem compression. She was diagnosed with posterior fossa subdural hematoma after image examinations that were endorsed by surgical findings. A posterior fossa craniectomy was performed and was associated with blood drainage.
Conclusions:
The patient had a great outcome, with no neurologic deficits at hospital discharge and the 1-year follow-up.

Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
