CEREBRAL angiography provides the most accurate means for study of the intracranial status after severe closed-head trauma. Surgical intervention is clearly indicated if well defined intra- or extra-axial masses are demonstrated. If balancing, bilateral, intra-axial masses are not appreciated, however, patients may be denied proper surgical treatment. Diffuse, bilateral brain injury resulting in contusion or “pulping” of two or more of the anterior poles of the brain is such a condition. “Pulping” is defined as hemorrhage, edema, and necrosis of brain tissue (1, 3). The symmetry of mass effect may minimize any midline vessel shift, so that the severity and volume of tissue injury may be grossly underestimated. Prompt removal of hematoma and contused brain in this situation may be life-saving or improve the chances for more normal recovery of brain function. Three representative cases of bilateral anterior brain injury follow. Case Reports CASE 1. A. II., a 5l-year-cld man with a history of previous myocardial infarction, was admitted about four hours after a 15-foot fall down a chute containing waste glass. He was unconscious at first but slowly improved to a restless, irrational, partially cooperative state. Radiographs showed a left occipital linear fracture, clouding of the sphenoid sinus, and compression of L1 vertebra. While his multiple lacerations were being repaired, the patient was noted to move his legs less well than before. Laminectomy was considered but deferred because of the head injury. Lumbar puncture showed an opening pressure of 600 mm of cerebrospinal fluid and bloody spinal fluid. The echoencephalogram disclosed a normal midline position. For twenty-four hours the patient improved slightly, then became more obtunded, prompting right brachial angiography. This showed bilateral frontal lobe swelling (Fig. 1). The same day he underwent bifrontal craniotomy for removal of intracerebral dot and contused, necrotic brain from both frontal lobes. Postoperatively the patient improved greatly, was alert, talking, recognized members of his family, but at times was mildly disoriented. However, on the eighth postoperative day he died suddenly, following another myocardial infarction. CASE II: R. W., a 19-year-old boy, was comatose and immobile for forty-five minutes after an auto accident, then became increasingly restless and combative by the time of admission six hours later. He was completely disoriented, without lateralizing findings, and had normal pupillary responses. Bilateral carotid arteriograms showed evidence of bifrontal and bitemporal intra-axial masses (Fig. 2). During the following day his condition fluctuated, showing occasional pupillary inequality, bradycardia, and slight right hemiparesis. He improved with intravenous 20 per cent Mannitol until the next day when he became decerebrate, with dilated and fixed pupils.
