Skull base chondrosarcomas (SBC) clinched the #1 position for chondroid malignancies which commonly select a synchondrosis when they rarely involve the skull base. This case illustrates the typical radiological appearances of a type of skull base tumor known as a chondrosarcoma. Both chordomas and chondrosarcomas are rare lesions and represent less than 1% of all intracranial tumors. [ 2 ] Radiosurgery following surgical decompression is currently practiced.

Chrondroid tumors are more frequently encountered than bone infarcts. Chordomas are uncommon malignant tumors of the axial skeleton that account for 1% of intracranial tumors and 4% of all primary bone tumors. Methods: The median follow-up was 36 months (range, 3-90 mo) in the chordoma cohort, and 67 months (range, 15-125) in the chondrosarcoma cohort.

This area is critically important because it supports the brain and allows all the neurovascular structures to either enter or exit the skull. Chondrosarcoma is a type of bone cancer that develops in cartilage cells. Chordomas of the skull-base are typically slow-growing, notochord-derived tumors that most commonly originate along the clivus. In addition, CT C/A/P may be indicated to evaluate for metastatic Dz, particularly for high-grade histologies. Skull base chordomas and chondrosarcomas require advanced radiosurgery or radiotherapeutical technologies capable of delivering high-dose, high-precision radiation. Both magnetic resonance imaging (MRI) and computed tomography (CT) are very sensitive to pathology of the skull base, but over the last two decades of innovation in imaging, it has become apparent that high-quality MRI is vital to both diagnosis and treatment planning in this neuroanatomic region. high supply vs cresco can i 39re apply for green card after abandonment Chondrosarcoma of skull base, Radiology point of view 1. Classic Clue: Skull-based mass exhibiting an affinity for the petro-occipital fissure sometimes showing chondroid matrix, characterized by low T1 and high T2 signal.
