Abstract: Objective: Hodgkin lymphoma can be treated by radiotherapy or chemotherapy alone or combined. Meningiomas account for 1-4.2% of all primary intracranial tumors in children, and chordoid meningioma is a very rare subtype. In this study, we investigated a case of an intraparenchymal chordoid meningioma that developed during the early stage in a patient with Hodgkin lymphoma who had been treated with radiotherapy.

Case: A 10-year-old male patient was diagnosed with Hodgkin lymphoma and was treated with a combination of radiotherapy and chemotherapy. He presented at our emergency service 6 years later. He had a fever and was suffering from discomfort and insignificant left hemiparesis (4/5). Contrast-enhanced cranial magnetic resonance imaging (MRI) showed a mass in the right temporoparietal region. The intracranial lesion was surgically excised. The tumor was identified as a WHO grade 2 chordoid meningioma by the pathological examination. The Ki-67 proliferation index was found to be 20-25%.

Conclusion: Surgeons must remember that radiation-associated meningiomas may occur in the early stage of the treatment as well as in the late stage. Young patients with grade 2 chordoid meningiomas must be followed-up in case of recurrence, and tumors with high Ki-67 indexes are highly expected to relapse.
