摘要：
骨骨瘤骨膜型（POS）是一种分化良好的低级别恶性肉瘤，位置位于骨骼表面。颞骨POS极其罕见，在现代文献中仅有少数几例。在这里，我们报道了一例偶然发现的颞骨POS，其临床表现不典型。我们还回顾了该实体的独特影像学和组织病理学特征，并讨论了为什么在这种疾病中发展广泛的鉴别诊断和进行早期干预被认为是必要的。© 2023 The Authors. Published by Elsevier Inc. on behalf of University of Washington.
Parosteal osteosarcomas (POS) are well-differentiated low-grade malignant sarcomas that are located on the surface of the bone. POS of the temporal bone is exceptionally rare, with less than a hand full of cases present in modern literature. Here, we report a POS of the temporal bone found incidentally and with an uncharacteristic presentation. We also review the unique imaging and histopathological findings of this entity and discuss why developing a broad differential diagnosis and proceeding with early intervention are considered imperative in this disease.© 2023 The Authors.
