Abstract

Primary Ewing's sarcoma of the skull is a very rare entity. We report MRI findings in a case of Ewing's sarcoma of the greater wing of sphenoid in a 4-year-old patient. Magnetic resonance imaging showed markedly heterogenous signal intensity with areas of haemorrhage and necrosis. It also demonstrated the exact extent of tumour due to its multiplanar capabilities and was, therefore, helpful in planning surgery.

摘要

原发性颅骨尤文肉瘤是一种非常罕见的疾病。我们报告了一名4岁患者蝶骨大翼尤文肉瘤的MRI表现。磁共振成像显示信号强度明显不均匀，伴有出血和坏死区域。由于其多平面成像能力，它还能准确显示肿瘤范围，因此有助于手术规划。
