LEPTOMENINGEAL CYSTS Meaning and
Definition
-
Leptomeningeal cysts, also known as arachnoid cysts, are fluid-filled sacs that form within the arachnoid membrane, one of the three layers that cover the brain and spinal cord. These cysts typically develop during fetal development or early childhood and are considered congenital in nature. They are composed of cerebrospinal fluid (CSF) and are often located in the subarachnoid space, which is the area between the arachnoid and pia mater layers.
Leptomeningeal cysts are often asymptomatic and may be discovered incidentally during imaging tests performed for unrelated reasons. However, when symptoms do occur, they can vary depending on the location, size, and pressure exerted by the cyst on surrounding structures. Common symptoms may include headaches, seizures, developmental delay, behavioral changes, visual disturbances, and focal neurological deficits.
Diagnosis of leptomeningeal cysts usually involves medical history evaluation, physical examination, and imaging studies such as CT scans or MRI scans. Treatment options may depend on the severity of symptoms and can range from conservative management with regular monitoring to surgical interventions aimed at draining or removing the cyst. In some cases, the cysts may not require treatment if they are small and asymptomatic.
It is important to note that leptomeningeal cysts are different from other types of cysts that can occur within the brain or spinal cord, such as epidermoid cysts or dermoid cysts. These other cysts contain different types of tissue and may have different clinical presentations and treatment approaches.

Etymology of LEPTOMENINGEAL CYSTS
The word "leptomeningeal" is derived from two Greek terms: "lepto", meaning "thin" or "slender", and "meninx", meaning "membrane". In medical terminology, "leptomeningeal" refers to the pia and arachnoid membranes, which are the two innermost layers surrounding the brain and spinal cord.
The term "cyst" comes from the Greek word "kustis", meaning "bladder" or "pouch". In medicine, a cyst refers to a sac or closed cavity in the body that contains fluid, air, or other substances.
Therefore, "leptomeningeal cysts" describe fluid-filled sacs or pouches located within or near the thin membranes (leptomeninges) that cover the brain and spinal cord.
