Absence of septum pellucidum

What causes absence of the septum pellucidum?

Absence of the septum pellucidum can be caused by multiple factors depending on the underlying condition. Some people are born with or develop hydrocephalus, or a fluid buildup in the brain. If this condition goes untreated, the excess fluid can disintegrate the septum pellucidum. Absence of the septum pellucidum can also be the result of a genetic condition that is present in a baby at birth. Additionally, the septum pellucidum is connected to another brain structure called the corpus callosum, which is responsible for sending information between the two halves of the brain. Some people are born with a missing corpus callosum. People with a missing corpus callosum will also have a missing septum pellucidum.
