IMAGING FEATURE OF ECCHORDOSIS PHYSALIPHORA: A REPORT OF 2 RARE CASES
Main Article Content
Abstract
Ecchordosis physaliphora is a rare, benign lesion originating from the notochord. The lesion typically demonstrates benign imaging characteristics on MRI, showing no evidence of bone invasion or involvement of adjacent structures. It is usually located in the midline, anterior to the pons, and posterior to the clivus. Because it shares a notochordal origin with chordoma, histopathological differentiation between the two entities can be challenging. Therefore, imaging plays a crucial role in diagnosis. We report two cases illustrating the typical radiologic spectrum of this rare lesion.
