title: Fibroid in the buttock: an unexpected diagnosis.
abstract: Uterine leiomyomas (fibroids) are very common lesions with well-described imaging features. We present an unusual case of a fibroid which presented in the buttock with atypical clinical and imaging features in a woman who had had a previous hysterectomy. Despite extensive imaging and biopsies, the diagnosis was not suspected until pathological evaluation of the resected mass. The differential diagnosis for such a lesion, and the imaging and pathological features of fibroids, including atypical and parasitic leiomyomas, are discussed.
