Contrast-enhanced magnetic resonance imaging (CEMRI) revealed a T1 hypointense and T2 hyperintense midline lesion (4.6 cm x 2.5 cm x 5 cm), with ill-defined fat planes with bulbospongiosus muscle and progressive enhancement on dynamic contrast sequence, suggesting a suspicion of soft tissue sarcoma or hemangioma [Figure 1].

The mass was encapsulated lying deep to left bulbospongiosus muscle and was completely excised [Figure 2].
(a) Gross specimen showing well-encapsulated soft spongy mass. (b) Photomicrograph showing encapsulated tumor with spindle-shaped and stellate cells embedded in myxoid background. Tumor cells are elongated and have vesicular nuclei and moderate cytoplasm with intervening vessels consistent with angiomyxoma
