Nonmeningothelial Dural-Based Lesions: A Histopathological Analysis

Abstract: Introduction We report 30 cases of nonmeningothelial dural-based lesions encountered during a 3-year study period. Materials and Methods We retrospectively reviewed pathology records of patients operated for extra-axial, dural-based lesions during the years 2016 to 2018 and included nonmeningothelial lesions as a part of this study. Results Among the 3,243 neurosurgical specimens for histopathologic examination, only 30 (0.93%) were “nonmeningothelial dural-based lesions.” Six (20%) patients were in the pediatric age group. Pathologic assessment identified 13 cases of solitary fibrous tumor/hemangiopericytoma (43.3%) and 7 cases of Ewing's sarcoma/primitive neuroectodermal tumor (23.3%). Two cases (6.7%) were of metastasis. Other lesions included a single case each of non-Hodgkin's lymphoma, undifferentiated sarcoma, solitary plasmacytoma, and granulocytic sarcoma. Nonneoplastic lesions included two cases each of Rosai–Dorfman disease and nonspecific inflammatory lesions. Conclusion Nonmeningothelial dural-based lesions being rare, thorough examination of morphological features is a must by the pathologist, to arrive at the accurate diagnosis. Ancillary tests, if required, should be employed in the context of the morphologic picture.
