Soft-tissue hemangiomas have been described in MR imaging, but a histopathologic correlation to better understand the MR appearance has not been reported. Five patients with intramuscular soft-tissue hemangiomas were imaged in orthogonal planes on a 1.5-T system with spin-echo (SE) short-TR/TE sequences (600/20) and long-TR/TE sequences (2500/20-80). Complete intact surgical specimens were obtained, and gross and histopathologic findings were compared with MR findings. A striated-septated configuration with a high signal intensity on long-SE sequences (TE greater than 75 msec) correlated with endothelial-lined vascular channels separated by fibrous and/or fatty linear strands. An awareness of the morphologic MR pattern of soft-tissue hemangiomas may aid in recognition of these lesions.
软组织血管瘤已在磁共振成像中有所描述，但尚未有关于通过组织病理学关联以更好理解磁共振表现的报道。5例肌肉内软组织血管瘤患者在1.5-T系统上采用自旋回波（SE）短TR/TE序列（600/20）和长TR/TE序列（2500/20 - 80）进行正交平面成像。获取完整的手术标本，并将大体和组织病理学发现与磁共振成像结果进行比较。在长SE序列（TE大于75毫秒）上具有高信号强度的条纹状分隔结构与由纤维和/或脂肪线性条索分隔的内皮衬里血管通道相关。了解软组织血管瘤的形态学磁共振模式可能有助于识别这些病变。
