[Juvenile osteopetrosis: a case report]

Area of Science:

• Pediatric Hematology
• Skeletal Dysplasias
• Medical Genetics

Background:

• Juvenile osteopetrosis is a rare, inherited disorder characterized by impaired osteoclast function, leading to defective bone resorption.
• This condition results in abnormally dense and brittle bones, increasing the risk of fractures and other complications.
• Early diagnosis and intervention are crucial due to the potentially lethal nature of severe infantile osteopetrosis.

Observation:

• A 3 1/2-month-old female infant presented with failure to thrive, nasal obstruction, anemia, and hepatosplenomegaly.
• Radiographic examination revealed characteristic dense, sclerotic bones, consistent with osteopetrosis.
• The clinical presentation highlighted the systemic impact of the disease beyond skeletal abnormalities.

Findings:

• The case illustrates the typical clinical and radiographic features of infantile-onset juvenile osteopetrosis.
• The described symptoms underscore the severity and multi-system involvement of the disease in affected infants.
• Dense sclerotic bones on radiography are a hallmark diagnostic finding.

Implications:

• Bone marrow transplantation (BMT) is a potentially curative treatment for juvenile osteopetrosis, particularly in severe cases.
• Successful BMT can restore normal bone remodeling and resolve systemic complications associated with the disease.
• This case emphasizes the importance of considering BMT for infants diagnosed with juvenile osteopetrosis to improve outcomes.
