The traumatic bone cyst: a new dimension

Area of Science:

• Oral and Maxillofacial Surgery
• Skeletal Biology
• Radiology

Background:

• Traumatic bone cysts (TBCs) are benign, fluid-filled intraosseous lesions typically presenting in the mandible.
• Their etiology is often debated, with trauma frequently implicated, though not always definitively proven.
• Standard TBCs usually follow a predictable, non-aggressive clinical course.

Observation:

• This report details an exceptionally large traumatic bone cyst discovered in an unusual anatomical location.
• Radiographic evidence confirmed the cyst's presence for at least five years prior to the current presentation.
• The lesion exhibited aggressive growth characteristics, diverging from the typical TBC presentation.

Findings:

• The presented case highlights a TBC of unprecedented dimensions and location.
• The long-term radiographic history demonstrates a slow but persistent growth pattern.
• The aggressive nature of this specific TBC challenges conventional expectations for this pathology.

Implications:

• This case expands the known spectrum of traumatic bone cyst presentation and behavior.
• It underscores the importance of long-term radiographic monitoring for bone lesions.
• Further research may be warranted to understand factors contributing to TBC aggressiveness and unusual presentations.
