Introducción: El condrosarcoma es un tumor maligno poco común; la localización craneal es rara. En ocasiones, su resección total no es posible debido a la proximidad de la masa a estructuras vasculares y neurales importantes. Caso Clínico: Mujer de 56 años que presentó cefalea en el lado derecho, parestesia en el lado derecho del labio superior, pérdida de la memoria a corto plazo y ageusia. La RM mostró una masa extraaxial realzada. La paciente tuvo una resección quirúrgica completa. Los resultados anatomopatológicos mostraron un condrosarcoma bien diferenciado de la base del cráneo. Conclusión: El condrosarcoma es un tumor maligno con diferenciación pura del cartílago hialino, representa el 0.15 % de todos los tumores intracraneales, siendo este el segundo caso de localización de la base del cráneo reportado en el Perú. Las características histológicas más los mar...

Introduction:Chondrosarcoma is an unusual malignant neoplasm; cranial location is rare. Sometimes its complete resection is not possible because of vicinity of the mass to important vascular and neural structures. Clinical case: This is a 56-year old female subject who developed headache in the right side, paresthesia in the right side of her upper lip, short term memory loss, and ageusia. A magnetic resonance imaging study showed an enhanced extra-axial mass. This patient underwent complete surgical resection. The anatomopathological study showed a well differentiated chondrosarcoma of the cranial base. Conclusion: Chondrosarcoma is a malignancy with pure differentiation of the hyaline cartilage. It represents 0.15% of all intracranial tumors, and this is the second case with a cranial base location reported in Peru. Both histological characteristics and immunohistochemistry markers rev...
