Hydrocephalus (term delivery)
Findings
- Large, heterogeneous mass centered in the quadrigeminal plate region measuring 6 x 2.8 x 6 cm
- Extensive corresponding mass effect on the midbrain with effacement of the cerebral aqueduct and associated severe obstructive hydrocephalus with cerebral parenchymal thinning
- Small volume hemorrhage layering in both lateral ventricles and fourth ventricle with rounded clot in the third ventricle
- Small volume scattered subarachnoid hemorrhage
- Additional noncontiguous masses in the left cerebellopontine angle cistern and along the ependymal margin of the frontal horn of the left lateral ventricle at the caudothalamic groove
- The above described masses demonstrate areas of restricted diffusion (particularly the two smaller lesions) but no discrete enhancement
Diagnosis
