Abstract

Ecchordosis Physaliphora (EP) is a benign lesion originating from the developing notochord, similar to chordoma. We report complete resection of asymptomatic, extradural EP in the sphenoid sinus using an endoscopic transsphenoidal approach and review surgical approaches to resection.

Highlights

ConclusionsEndoscopic approaches to resection allow for excellent visualization and resection of clival Ecchordosis Physaliphora (EP). Endoscopic endonasal transsphenoidal approaches are minimally invasive options for resection of EP of the anterior clivus, for lesions extending into the sphenoid sinus
Ecchordosis physaliphora (EP) and chordoma are uncommon lesions which originate from the embryonic notochord

Summary

Conclusions

Clear differentiation between EP and chordoma is often difficult. Diagnostic, and surgical features must be considered for diagnosis [6,26]. Invasive approaches to surgery may be valuable when definitive diagnosis has not yet been reached. An endoscopic endonasal transsphenoidal approach allowed for complete resection without brain retraction or dural infringement. The approach should be considered for lesions extending into the sphenoid sinus, as it provides direct access to the sinus and retroclival space
