Atraumatic Subdural Hematoma in a Third-Trimester Gravid Patient.

Acute atraumatic subdural hematoma is a rare occurrence and there exist few case studies which describe suspected cases and causes for this condition. We present a case of a 36-year-old female at 32-week gestation who initially presented to the emergency department for evaluation of lower extremity cellulitis but had acute neurologic change while being in the ED. Computed tomography revealed a right subdural hematoma with midline shift and mass effect. The primary cause for the patient's subdural hematoma is unknown; however, this patient had several risk factors for developing an atraumatic subdural hematoma.
