Lenz-Majewski syndrome can cause craniovertebral junction stenosis, leading to severe complications like hydrocephalus and myelopathy. Early monitoring is crucial for affected children to prevent fatal outcomes.
Area of Science:
- Pediatric Neurology
- Medical Genetics
- Neurosurgery
Background:
- Lenz-Majewski syndrome is a rare genetic disorder characterized by distinctive facial features, skeletal abnormalities, and developmental delays.
- Craniovertebral junction (CVJ) stenosis is a narrowing of the bony canal at the base of the skull where it meets the spine.
- Communicating hydrocephalus is the buildup of cerebrospinal fluid in the brain, while cervical myelopathy involves spinal cord compression in the neck.
Observation:
- This report details a case of a young girl diagnosed with Lenz-Majewski syndrome.
- The patient presented with significant craniovertebral junction stenosis, progressing rapidly in early childhood.
- This stenosis led to the development of communicating hydrocephalus and cervical myelopathy.
Findings:
- Progressive craniovertebral hyperostosis was identified as the life-threatening complication.
- Surgical intervention at 2 years of age provided initial success but was ultimately insufficient.
- The child experienced apneic spells and died suddenly at age 5 years.
Implications:
- This case highlights the critical need for vigilant monitoring of craniovertebral junction stenosis in children with Lenz-Majewski syndrome.
- Early detection and management of CVJ stenosis may reduce the significant morbidity and mortality associated with this condition.
- Further research into the specific mechanisms of craniovertebral hyperostosis in Lenz-Majewski syndrome is warranted.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
