Summary
Multiple spinal extradural meningeal cysts (SEMCs) are rare. Surgical packing of dural defects and tenting sutures effectively treated a large infant case, relieving spinal cord compression and improving hydronephrosis.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Spinal Surgery
Background:
- Spinal extradural meningeal cysts (SEMCs) are uncommon lesions.
- These cysts communicate with the subarachnoid space via dural defects.
- Progressive spinal cord compression can occur due to SEMC expansion.
Observation:
- A 5-month-old infant presented with nine large SEMCs from T1-L5 levels, causing hydronephrosis.
- Surgical intervention involved laminoplastic laminotomy to access eight communicating SEMCs.
- Transdural communications were addressed using autologous muscle packing and fibrin glue.
Findings:
- Dural tenting sutures were employed to minimize extradural dead space.
- Postoperative relief of cord compression was achieved.
- Improvement in the infant's hydronephrosis was observed.
Implications:
- A single-stage surgical approach combining dural defect packing and tenting sutures is effective.
- This technique is beneficial for managing extensive and multiple SEMCs in infants.
- Successful surgical management can lead to significant clinical improvement in affected children.

4.0K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:30Socioemotional Development during Infancy
487
Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

4.0K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

1.9K
The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

01:25Multiple Voltage Sources
1.8K
Generally, a single battery is not enough to power some devices. In such cases, batteries can be combined in two ways: in series or in parallel.
In series, the positive terminal of one battery is connected to the negative terminal of another battery. Hence, the voltage of each battery is added to give the net voltage, which is increased because each battery boosts the electrons that enter it. The same current flows through each battery because they are connected in series.
