Intraventricular hemorrhage (IVH) occurs only in the lateral ventricles, and hydrocephalus develops. Which area is likely blocked?
Answer:
Foramen of Monro.
Explanation:
Lateral ventricles > 3rd ventricle via right and left interventricular foramina of Monro.
3rd ventricle > 4th ventricle via cerebral aqueduct of Sylvius.
4th ventricle > subarachnoid space via:
Foramina of Luschka = Lateral.
Foramen of Magendie = Medial.
CSF made by choroid plexuses located in the lateral and fourth ventricles. Travels to subarachnoid space via foramina of Luschka and Magendie, is reabsorbed by arachnoid granulations, and then drains into dural venous sinuses.
