Computed tomography (CT) of the head [Figure 1] demonstrated subcutaneous hematomas along the bilateral scalp without evidence of underlying fracture or intracranial pathology.
(a) Axial T2 MRI brain demonstrating bilateral subgaleal fluid collections, enlarged compared to noncontrast CT had a week prior, (b) sagittal T1 flair brain demonstrating collections along the frontal and parietal aspects of the calvarium, and (c) coronal noncontrast T1 MRI of the brain demonstrating bilateral subgaleal hematoma formation.

Magnetic resonance imaging (MRI) of the brain with and without intravenous gadolinium was performed, demonstrating an interval increase in bilateral frontal and parietal scalp hematoma to 2.3 cm, compared to prior noncontrast CT of the head [Figure 2].
Approximately 300 mL of dark, motor oil-like fluid was aspirated under sterile technique, with a reduction in mass and bogginess of the forehead.
