“…Our results are in agreement with other authors 2, 15–19. In particular, Okayama et al16 described a case of recurrent PTMO, with an echogenic area, representing a soft tissue mass around a central area of decreased echogenicity and no evidence of calcification.…”

Purpose.The aim of this paper is to describe the sonographic (US) features of post traumatic myositis ossificans (PTMO).Methods.Fifteen patients with histopathological diagnosis of PTMO were included. The following US parameters were evaluated: presence of a mass, calcifications, power Doppler signals, and relationship with adjacent structures.Results.Five patients (33.3%) were diagnosed as early PTMO and 10 (66.6%) as mature PTMO. In both early and mature PTMO, US showed an oval hypoechoic mass, without infiltrative borders, located in a muscular belly. In the early phase, a center of less echogenicity was observed, associated with an outer sheet‐like hyperechoic peripheral rim, while, in the mature phase, peripheral calcification created more reflections and distal acoustic shadowing was observed.Conclusions.US is highly sensitive in the detection of PTMO, helps differentiate between PTMO and malignant soft tissue tumors, and can be used for follow‐up of the lesions. © 2011 Wiley Periodicals, Inc.

“…Typically, calcifications in MOC appear 2–3 weeks after the trauma and a well-developed MOC with a characteristic zonal calcification pattern becomes evident only after 4 to 6 weeks [1, 4, 21]. Hence, a three-phase bone scan or ultrasonography is necessary to detect MOC at the earliest stages of formation [22, 23]. …”

Myositis ossificans is a self-limiting ossifying process that most often develops following mechanical trauma to skeletal musculature. It chiefly affects the skeletal muscles of extremities of young athletically active adult males. Myositis ossificans is rare in children except for children affected by heritable disorder known as progressive myositis ossificans (fibrodysplasia ossificans progressiva). Children with this disorder develop ossification of muscles and associated soft tissue in early childhood without prior history of trauma. Traumatic form of myositis ossificans also known as myositis ossificans circumscripta (MOC) is rarely encountered in the head and neck musculature. We report a case of MOC within the buccinator which developed as a postoperative complication of mandibular third molar surgery. During extraction of a left mandibular third molar in a 16-year old male, a tooth fragment was accidently displaced into the adjacent soft tissue. Retrieval of this tooth fragment caused significant soft tissue trauma. Eighteen months after his third molar surgery, the patient continued to have pain and tenderness anterior to the left mandibular ramus. Radiographic imaging revealed a well-defined ovoid radiopaque mass within the left buccinator muscle. The lesion was surgically removed and the post-surgical course of the patient was uneventful. Histological findings of the mass were characteristic for myositis ossificans.

“…7 Computerized tomography scan demonstrates fascial edema and swelling in the earliest stage before ossification, 14 while magnetic resonance imaging reveals variable heterogeneously enhanced mass in the muscles depending on the age of the lesion. 15 Early stages of the lesion are usually misdiagnosed as osteosarcoma necessitating unwarranted radical surgery.…”

Myositis ossificans circumscripta is a pathological condition characterized by formation of bony tissue within the skeletal muscles following repeated trauma. A case of myositis ossificans circumscripta of the supra-orbital region in a 25-year-old man is presented and the pertinent literature is reviewed. To the best our knowledge this benign lesion has not been reported previously in the orbital region the world literature. Clinically the patient presented with a swelling and proptosis of the right eye. Radiologically there was a rounded opacity with well defined margin. Lesion was initially misdiagnosed as a fibroosseous lesion; however microscopic examination indicated matured myositis ossificans. Lesion was excised via a bicoronal flap. Careful clinical, radiological and pathologic evaluation is required to make this uncommon diagnosis in an unusual location such as the supra-orbital region to avoid unnecessary surgical mutilation of the patient. Key words: Myositis ossificans, supraorbital RésuméLa Myosite circumscripta ossificane est un état pathologique caractérisé par la formation de tissu osseux dans le muscle squelettique à la suite des traumatismes répétés. Un cas de la myosite circumscripta ossificane de la région supra orbitale chez un homme âgé de 25 ans est ici présenté et aussi la pertinence de la littérature est révisée. A notre connaissance, cette lésion bénigne n'a pas été signalée précédemment dans la région orbitale de la littérature du monde. Cliniquement le patient s'est présenté atteint du gonflement et du propose de l'oeil droit. Radiologiquement, il y avait une opacité arrondie avec des marges bien définies. Lésion a été au départ mal diagnostiqué comme une fibro-lésion osseuse ; toutefois, l'examen microscopique avait indiqué la myosite ossification mûre. Lésion a été excisée par l'intermédiaire d'un bicoronal flap. Prise en charge clinique, radiologique et évaluation pathologique est nécessaire pour faire ce diagnostique rare dans une situation inhabituelle telle que la région supra orbitale afin d'éviter les mutilations chirurgicales évitable chez le patient Mots clés Myosite ossificane, supra orbitale
