Simple bone cyst: possible misdiagnosis in periapical pathology

Area of Science:

• Dentistry
• Oral Pathology
• Radiology

Background:

• Simple bone cysts are benign, non-neoplastic intraosseous lesions.
• They can present with varied clinical and radiographic features, sometimes mimicking other pathologies.
• Distinguishing simple bone cysts from odontogenic lesions is crucial for appropriate treatment.

Observation:

• An 18-year-old male presented with pain and significant bony radiolucency in the mandibular right second molar region.
• Initial clinical and radiographic examinations suggested chronic apical periodontitis.
• Surgical exploration revealed an empty bone cavity, inconsistent with a periapical lesion.

Findings:

• The lesion was diagnosed as a simple bone cyst based on surgical observation.
• The cyst was treated by surgical exploration and curettage.
• Post-operative follow-up at one year showed complete radiographic and clinical healing.

Implications:

• Simple bone cysts can present atypically, challenging differential diagnosis in endodontics.
• Thorough clinical and radiographic assessment is vital to exclude other pathologies.
• Surgical management, including curettage, can be effective for simple bone cysts in the jaw.
