Reveal Findings

Prenatal MR – Mixed signal lesion at the caudothalamic groove protruding into the lateral ventricle.

Reveal Discussion

Hemorrhage usually appears as a hypointense area on T2-weighted images. Intraventricular hemorrhage can appear as debris layering in the dependent portion of the ventricle or as a focal hematoma. The detection of small subependymal hemorrhages is more difficult, partly because the normal germinal matrix has similar signal intensity to blood (hypointense on T2-weighted images and hyperintense on T1-weighted images) because of its high cellularity. Gradient-echo sequences may be useful to help to confirm the presence of blood, because the hemorrhage appears more hypointense than the germinal matrix. Differential diagnosis of signal disturbance at the caudothalamic groove includes infection and tuberous sclerosis.
