The H- or butterfly-pattern of uptake in the sacrum on Tc-99m-methylene diphosphonate bone scintigraphy is typical of fractures of the body of the sacrum that involve the sacral alae. This report describes four patients with a focal linear or curvilinear pattern of uptake in sacral fractures without alae involvement. This pattern differs from that associated with metastases in the sacrum, which typically has a random pattern. Recognition of this scintigraphic linear dot pattern of uptake in horizontal fractures in the inferior body of the sacrum is useful for detecting fractures without alae involvement that are not readily apparent on radiographs.
在锝-99m-亚甲基二膦酸盐骨闪烁显像中，骶骨摄取呈H形或蝶形是累及骶骨翼的骶骨体骨折的典型表现。本报告描述了4例骶骨骨折患者，其摄取呈局灶性线性或曲线形，不累及骶骨翼。这种表现不同于骶骨转移瘤，后者通常呈随机分布。认识到骶骨下部水平骨折的这种闪烁显像线性点状摄取表现，有助于检测出X线片上不易发现的不累及骶骨翼的骨折。
