Intramuscular myxomas are benign soft-tissue tumors, characterized by bland spindle-shaped cells and fibroblasts within an abundant mucoid matrix on histologic examination. Classically, these are slowly enlarging masses which may occasionally cause pain, paresthesia, and muscle weakness secondary to mass effect. We present an interesting phenomenon of two histologically confirmed cases of intramuscular myxomas that exhibited size and enhancement changes on follow-up imaging after image-guided biopsy. To our knowledge, this is the first report to describe size and enhancement changes of intramuscular myxomas after biopsy.
肌内黏液瘤是一种良性软组织肿瘤，组织学检查显示其特征为在丰富的黏液样基质内有温和的梭形细胞和成纤维细胞。典型情况下，这些是缓慢增大的肿块，偶尔可能因肿块效应导致疼痛、感觉异常和肌肉无力。我们报告了两例经组织学证实的肌内黏液瘤的有趣现象，在图像引导活检后的随访成像中，它们显示出大小和强化的变化。据我们所知，这是第一份描述活检后肌内黏液瘤大小和强化变化的报告。
