Imaging the patient with epilepsy
(2016) p.117-134- Abstract
Approximately 4 % of the general population will experience a seizure during their lifetime. Imaging in these "first-ever" seizure patients is in most cases normal, and abnormalities are only present in approximately 15 % of patients as seizures can be provoked by fever, sleep deprivation, stroboscopic lights, or drugs. However, an underlying lesion will lower the seizure threshold and thus make a patient more susceptible to experience a seizure. As "first-ever seizures" are a medical emergency, the treatment modality of choice in these cases is an unenhanced CT to exclude acute medical emergencies that may go along with seizures prior to a more extensive workup depending on clinical history and presentation. Imaging abnormalities... (More)
Approximately 4 % of the general population will experience a seizure during their lifetime. Imaging in these "first-ever" seizure patients is in most cases normal, and abnormalities are only present in approximately 15 % of patients as seizures can be provoked by fever, sleep deprivation, stroboscopic lights, or drugs. However, an underlying lesion will lower the seizure threshold and thus make a patient more susceptible to experience a seizure. As "first-ever seizures" are a medical emergency, the treatment modality of choice in these cases is an unenhanced CT to exclude acute medical emergencies that may go along with seizures prior to a more extensive workup depending on clinical history and presentation. Imaging abnormalities encountered in patients experiencing their first-ever seizures include (but are not restricted to) virtually all diseases affecting the brain. As such you may find vascular abnormalities (such as microangiopathy, arteriovenous malformations (AVM), sinus thrombosis, hemorrhage, cavernomas, or stroke), tumors (metastases, primary tumors), infections (encephalitis, meningitis, abscess), sequelae of previous head injury, and toxic or metabolic conditions (e.g., PRES) in these patients.
