Intensity Modulated Radiotherapy [IMRT] in a Rare Case of Infratemporal Chondrosarcoma with Intracranial Extension in a Young Adolescent Patient

Abstract

Mesenchymal chondrosarcoma is a malignant neoplasm of cartilaginous origin. It is an uncommon subtype of chondrosarcoma which is described in the young adolescent population. We present a rare case of chondrosarcoma in a teenage group-a 16yr old pediatric patient. This 16 year old patient came to us with progressive, painless, right facial asymmetry of 3 months duration .MRI scan showed a large lobulated enhancing lesion in right infratemporal fossa and masticator space with destruction of right mandibular bone with intracranial extension. She underwent subtotal excision [R2 resection] followed with adjuvant radiotherapy by Intensity modulated radiotherapy technique (IMRT) and remains disease free for 1.5 years on follow up. Role of chemotherapy is not defined. Combined modality approach including surgery and radiotherapy maximizes the chances of cure despite the aggressive biology of mesenchymal chondrosarcomas.
