Summary

This study reports four cases of hemophilic pseudotumors, which are rare bone lesions caused by bleeding in patients with hemophilia. These pseudotumors occurred in unusual locations, including the skull and long bones, presenting unique diagnostic challenges.

Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Hematology

Background:

  • Hemophilic pseudotumors are rare, destructive bone lesions resulting from recurrent intraosseous bleeding in patients with hemophilia.
  • While commonly affecting long bones, they can occur in unusual locations, posing diagnostic challenges.

Observation:

  • This report details four cases of proved hemophilic pseudotumors.
  • Five lesions were identified in uncommon sites: cranial vault, mandible, phalanx, distal femur, and distal tibia.

Findings:

  • Conventional radiography and computed tomography revealed expansile osteolytic destruction, cortical thinning, and pathological fractures.
  • Ultrasonography demonstrated cortical expansion with internal echogenicity and soft tissue extension.
  • Technetium-99m DTPA scans indicated increased vascular flow and uptake in affected bones.

Implications:

  • These findings highlight the diverse radiographic presentations of hemophilic pseudotumors in unusual locations.
  • Accurate diagnosis requires a combination of imaging modalities and awareness of these rare manifestations.
  • Understanding these presentations is crucial for effective management and surgical planning in hemophilia patients.
