Acute Onset Lateral Foot Pain • Xray of the Week63 y.o. male presented with 1 hour of aching pain on the lateral aspect of the right midfoot after he felt a pop while climbing stairs. He had no loss of sensation, stiffness, or swelling, but pain limited his range of motion. Initial x-rays of the right foot and ankle were taken with a follow up right foot MRI. What is the diagnosis? Figure 1. Prior oblique (A), current oblique (B) and current frontal (C) radiographs of the right foot. Figure
Introduction Mazabraud's syndrome is a rare but well-described disorder characterized by fibrous dysplasia in single or multiple bones associated with one or more soft-tissue myxomas. In this report, we describe what is, to the best of our knowledge, the first case involving an intra-osseous myxoma. This finding supports, and could provide new insight into, the pathological association between fibrous dysplasia and myxomas. Case presentation In this report, we describe the case of a 49-year-old Caucasian woman known for years to have fibrous dysplasia in the left femur and tibia who presented with progressive pain in her left leg and soft swelling in the left quadriceps region. After surgical intervention with excision of the soft-tissue mass, the diagnosis of Mazabraud's syndrome was confirmed. During follow-up, our patient presented with a painless mass located on the lateral side of the left knee, next to a second, intra-osseous lesion with the same characteristics in the left lateral tibial plateau. The histopathological examination was consistent with a soft-tissue intra-osseous myxoma. Conclusion In the international literature, 67 cases of Mazabraud's syndrome have been described so far. To our knowledge, the present case report is the first to describe the combination of polyostotic fibrous dysplasia and intra-muscular as well as intra-osseous myxoma.
