What happens if the foramen of Monro is obstructed?

What happens if the foramen of Monro is obstructed?

The foramen of Monro is a short conduit between the paired lateral ventricles and the third ventricle of the brain. This deep structure becomes clinically significant when obstructed and leads to obstructive (non-communicating) hydrocephalus.

Can hydrocephalus be unilateral?

Unilateral hydrocephalus is a rare anomaly that can be recognized by prenatal sonography. Even though unilateral ventriculomegaly may be marked, early diagnosis and treatment may result in a favorable clinical outcome.

What does the foramen of Monro connect?

The interventricular foramen, also known as foramen of Monro, is part of the ventricular system and the connection between the third ventricle and the lateral ventricle.

What causes unilateral hydrocephalus?

The causes of unilateral hydrocephalus were agenesis or stenosis of the foramen of Monro in three cases, transient obstruction of the foramen in one fetus with an intraventricular hematoma, underlying brain dysplasia in one fetus with a variant of holoprosencephaly, and undetermined in one case.

What connects the 3rd and 4th ventricles?

The third ventricle is connected to the fourth ventricle via the cerebral aqueduct (also called the aqueduct of Sylvius).

What is unilateral mild Ventriculomegaly?

Unilateral ventriculomegaly was defined as an atrial width > 10 mm, affecting only one side of the brain, detected during the second or third trimester of pregnancy.

What is foramen of Magendie?

The foramen of Magendie (also called median aperture) is one of the foramina in the ventricular system and links the fourth ventricle and the cisterna magna. It is one of the three sites that cerebrospinal fluid (CSF) can leave the fourth ventricle and enter the subarachnoid space.

What is the function of the interventricular foramen?

opening between the lateral ventricles and the third ventricle, which allows cerebrospinal fluid to pass between them.

What is foramen of Luschka?

Background. The foramen of Luschka is a natural aperture between the fourth ventricle and the subarachnoid space at the cerebellopontine angle. Membranous closure of this foramen is referred to as primary obstruction.

What is unilateral Ventriculomegaly?

Where is tela choroidea located?

lateral ventricles
The tela choroidea lies along the choroidal fissure in the medial wall of the lateral ventricles where it is vascularized by one anterior choroidal artery (coming off of the internal carotid artery) and several choroidal branches of the posterior cerebral artery (the medial and lateral posterior choroidal arteries) 1,6 …
