Intramuscular hemangioma presenting with multiple phleboliths: a case report.

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.

Multiple pulp stones: a case report.

Pulp stones are usually found in the pulp chamber. Radiographically, they appear as radiopaque structures in the pulp chambers or root canals of individual teeth. Generalized pulp stones throughout the dentition are usually associated with systemic or genetic disorders of the dentine. This report presents an unusual case of a 13-year-old girl with generalized pulp stones with clinically normal crowns. The patient's main complaint was a crossbite affecting all permanent canines. Radiographic examination revealed multiple pulp stones and several teeth with atypically shaped roots. Orthodontic treatment, gingivoplasty, and esthetic restorations were performed, thus using a multidisciplinary approach to establish functionally and esthetically sound dentition.

Double dens invaginatus: report of three cases.

Dens invaginatus results from an infolding of the outer surface of a tooth. The clinical importance of dens invaginatus results from the risk of pulpal disease. So, all clinicians should be aware of this anomaly. The presence of double dens invaginatus is extremely rare. This article presents three cases of double dens invaginatus in permanent maxillary lateral incisors, one with preventive restoration on its palatal surface. They were classified as double dens invaginatus because of two enamel lined invaginations presented in the crowns of these teeth.

Extrafollicular adenomatoid odontogenic tumor of the mandible: report of a case.

The purpose of this study was to report an extrafollicular adenomatoid odontogenic tumor in the mandibular anterior region in a patient. A 15 year-old female with a painless swelling in the mandibular anterior region was referred to our clinic. Fine needle aspiration yielded no fluid. Periapical, panoramic and computer tomography scans showed circumscribed radiolucent area with fine calcifications. The lesion was totally enucleated and the teeth 31, 32 were removed. The rarity of adenomatoid odontogenic tumor may be associated with its slowly growing pattern and symptomless behavior. Therefore, it should be distinguished from more common lesions of odontogenic origin in routine dental examinations.

Impacted primary tooth and tooth agenesis: a case report of monozygotic twins.

In the present report, a case of 19 year-old monozygotic twin brothers with similar tooth agenesis and impacted primary teeth is presented. Both twins (HDH, DHH) had agenesis of ten and eleven teeth (respectively), third molars excluded, consistent with oligodontia and both had four impacted primary teeth and the permanent successors of all these primary teeth were congenitally missing. The occurrence of similarly located tooth agenesis and primary impacted teeth in monozygotic twins may suggest the influence of genetic factors in their etiology. In addition, primary tooth impaction may be related to congenitally missing tooth.
