Retrocrural capillary hemangioma: a case report

An enlarged retrocrural mass was incidentally discovered in a 79-year-old male patient. Preoperative chest computed tomography and thoracolumbar junction spine magnetic resonance imaging indicated the possibility of a paraganglioma, Castleman disease, or neurogenic tumor. Due to the large size of the tumor, malignancy could not be ruled out, and we decided to perform surgery for diagnostic and therapeutic purposes. Video-assisted thoracoscopic surgery was safely performed, and histopathological examination revealed a capillary hemangioma.
