Lumbar Vertebral Fracture Through a Pre-Existing Schmorl's Node Mimicking Histopathologically a Low-Grade...

Area of Science:

• Orthopedic Surgery
• Pathology
• Radiology

Background:

• Schmorl's nodes (SN) are common benign vertebral inclusions.
• Fractures through SNs are rare and can present diagnostic challenges.

Observation:

• A patient with a first lumbar vertebra (L1) fracture through a pre-existing SN initially received a false diagnosis of low-grade chondrosarcoma.
• Histopathological findings mimicked malignancy, leading to oncological staging and further investigation.

Findings:

• Despite initial pathology reports, subsequent imaging and clinical recovery suggested a benign process.
• Multidisciplinary tumor board re-evaluation attributed the findings to the fracture through the SN, not a true neoplasm.

Implications:

• This case underscores the critical role of multidisciplinary tumor boards in resolving diagnostic discrepancies.
• Increased awareness is needed for rare presentations where histopathology may misleadingly suggest malignancy.
