Calvarial lesions: a radiological approach to diagnosis.
Calvarial lesions are frequently identified in radiological studies. A wide variety of neoplasms and non-neoplastic lesions can involve the calvarium, and their imaging appearances vary according to their pathologic features. These lesions are usually asymptomatic but may manifest as a lump with or without associated pain. Clinical information, including the age of patient, is an important factor in the diagnostic process. In this paper, we illustrate the value of cross-sectional imaging techniques by computed tomography (CT) and magnetic resonance imaging (MRI) in evaluating these lesions. We also review the literature and discuss the specific imaging characteristics of the most common calvarial lesions in order to provide information that can guide radiological diagnosis or limit differential diagnosis.
