The clinical and computed tomographic (CT) features of three consecutive cases of temporal lobe contusion emphasize the presentation and frequent subsequent progressive neurological deterioration. The initial presentation was one of lethargy and combativeness with little or no focal neurological deficits. Thereafter all patients developed progressive neurological deterioration with decreasing levels of consciousness and lateralizing signs. Computed tomography (CT) which aided in making the initial diagnosis was repeated following clinical deterioration. Worsening in the patient's clinical condition correlated positively with changes within the contusion as visualized by CT.
