Clinical question: 35- week old infant with apnea. Evaluate for intracranial abnormality. Signs and symptoms: Apnea. Unenhanced head CT:There is no evidence of intracranial hemorrhage, mass-effect, midline shift or hydrocephalus. Although there is no suggestion of any edematous changes of brain parenchymal immature brain parenchymal can obscure subtle edema brain parenchyma. If clinical concern for ischemic change is high recommend an MRI examination. The cortical sulci, ventricular system and CSF cisterns are unremarkable for patient's stated age. No definitive abnormality in the posterior fossa is detected. Calvarium is intact.
