Summary
A dermal-sinus-like stalk mimics spinal congenital dermal sinus (DS) but lacks DS complications. Surgical intervention is recommended for diagnosis due to subtle differences.
Area of Science:
- Neurology
- Developmental Biology
- Surgical Pathology
Background:
- Spinal congenital dermal sinus (DS) is a common birth defect.
- Dermal-sinus-like stalk is a rare anomaly that mimics DS.
- Distinguishing between these conditions is crucial for appropriate management.
Observation:
- Three cases of suspected spinal DS were analyzed.
- A unique anatomical configuration, the dermal-sinus-like stalk, was identified.
- Cases presented with a skin dimple and a solid tract extending into the spinal canal.
Findings:
- Dermal-sinus-like stalk is distinct from true DS and lacks associated complications.
- Clinical, radiological, and surgical findings highlight differences, though differentiation can be challenging.
- No infections or dermoid/epidermoid tumors were observed in these cases.
Implications:
- Early surgical intervention is recommended for suspected cases.
- Accurate diagnosis is essential to prevent potential complications associated with true DS.
- Understanding this malformation aids in surgical planning and patient outcomes.

01:54The Spinal Cord
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
01:15Spinal Cord: Gross Anatomy
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
01:23Spinal Nerves: Anatomy
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

01:26Spinal Cord
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.
01:16Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:10Spinal Cord: Information Processing
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...
