Myositis Ossificans: A Case Report of Multiple Recurrences Following Third Molar Extractions and Review of the Literature

Precervical myositis ossificans in an infant secondary to child abuse

“…Myositis ossificans is a benign entity exemplified by ossification within soft tissue or muscle, typically secondary to trauma [1,2]. MO manifests in a highly specific chronological pattern of clinical and radiological findings that is advantageous in diagnosis [1,2,4,5].…”

“…MO manifests in a highly specific chronological pattern of clinical and radiological findings that is advantageous in diagnosis [1,2,4,5]. The initial or developmental stage involves rapid growth of a soft tissue mass that is firm and tender upon palpation.…”

“…Three to five weeks after the mass first appears, ossification begins peripherally and progresses centrally. Imaging thereafter exhibits a distinctive zoning pattern [1,2,4,5]. As the lesion matures, the peripheral calcification becomes more rim-like and there is a central lucency.…”

“…This entity is typically acquired and self-localized, with approximately 75% of cases caused by trauma [1,2]. Etiologies include blunt or penetrating trauma, fracture, surgical incision and cutaneous burns.…”

“…Etiologies include blunt or penetrating trauma, fracture, surgical incision and cutaneous burns. MO is typically seen in men ages 20 to 40 years, with the average age being 26 years [1,2]. Eighty percent of cases develop in the large muscles of the extremities; lesions rarely occur in the head and neck region.…”
