Newborn who experienced prolonged labor

CT of caput succedaneum
Axial (above), coronal (below left) and sagittal (below right) CT without contrast of the brain show a large low density fluid collection in the subcutaneous tissues of the scalp that crosses sutures and is seen to surround the skull on the coronal view. Intracranially, there is diffuse loss of gray matter-white matter differentiation secondary to diffuse cerebral edema.

The diagnosis was caput succedaneum in a patient with hypoxic ischemic encephalopathy.
