This report details a rare "solid" variant of aneurysmal bone cyst in a 12-year-old girl. The study discusses its unique clinico-pathological features and diagnostic challenges.

Area of Science:

  • Orthopedics
  • Pathology
  • Radiology

Background:

  • Aneurysmal bone cysts (ABCs) are benign, expansile bone lesions typically filled with blood-filled spaces.
  • The "solid" variant of ABC is uncommon and presents distinct morphological characteristics.
  • Understanding these variants is crucial for accurate diagnosis and treatment planning.

Observation:

  • A 12-year-old female presented with backache and a palpable thoraco-spinal mass at Th 3.
  • Radiological imaging suggested a conventional aneurysmal bone cyst.
  • The resected lesion exhibited a complex morphology with fibroblastic, fibrohistiocytic, fibromyxoid, osteoclastic, and osteoblastic components, alongside small aneurysmal sinusoids.

Findings:

  • The case represents a "solid" variant of aneurysmal bone cyst, deviating from the typical cystic structure.

Related Experiment Videos

  • Histopathological examination revealed a mixed cellular composition, including reactive bone formation.
  • Differential diagnosis was considered against other bone tumors and lesions with similar imaging features.

    • Implications:

    • This case highlights the importance of considering rare variants in the differential diagnosis of bone lesions.
    • Accurate clinico-pathological correlation is essential for managing aneurysmal bone cysts.
    • Further research into the pathogenesis and behavior of solid ABC variants may improve patient outcomes.
