Non Traumatic Myositis Ossificans Mimicking a Malignant Neoplasm: A Case Report
ABSTRACT
Myositis ossificans is a benign self limiting condition that usually related to trauma. Despite a clinically and histologically distinct entity, myositis ossificans still causes considerable difficulties in diagnosis. A 33-year-old Moroccan woman presented with a 2-month history of left inguinal inflammatory pain with limping gait, MRI examination suggested a malignant neoplasm such as soft tissue osteosarcoma. A diagnosis of myositis ossificans was made by incisional biopsy. Conservative management with clinical and radiological follow up of 19 months confirm the diagnosis. The symptoms resolved within seven months. Myositis ossificans should be considered by clinicians as a possible diagnosis for a soft tissue lesion.
