Many disorders produce similar or overlapping patterns of bone marrow edema in the ankle. Bone marrow edema may present in a few hindfoot bones simultaneously or in a single bone. The purpose of this pictorial essay is to provide guidelines based on clinical history and specific MRI patterns and locations to accurately identify the cause of ankle bone marrow edema. We will first focus on bone marrow edema in general disease categories involving multiple bones, such as reactive processes, trauma, neuroarthropathy, and arthritides. A discussion of bone marrow edema in individual bones of the ankle and hindfoot including the tibia, fibula, talus, and calcaneus will follow. Helpful hints for arriving at the correct diagnosis will be provided in each section.
After review of this article, radiologists should be able to use their knowledge of clinical history and specific MRI patterns and locations to accurately distinguish between the various causes of bone marrow edema in the ankle and hindfoot.
许多疾病都会导致踝关节骨髓水肿出现相似或重叠的模式。骨髓水肿可能同时出现在几个后足骨中，也可能出现在单个骨中。本影像学专题文章旨在根据临床病史和特定的 MRI 模式和位置提供指导，以准确确定踝关节骨髓水肿的原因。我们将首先关注涉及多个骨骼的一般疾病类别的骨髓水肿，如反应性过程、创伤、神经关节病和关节炎。接下来将讨论踝关节和后足的个别骨骼（包括胫骨、腓骨、距骨和跟骨）的骨髓水肿。在每个部分中，我们将提供有助于得出正确诊断的提示。
阅读本文后，放射科医生应该能够运用其对临床病史和特定 MRI 模式及位置的了解，准确区分踝关节和后足骨髓水肿的各种原因。
