Summary
Hajdu-Cheney syndrome, a rare congenital disorder, causes bone deformities and skull abnormalities. This case highlights specific MRI findings including brainstem shift due to basilar invagination.
Area of Science:
- Genetics and Rare Diseases
- Skeletal Dysplasias
- Neuroimaging
Background:
- Hajdu-Cheney syndrome is a rare genetic disorder characterized by distinctive skeletal abnormalities.
- Key features include acro-osteolysis, osteoporotic changes, and basilar invagination with skull deformities.
Observation:
- A 32-year-old male patient presented with symptoms consistent with Hajdu-Cheney syndrome.
- Magnetic resonance imaging (MRI) revealed a significantly deformed skull with an almost horizontal basal angle.
- The MRI also showed an elongated and upwardly shifted brain stem due to odontoid process invagination.
Findings:
- The invagination of the skull base by the odontoid process of the second cervical vertebra was a prominent finding.
- Associated neuroimaging findings included an atrophic pituitary gland and a widely open sella turcica.
- Symmetrical fluid collections along the optic nerve sheath were also observed.
Implications:
- This case underscores the complex craniofacial and neurological manifestations of Hajdu-Cheney syndrome.
- Detailed MRI analysis is crucial for diagnosing and understanding the anatomical challenges in affected individuals.
- Understanding these findings aids in managing potential complications related to brainstem compression and pituitary dysfunction.
