Summary
This case highlights how acute lymphoblastic leukaemia (ALL) can present with skeletal lytic lesions, mimicking Langerhans cell histiocytosis on imaging. Early diagnosis is crucial to differentiate these conditions and ensure appropriate treatment.
Area of Science:
- Oncology
- Radiology
- Hematology
Background:
- Acute lymphoblastic leukaemia (ALL) is a common childhood cancer.
- Skeletal involvement in ALL can manifest as lytic lesions.
- Radiological differentiation between ALL and other conditions like Langerhans cell histiocytosis is critical.
Observation:
- A 14-year-old female with diagnosed ALL presented for pre-bone marrow transplant oral screening.
- Maxillofacial radiographs revealed multiple, well-defined, non-corticated radiolucent lesions in the skull and mandible.
- These lesions were widespread throughout the skeletal frame, causing pain.
Findings:
- The observed radiological features mimicked Langerhans cell histiocytosis.
- However, a prior bone marrow biopsy confirmed ALL.
- This case underscores the potential for ALL to present with significant skeletal lytic lesions.
Implications:
- Radiologists and clinicians should consider ALL in the differential diagnosis of widespread skeletal lytic lesions, especially in pediatric patients.
- Accurate differentiation is vital to avoid misdiagnosis and ensure timely, appropriate treatment for ALL.
- Reporting such presentations aids in understanding the diverse manifestations of leukemia.
