Hydranencephaly synonyms

Hydranencephaly is a rare neurological condition characterized by the absence or severe underdevelopment of the cerebral hemispheres, which are the two large parts of the brain responsible for higher cognitive functions. This condition is typically present at birth and is caused by a disruption in the normal brain development during pregnancy.

Although the exact cause of hydranencephaly is not fully understood, it is believed to be a result of vascular insults or infections that occur during early pregnancy. The condition is often associated with a poor prognosis, as the absence of functional brain tissue can lead to severe developmental delays and neurological impairments.

There are several synonyms used to describe hydranencephaly, including:

• Hydranencephalia: This term is derived from the Greek words "hydra" meaning water and "encephalos" meaning brain. It reflects the characteristic feature of the condition, which is the presence of fluid-filled sacs in place of the missing brain tissue.


• Hydrocephalus internus: This term refers to the internal accumulation of cerebrospinal fluid within the brain. It is often used interchangeably with hydranencephaly due to the presence of fluid-filled spaces in the brain.


• Encephaloclastic porencephaly: This term describes the presence of cystic cavities or gaps within the brain tissue. It is often used to describe severe cases of hydranencephaly where there is complete absence of brain tissue.

It is important to note that while these terms are used synonymously, they may have slightly different connotations and implications in the medical literature.

Overall, hydranencephaly is a rare and devastating condition that significantly impacts the affected individuals and their families. Early diagnosis and appropriate management are crucial in providing supportive care and optimizing the quality of life for individuals with this condition.
