Cervical hyperostosis can cause dysphagia. High vitamin A levels in patients without supplementation suggest a metabolic abnormality contributing to this condition.
Area of Science:
- Endocrinology
- Gastroenterology
- Orthopedics
Background:
- Vertebral hyperostosis commonly affects the thoracic spine with minimal symptoms.
- Cervical spine involvement can lead to dysphagia due to esophageal compression.
Observation:
- Three male patients (54-73 years) presented with moderate to severe dysphagia.
- Clinical findings included neck stiffness and mild pain; family history was positive in one case.
- Radiographs revealed significant anterior cervical hyperostosis, with some patients also showing thoracic and pelvic hyperostosis.
Findings:
- Standard blood tests and HLA-B27 were normal.
- Elevated serum vitamin A levels (894-1123 microg/L) were observed in all patients.
- No history of retinoid use or unusual dietary habits was reported.
Implications:
- Anterior cervical hyperostosis is a potential cause of dysphagia.
- The findings suggest a possible link between hypervitaminosis A and hyperostosis development.
- An underlying abnormality in vitamin A metabolism may be responsible for hyperostosis in these patients.
