1. Understand cross sectional calvarial anatomy 2. Recognize the characteristic imaging findings of various calvarial lesions 3. Use location, key imaging features, and radiological pearls to accurately diagnose calvarial lesions

1. Review cross sectional calvarial anatomy categorized into the outer table, diploic space, and inner table 2. Case-based presentation with emphasis on the location and distinguishing imaging features of the following benign and malignant calvarial lesions:    - Outer Table        Parietal thinning        Osteoma        Emissary vein    - Diploic Space        Diploic veins        Venous lakes        Epidermoid        Dermoid        Eosinophilic granuloma        Hemangioma    - Inner Table        Arachnoid granulations        Meningioma        Hyperostosis frontalis interna    - All Tables        Parietal foramen        Leptomeningeal cyst        Cephalocele        Multiple myeloma        Metastasis        Paget’s disease        Acromegaly        Fibrous dysplasia 3. Review of some fundamental rules to keep in mind when trying to distinguish benign from malignant calvarial lesions 4. Summary table of lesions classified by location within the calvaria
