Adenosarcoma of the uterus is a rare tumor containing benign glandular epithelial and malignant mesenchymal elements. Typical adenosarcoma is a low-grade tumor, presents as a large polypoid mass occupying the endometrial cavity, and may protrude into the vaginal cavity. The presence of small hyperintense cysts scattered within the mass on T(2)-weighted imaging, reflecting glandular epithelial components, and relatively low signal intensity on high b-value diffusion-weighted imaging, reflecting its low-grade nature, may be characteristic findings.
子宫腺肉瘤是一种罕见的肿瘤,包含良性腺上皮和恶性间叶成分。典型的腺肉瘤是一种低级别肿瘤,表现为占据子宫内膜腔的大的息肉样肿物,且可能突出至阴道腔内。在T2加权成像上肿块内散在分布的小的高信号囊肿,反映腺上皮成分,以及在高b值扩散加权成像上相对低的信号强度,反映其低级别性质,可能是其特征性表现。
