Abstract:
Focal myositis is a commonly referenced, infrequently reported and poorly documented benign inflammatory pseudotumor which may be misdiagnosed clinically as a malignant tumor. We report the clinicopathologic features and magnetic resonance imaging findings in a case of focal myositis in the thigh of a 55-year-old woman. A different radiologic presentation of this disorder is described. The gross appearance of the lesion, previously undescribed, appears to be rather specific for such a pseudoneoplastic disorder, and correlates very well with the magnetic resonance imaging features.
