Computerized transverse axial tomography (CTAT) in the diagnosis of epilepsy. 1977

G Scollo-Lavizzari, and K Eichhorn, and R Wüthrich

99 patients with late epilepsy were investigated in our EEG laboratory. In intervals of maximal 100 days (averaged 23 days) a waking EEG recording and a CTAT were carried out. The average age was 43. 62.5% of the pathological CTATs were found in partial seizures with elementary symptomatology. In patients with generalized seizures the diagnosis of symptomatic epilepsy could be made in 20 cases (34%) with the help of computerized tomography. Generalized seizures were related to tumors only in 8.5% in our case material. In 20 of 99 EEGs in our patients there was a continuous delta wave focus, 12 of these with epileptogenic activity. Of these 20 patients, 18 showed a pathological result in computerized tomography. Eight tumors or metastases, 8 cases of atrophy (7 local and 1 diffuse) as well as 1 case of encephalitis could be diagnosed. 12 EEGs showed continuous or intermittent theta wave foci. Computerized tomography never gave a pathological finding in these patients. If one compares the results of CTAT and EEG in cases of tumor, the agreement between positive tomography and the pathological EEG is very high (97%): 33 positive CTATs comapred with 31 positive EEGs. Our investigations with computerized tomography show organic findings in 34 of 99 epilepsies, that is about 34%.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009362	Neoplasm Metastasis	The transfer of a neoplasm from one organ or part of the body to another remote from the primary site.	Metastase,Metastasis,Metastases, Neoplasm,Metastasis, Neoplasm,Neoplasm Metastases,Metastases
D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D001932	Brain Neoplasms	Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.

D004569	Electroencephalography	Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.	EEG,Electroencephalogram,Electroencephalograms
D004827	Epilepsy	A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).

D004832	Epilepsy, Absence	A seizure disorder usually occurring in childhood characterized by rhythmic electrical brain discharges of generalized onset. Clinical features include a sudden cessation of ongoing activity usually without loss of postural tone. Rhythmic blinking of the eyelids or lip smacking frequently accompanies the SEIZURES. The usual duration is 5-10 seconds, and multiple episodes may occur daily. Juvenile absence epilepsy is characterized by the juvenile onset of absence seizures and an increased incidence of myoclonus and tonic-clonic seizures.
