Myositis ossificans mimicking sarcoma, the importance of diagnostic imaging - case report.

Luczyńska E, Kasperkiewicz H, Domalik A, Cwierz A, Bobek-Billewicz B - Pol J Radiol (2014)

Bottom Line: Myositis ossificans is localized inflammatory process affecting skeletal muscles.Very rarely it can affect one of the neck muscles and present as a neck tumor, it can be misdiagnosed as the clinical, radiological and histological examinations can mimic a sarcoma.The aim of this study was to present the differential diagnosis based on diagnostics imaging between MO and malignant tumors, such as parosteal sarcoma, synovial sarcoma and malignant fibrous histiocytoma.

ABSTRACT

Background: Myositis ossificans is localized inflammatory process affecting skeletal muscles. Very rarely it can affect one of the neck muscles and present as a neck tumor, it can be misdiagnosed as the clinical, radiological and histological examinations can mimic a sarcoma.

Case report: We report a 29 year old female patient with neck tumor suspected to be a sarcoma who underwent full diagnostics imaging and open bipsy with histopatological examination, afterwards surgical excision was performed.

Conclusions: The aim of this study was to present the differential diagnosis based on diagnostics imaging between MO and malignant tumors, such as parosteal sarcoma, synovial sarcoma and malignant fibrous histiocytoma.

f6-poljradiol-79-228: Coronal, T1-weighted image after administration of gadolinium contrast demonstrates marked enhancement within the lesion.

Mentions: Magnetic Resonance Imaging with angiography: (Figures 3–6) revealed a relatively well – defined left-sided mass measuring 28×24×26 mm in diameter. The lesion was hyperintense on T1-WI and heterogeneous, isointense to hyperintense on T2-WI. Low-SI rim was seen in all sequences. T2-WI also demonstrated high-SI perilesional edema along muscle fibers. There was diffuse enhancement of the tumor and surrounding edematous region on post-contrast T1-WI.
