Introduction: Skull vault lesions are often asymptomatic and are usually discovered incidentally during computed tomography or magnetic resonance imaging of the brain. Calvarial lesions can be benign or malignant. Calvarial lesions may arise from skull bones or can be secondary to invasion of skull vault from brain or scalp based lesions. Objectives: The aim of this study is to study the role of CT and MRI in evaluating skull vault lesions. Material and methods: 50 patients with skull vault lesions were considered in our study.The patients underwent CT and MRI scans of head. Results: Among 50 patients, most common skull vault lesions were Skull metastases, osteoma and epidermoid cyst. Chordoma, osseous hemangioma and intraosseous meningioma were the least encountered lesions. Conclusion: This article has demonstrated that CT and MRI have complementary roles in determining the nature of skull lesions. CT is the most accurate method for evaluating bone destruction of the inner and outer tables while MRI is best to assess marrow involvement, soft tissue component and invasion of adjacent tissues.
