Spontaneous pneumocephalus and subdural hemorrhage after sneezing

Abstract

Spontaneous pneumocephalus is defined as the presence of air in the absence of intracranial factors. The management of spontaneous pneumocephalus can be conservative or surgical, and surgical intervention could be urgently required if clinical deterioration is rapid. Here, we report a case of pneumocephalus and subdural hemorrhage after sneezing. A 24-year-old male reported to our emergency department with a chief complaint of headache and dizziness. The patient gave a history of onset of headache and dizziness after 2 episodes of heavy sneezing. There was neither a history of recent traumatic episode or previous surgery, nor any signs and symptoms of recent fever or upper respiratory tract infections. Physical examination showed no specific findings. Computed tomography was performed, which showed subdural hemorrhage and PNC in the left occipital lobe, left hemomastoid, and maxillary hemosinus. A neurosurgeon was consulted, who suggested admission in the intensive care unit. An otolaryngologist was then consulted for the left ear otorrhea and hearing impairment. Otoscopic examination showed hemotympanum of the left ear, for which pain control and conservative treatment was suggested. The patient was transferred to general ward 4 days later, since the following brain computed tomography showed resolution of the hemorrhage, and discharged 6 days later because of the improved signs and symptoms. Pneumocephalus and intracranial hemorrhage can occur without a history of trauma or surgery. Special attention is required if headache, dizziness, or other neurologic signs and symptoms occur immediately after sneezing. Intracranial hemorrhage and penumocephalus should be considered in the differential diagnosis.
