  • Title: Intramuscular hemangioma presenting with multiple phleboliths: a case report.
    Author: Zengin AZ, Celenk P, Sumer AP.
    Journal: Oral Surg Oral Med Oral Pathol Oral Radiol; 2013 Jan; 115(1):e32-6. PubMed ID: 23217548.
    Abstract:
    A rare case of intramuscular hemangioma of the masseter muscle with multiple phleboliths is described, highlighting features evident in plain radiography, ultrasound, and magnetic resonance imaging (MRI). A 21-year-old woman presented with a complaint of swelling of the right masseter muscle. A plain radiograph from the soft tissue of the right cheek showed a large number of round, target-like radiopacities that varied in size. Ultrasound revealed a lobulated cystic lesion in the right masseter muscle with increased echogenicity. MRI showed a space-occupying lesion in the right masseter muscle, which was isointense on T1-weighted image close to the muscle tissue and hyperintense on T2-weighted image, containing fields with no signal septations. A plain soft tissue radiograph can demonstrate phleboliths and aid in the diagnosis of an intramuscular hemangioma. In addition, nonionized techniques such as ultrasound and MRI can provide useful information to clinicians regarding the location of calcifications and the structure of masses.
