Infantile cortical hyperostosis

Unusual findings on infantile cortical hyperostosis: A case report

BACKGROUND

Caffey's disease is a rare syndrome, usually self-limiting, affecting newborn and young infants. On radiological exams, the cortical hyperostosis is always present, associated or not to soft tissue swelling. Other radiographic presentations are described as lytic areas.

AIM

This article has the objective to relate computed tomography (CT) findings of Caffey's disease, where lytic lesion on mandibular angle was the principal radiological manifestation.

METHODS AND RESULTS

Three-dimensional reconstructions were performed to demonstrate the initial aspect and the healing process.

CONCLUSION

This report shows unusual radiological characteristics of Caffey's disease on CT and its progressive resolution.

Mandibular periostitis ossificans in immature large breed dogs: 5 cases (1999-2006)

This case series describes clinical, radiographic, and histopathological features of mandibular swellings in 5 immature, large breed dogs. The dogs originated from different regions of the United States. In each case, intraoral dental radiography of the jaw swelling revealed a two-layered (double) ventral mandibular cortex. Biopsy was performed in 4 of the 5 puppies, revealing periosteal new bone formation. Resolution of the mandibular swelling was spontaneous in the 4 dogs available for follow-up examination. The authors postulate that the clinical, radiographic, and histopathological presentation of mandibular swelling in these 5 dogs is a distinct pathological entity consistent with an inflammatory condition of the maturing human mandible known as periostitis ossificans.
