Symptomatic bilateral choroid plexus xanthogranuloma in a pediatric patient.

INTRODUCTION: Central nervous system xanthogranulomas are uncommon clinical entities, and symptomatic bilateral choroid plexus xanthogranulomas are rare. CASE PRESENTATION: We present the case of a 15-year-old male patient with bilateral choroid plexus xanthogranulomas with symptoms of increased intracranial pressure. Gross total resection of the tumor in the left lateral ventricle was performed. The patient improved, and asymptomatic right-sided tumor was monitored at follow-up. CONCLUSION: The main treatment objective in these tumors is gross total resection. Asymptomatic tumors can be followed without intervention. However, surgery should be performed for symptomatic tumors that cause hydrocephalus or symptoms of increased intracranial pressure.

Spine Metastasis of Thymic Carcinoma in a Pediatric Patient: A Case Report and Comprehensive Literature Review.

INTRODUCTION: Thymic carcinoma metastases of the spinal column are very rare, especially in pediatric patients. To our knowledge, this is the first such pediatric case in the literature. CASE PRESENTATION: We report the case of a 14-year-old male patient with T12 and L1 metastases of thymic carcinoma. He had history of thymectomy and intrathoracic tumor resection 7 months previously. The patient's neurological condition deteriorated; therefore, tumor resection and decompression of the spinal canal were performed. He underwent instrumentation and fusion procedures to prevent spinal instability. CONCLUSION: The main purpose of the treatment is gross total resection of the thymic carcinoma. However, adjuvant methods such as radiotherapy and chemotherapy should be added to the treatment protocol in patients who have higher stage diseases or those in whom total tumor resection cannot be achieved.
