MRI of focal fibrocartilaginous dysplasia

Area of Science:

• Pediatric Orthopedics
• Medical Imaging
• Pathology

Background:

• Focal fibrocartilaginous dysplasia (FFCD) is an uncommon, benign condition.
• It is frequently associated with unilateral tibia vara in pediatric patients.
• Understanding its imaging characteristics is crucial for accurate diagnosis.

Observation:

• This study reviewed clinical, pathological, plain film, and MRI findings in two children with FFCD.
• MRI revealed virtually identical findings in both patients.
• These imaging findings correlated well with pathological results.

Findings:

• Focal fibrocartilaginous dysplasia demonstrates a typical appearance on magnetic resonance imaging (MRI).
• Characteristic plain film findings are also indicative of FFCD.
• MRI is generally not required when plain film findings are typical.

Implications:

• Accurate diagnosis of FFCD can be achieved through characteristic plain film findings.
• MRI may be reserved for cases with atypical clinical presentations or ambiguous plain film results.
• This understanding aids in appropriate utilization of diagnostic imaging in pediatric tibia vara.
