Calcified leiomyoma of deep soft tissue in a child.

We report the case of a 7-year-old boy with a calcified leiomyoma in the right gluteal muscle. Radiography and CT showed a well-defined soft tissue mass with mulberry-like calcifications that superficially resembled chondroid matrix calcification. The mass exhibited high-signal intensity intermingled with spotty low-signal intensity on T2-weighted MRI which was attributable to extensive non-malignant degeneration of the tumour.
