Schwannomas of the intercostal nerve, typically, are solitary and rarely originate from the mediastinum. Here, we describe two cases of multiple schwannomas occurring within a single costal interval. Both patients were misdiagnosed prior to surgery, and the correct diagnosis was made by pathological examination following surgery. Upon retrospective review of the preoperative radiographic examination, we found that such misdiagnoses may be avoided by performing 3-dimensional reconstruction.
