Summary

A thrombosed varix, a rare deep orofacial condition, can mimic tumors. Characteristic CT and MRI findings, including high signal intensity and concentric distribution, aid in diagnosis.

Area of Science:

  • Oral pathology
  • Vascular malformations
  • Diagnostic imaging

Background:

  • Thrombosed varix typically presents as a pigmented oral mucosal mass, often mistaken for hemangioma.
  • Occurrence in deeper orofacial regions, such as the submandibular space, is infrequent.
  • This case highlights a thrombosed varix presenting with tumor-like symptoms.

Observation:

  • Clinical presentation was non-specific, lacking characteristic signs of a thrombosed varix.
  • Imaging studies, including computed tomography (CT) and magnetic resonance imaging (MRI), were crucial for evaluation.
  • The lesion exhibited high signal intensity on CT (80 HU) and a distinct concentric signal distribution on both CT and MRI.

Findings:

  • The observed imaging characteristics suggest a thrombosed varix in the submandibular space.

  • Differential diagnosis included various soft tissue tumors and vascular lesions.
  • Correlation of clinical and imaging findings was essential for accurate diagnosis.

    • Implications:

    • Recognizing these imaging patterns can improve the diagnosis of deep orofacial thrombosed varices.
    • This case expands the understanding of the clinical and radiological presentation of thrombosed varix.
    • Accurate diagnosis prevents unnecessary surgical interventions for benign vascular lesions.
