Radiographic features of Ollier's disease - two case reports.

Area of Science:

• Orthopedics
• Radiology
• Pediatric Endocrinology

Background:

• Ollier's disease is a rare, non-hereditary skeletal disorder characterized by multiple enchondromas.
• It typically affects the metaphysis of long bones, often with unilateral predominance, and occurs in early childhood.
• Clinical presentation includes hard swellings, deformities, leg discrepancies, and pathological fractures.

Observation:

• Two pediatric cases of Ollier's disease are presented, a 13-year-old female and an 8-year-old boy.
• Radiographs revealed multiple expansile enchondromas in various bones, including phalanges, long bones, iliac bones, and ribs.
• The patients exhibited deformities and leg discrepancies, with one case presenting without specific initial symptoms.

Findings:

• Conventional radiography is the primary diagnostic tool for Ollier's disease, identifying characteristic enchondromas.
• The disease typically does not require specific treatment.
• Understanding clinical and radiographic features aids in avoiding unnecessary advanced imaging.

Implications:

• Accurate diagnosis based on clinical and radiographic findings is crucial for appropriate patient management.
• Knowledge of typical presentations can prevent the overuse of advanced imaging modalities like MRI or ultrasound.
• Further imaging may be reserved for complex or painful presentations of Ollier's disease.
