Bauer","Chun-Chieh Lin","Geoff Appelboom","George Zanazzi"],"abstract":"Background: Composite hemangioendothelioma (CHE) is a rare, locally aggressive neoplasm of intermediate malignant potential. It is composed of a mixture of vascular tumors with a predilection for the dermis and subcutis of the extremities. Case Description: In this report, we describe a 41-year-old man who presented with a 2-month history of headache, dizziness, and intermittent seizures. Magnetic resonance imaging showed a hemorrhagic, multilobulated, and dural-based mass with extension into the calvarium. The mass measured 10.3 × 4.8 × 4 cm along the interhemispheric fissure and encased the superior sagittal sinus. Excision was performed, and histopathologic examination revealed a heterogeneous mixture of vascular components consisting of epithelioid hemangioendothelioma, retiform hemangioendothelioma, and hemangioma. This is the first report of a primary intracranial CHE. Conclusion: The spectrum of mesenchymal neoplasms within the cranium expands to encompass CHE.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/29c25400-e847-477e-9ae1-cc16ec44524f/featured/hero-1781559725984.png","publishDate":"2024-02-23T00:00:00.000Z","doi":"10.25259/SNI_3_2024","categories":["Neuropathology","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2024/02/12765/SNI-15-55.pdf"}
