Anencephaly: Lateral View of Fetal Developmental Abnormality in Neural Tube Defects
The image depicts a lateral (side) view of an anencephalic fetus, revealing the characteristic absence of the cranial vault and cerebral hemispheres. Anencephaly represents one of the most severe forms of neural tube defects, occurring when the rostral (head) end of the neural tube fails to close during early embryonic development. This devastating congenital malformation is incompatible with prolonged survival, with most affected newborns surviving only hours to days after birth. The lateral perspective provides medical professionals with important diagnostic visualization of the craniofacial profile typical in anencephaly, showing the absent cranial vault, exposed rudimentary brain tissue, and distinctive facial features that result from this profound developmental failure.

Anencephaly in Newborns
Anencephaly is one of the most severe neural tube defects compatible with life until birth, characterized by the absence of a major portion of the brain, skull, and scalp. The image depicts an anencephalic newborn in profile view, illustrating the distinctive craniofacial features associated with this condition. Anencephaly results from failure of the rostral (head) end of the neural tube to close during embryonic development, typically between the 23rd and 26th day of gestation. This devastating congenital anomaly is universally fatal, with most affected newborns surviving only hours to days after birth. Understanding the characteristic physical manifestations, underlying pathophysiology, and available management options is essential for healthcare professionals involved in perinatal and neonatal care.
Neuropathology
The anterosuperior view of the head of an anencephalic fetus
Anencephaly is a severe congenital birth defect characterized by the absence of major portions of the brain, skull, and scalp. The image shows an anterosuperior view of an anencephalic fetus, demonstrating the distinctive facial features and cranial abnormalities that define this condition. This devastating neural tube defect occurs during early embryonic development when the neural tube fails to close properly at the cranial end, resulting in the absence of significant portions of the brain, particularly the cerebrum and cerebellum. Despite these profound structural abnormalities, the brainstem and spinal cord often remain intact, allowing for basic physiological functions in affected fetuses.

Occipital Encephalocele in Neonates
The image depicts a neonate with a significant occipital encephalocele, visible as a large sac-like protrusion from the back of the infant's head. Encephalocele is a severe congenital neural tube defect characterized by herniation of brain tissue and meninges through a defect in the skull. This particular case shows a substantial occipital encephalocele with intact skin coverage and visible vascularity. The condition requires prompt multidisciplinary evaluation and neurosurgical intervention to minimize complications and optimize developmental outcomes. Early diagnosis, careful surgical planning, and comprehensive follow-up care are essential components in the management of this challenging congenital anomaly.

Parietal Encephalocele in a Two-Year-Old Child
The image depicts a two-year-old child with a parietal encephalocele, visible as a prominent protrusion from the superior aspect of the skull. Encephalocele is a rare congenital neural tube defect characterized by the herniation of brain tissue and meninges through a defect in the cranium. This case is notable as most encephaloceles are surgically addressed in early infancy, but this child appears to have reached two years of age with the condition still present. The sac appears well-vascularized with a reddish, taut appearance, suggesting active blood supply to the herniated tissues. This condition requires comprehensive neurosurgical evaluation and intervention to prevent further complications and optimize developmental outcomes.

Encephalocele is a severe congenital neural tube defect characterized by the herniation of brain tissue, meninges, and cerebrospinal fluid through a defect in the cranium. This particular case demonstrates an extremely large occipital encephalocele, which presents significant challenges for surgical management and has important implications for neurological outcomes. The condition requires immediate attention from a multidisciplinary team including neurosurgeons, neonatologists, and plastic surgeons to optimize outcomes and minimize complications associated with this rare but serious congenital anomaly.
Neuropathology
Encephalocele in Neonates
Encephalocele is a rare congenital neural tube defect characterized by the protrusion of brain tissue and meninges through a defect in the skull. The image depicts an infant with an occipital encephalocele, the most common form of this condition in Western countries, appearing as a sac-like protrusion from the back of the head. This serious birth defect occurs during early embryonic development when the neural tube fails to close properly, resulting in an opening in the skull through which brain tissue and cerebrospinal fluid can herniate. Early diagnosis, comprehensive evaluation, and timely surgical intervention are crucial for optimizing developmental outcomes in affected infants.
Musculoskeletal Pathology
Lumbar Myelomeningocele
A lumbar myelomeningocele is the most severe form of spina bifida, characterized by the protrusion of spinal cord tissue and meninges through a defect in the vertebral column. The image shows two perspectives of a lumbar myelomeningocele in a newborn, displaying the characteristic red, sac-like structure containing neural elements protruding from the lower back. This congenital defect requires prompt surgical intervention to prevent infection, preserve neurological function, and improve long-term outcomes.
