A 59-year-old woman diagnosed with a Grade I chondrosarcoma in T7 underwent total vertebrectomy. Analysis of the surgical piece established diagnosis of a Grade 1 chondrosarcoma confined to T7. Surprisingly, an infiltration with diffuse large B-cell lymphoma was found. Systemic disease was ruled out and diagnosis was established as intracompartmental Grade 1 chondrosarcoma colliding with intraosseous extranodal diffuse large B-cell lymphoma. Resection of chondrosarcoma was considered complete and treatment with four cycles of RCHOP was indicated. Two years after surgery, the patient remains at complete metabolic response. To date, this is the first reported case of chondrosarcoma colliding with lymphoma. Although Grade 1 chondrosarcoma is typically managed with local control through complete surgical resection, the mentioned finding of the lymphoma indicated the need for systemic treatment with immunochemotherapy.

Petroclival approaches remain challenging given abundant cranial nerves and vessels. Common trajectories include transsphenoidal, transoral, middle fossa-extradural, and posterior through the cerebellar peduncle. We report a unique intra-axial, intradural approach to the petroclival and cavernous sinus.

Magnetic resonance imaging (MRI) is key in evaluating central cartilage tumors. The BACTIP (Birmingham Atypical Cartilaginous Tumour Imaging Protocol) protocol assesses central cartilage tumor risk based on the tumor size and degree of endosteal scalloping on MRI. It provides a management protocol for assessment, follow-up, or referral of central cartilage tumors.

Chondrosarcomas (CHS) constitute approximately 20% of all primary malignant bone tumors, characterized by a slow growth rate with initial manifestation of few signs and symptoms. These malignant cartilaginous neoplasms, particularly those with dedifferentiated histological subtypes, pose significant therapeutic challenges, as they exhibit high resistance to both radiation and chemotherapy. Ranging from relatively benign, low-grade tumors (grade I) to aggressive high-grade tumors with the potential for lung metastases and a grim prognosis, there is a critical need for innovative diagnostic and therapeutic approaches, particularly for patients with more aggressive forms.
