Cranial X-ray is of limited value in the evaluation of epilepsy and should be performed only when CT is not available and there is a suspicion of a calcified lesion associated with the seizures, such as in areas endemic for cysticercosis. Additionally, other conditions can be associated with intracranial calcifications, including Sturge-Weber disease, tuberous sclerosis, and celiac disease. Although diagnosis of these conditions is usually apparent from general examination, when there is doubt, X-ray can show typical patterns of calcified lesions that render these diagnoses more likely. Finally, the detection of skull fractures following epileptic drop attacks is another potential indication for cranial X-ray.
