22 day old female ex-24 week premature with abnormal head ultrasound. No acute intracranial hemorrhage.Again seen is a low attenuation it least partially extra-axial fluid collection overlying the superior right frontal lobe as was seen on multiple previous sonogram examinations. Additionally there appears to be a low density component within the parenchyma of the right frontal lobe which may reflect a parenchymal component. This collection is causing a mass effect with a left of midline shift of approximately 3 mm. Given the limitations of brain CT in newborns further characterization is limited. MRI could be obtained for further characterization of this abnormality.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1. Right frontal extra-axial and intraparenchymal collection causing left of midline shift as detailed above. Given the limitations of brain CT newborns, further characterization could be obtained with MRI.
