   Aug 23, 2023 · Obstructive hydrocephalus develops from a block in CSF pathways. The obstruction most commonly occurs at the foramina Monro, the aqueduct of Sylvius, the fourth ventricle, and foramen magnum, but most tumors with a significant size can obstruct at any point of CSF pathways.

    MRI. This test uses radio waves and a magnetic field to produce detailed images of the brain. This test is painless, but it is noisy and requires lying still. MRI scans can show enlarged ventricles caused by excess cerebrospinal fluid. MRI also can be used to find causes of hydrocephalus or other conditions contributing to symptoms.
