Clinical and Radiologic Characteristics, Surgical Outcomes, and Its Possible Origins of Chondroma of the Dural Convexity

Figure 1

Radiographic images and hematoxylin-eosin staining of Case 1. (a–d) Pre- and (e–g) postoperative radiographic images indicated a mass located in the right parietal area with no cystic degeneration. (a) Coronal T1-weighted images (after gadolinium enhancement) demonstrate mild multiple dot and linear enhancement. (b) Sagittal T1-weighted images demonstrate a slightly hypointense signal. (c) Axial T2 demonstrates a slightly hyperintense signal with no significant edema or mass effect in adjacent structures. (d) CT scan shows that the lesion was hyperdense with calcification. (e–g) Postoperative images show that the tumor was completely removed. (h) Hematoxylin-eosin staining of Case 1.
