FIG 4. Huge subdural hematoma (after a fall down stairs a week earlier) in a fetus of 34 weeks’ gestation. US showed the bilateral hematoma with a fluid-fluid level, an enlarged right choroid plexus, and a hyperechogenicity in the posterior part of the right hemisphere.
A and B, Axial T1-weighted (A) and T2-weighted (B) sections at the level of the lateral ventricles. The hematoma is hyperintense in A and has intermediate signal intensity in B. Right hemisphere and frontal part of the left hemisphere are hypointense in A and hyperintense in B in relation to gliosis. Cortical hyperintensity in the right hemisphere (arrows) and posterior part of the left hemisphere corresponded to laminar necrosis during NFP study (not shown).
C, T2*-weighted coronal section shows marked hypointensity of the right choroid plexus (arrow) in relation to hemorrhage.
