[Two cases of infantile cortical hyperostosis (monostotic form) (author's transl)]
Insights
Infantile cortical hyperostosis, a bone disorder, presented in two infants with clavicle involvement. Both monostotic cases showed significant regression within six months, highlighting the condition's self-limiting nature.
Area of Science:
- Pediatrics
- Orthopedics
- Medical Case Reports
Background:
- Infantile cortical hyperostosis (ICH) is a rare bone disorder affecting infants.
- The monostotic form involves a single bone, often the long bones or clavicle.
- Etiology and pathogenesis of ICH remain largely unknown.
Observation:
- Two cases of monostotic infantile cortical hyperostosis are presented.
- Case 1: Right clavicle involvement, presenting at six weeks of age, possibly congenital.
- Case 2: Left clavicle involvement in a 7-month-old infant, following an upper respiratory infection.
Findings:
- Both infants presented with clavicle hyperostosis.
- Both cases demonstrated significant clinical and radiographic regression within six months.
- The condition appears to be self-limiting in these monostotic presentations.
Implications:
- These cases contribute to understanding the clinical spectrum of infantile cortical hyperostosis.
- The rapid regression suggests a favorable prognosis for monostotic ICH.
- Further research is needed to elucidate the underlying causes and mechanisms of ICH.
Abstract:
Two cases of infantile cortical hyperostosis, both of the monostotic form, are described. In the first patient the right clavicle was involved; the disease may have been present from birth, but resulted in the infant's admission at the age of six weeks. The second patient was a 7-month old infant who developed the disease after an upper respiratory tract infection. There were only minor changes in the left clavicle. Both cases regressed almost completely within six months. The discussion deals with the largely unsolved problems concerning infantile cortical hyperostosis.
